A Complete Beginner's Guide to ArcGIS Desktop (Part 3)

so i'm going to deactivate these layers and i will go back to the arc catalog and i do not have so many different types of raster data over here i just have one raster which is a dem which stands for digital elevation model so if i drag this and drop it over here you can see that in terms of the appearance it's quite different from the vector data that we are used to seeing and if i happen to zoom in like this you can see that this entire image is actually made out of different pixels i'm not sure if it's clear for you guys in this way or not but for me i definitely can see the boundaries of different pixels and since this is a raster each of these different pixels actually have its own value and in this case that value corresponds to the elevation with respect to the mean sea level now in case if you're interested in knowing let's say what is the elevation somewhere around here you can again use this identify tool and you can click on this but make sure that you have turned on dem from here which is the tiff layer and when you click over here you can see that the pixel value is 144. in this case the pixel value corresponds to the raster value which is actually the elevation over here it's about 114 that's 114 meters above the mean sea level and let's see if i zoom this out and from here sort of this stretch of the colors you also can see that the darker areas correspond to lower elevations and the light areas correspond to high elevations so for example if i were to select maybe a pixel from here you see that the pixel value is 62 so that's about 62 meters whereas if i were to select maybe a point from here which is this white color region you can see that the pixel value is 262 which is actually higher pixel value which corresponds to a higher elevation so i think you kind of get the idea of the differences between rust and vector data and if i happen to activate maybe these rivers dissolve normally these rivers are actually falling on lower elevations because usually if you talk about the concept of something like a watershed the river gets formed in the lowest elevation to which the water gets accumulated within a certain uh particular watershed or a basin so that's why you see that along this line of the river normally the pixel value tends to be lower and these are the higher elevations from which actually the water will flow into the river so we can give that kind of a representation to rust data somehow if you're using the the band between black and white maybe the actual variations of the elevations might not be that apparent to you guys so first to get started what i'm going to teach you guys is how to actually do different styling to your rasters so similar to what we did for vector data for us data too we can just go to properties and go to symbology and from here there are actually a couple of choices which we can work with for example if you want to use this stretched option you actually have the possibility of selecting a color ram from here a different color ramp i usually tend to go with this color ramp in which the higher elevations will be attributed to blue color and the lower elevations will be attributed to brown color and if i click on apply you can see that these dark blue areas correspond to elevations of let's say about eight hundreds and these brown areas are corresponding to elevations of uh let's say a negative three zero or lower elevations like that but for some reason if you think that maybe the lower elevation should be corresponding to blue because blue is usually associated with water bodies and lower elevations are the places where the water gets accumulated if you if you think like that you can actually invert this color ramp using this button over here you can invert this and when you click apply you can see that the whole color scheme gets inverted means now the lower elevations are represented by blue colors and the high elevations are represented by those shades of brown now over here one limitation is that the stretch of these different color bands are actually determined by the program for us but let's say if you would like to create a classified image you can divide these different elevation intervals depending on your preference now let's say if i were to select the same color scheme just like this you can now see that it actually groups the different ranges of elevations into different colors over here you can see that from negative 32 up to plus 64 meters you can see that these dark blue colors are actually not just showing one single value but it's actually showing a range of values from 443 up to 879 so this actually takes some detail out from the image because now you don't exactly know what would be the exact elevation because it only shows you a range it could be anything between 443 up to 879. now one way to actually get rid of this inaccuracy is actually by increasing the number of classes let's say if you were to have 22 classes you can see now the intervals are quite high but the the value range is low and now if i press apply you can see that now the picture gets bit more detailed and if i come over here you can see from this sort of legend now these dark blue colors are referring to these very high elevations which actually again comes in between a range from 775 up to 879 well if the unique pixel values are not that important for you then of course this is a good way to go [Music] and again if you wanted to flip the colors in this case actually you don't have a dedicated button to flip the colors all you can do is you can click on this symbol button and you can select flip colors and that'll kind of flip the colors back and let's say if you want to manually determine the intervals by which you specify the range of the elevation you can actually go to this classifier over here and you can manually shift these intervals just like this so these are the different intervals by which your raster will get sort of classified if i may as soon as you make a change over here you can see that the classification method changes to be manual but there are actually quite a few uh automatic classification methods as well uh for example if you specify equal interval you will get the values divided equally in between the lowest and the highest value as you can see over here the gap is equal i mean it might be useful in certain cases or you can use a method like quantile in this case you can see that when we go to the high elevations you can see actually we have a bit of higher gap but the interval is quite low when it comes to the lower elevations you can try that as well and that will sort of create a different picture but always you have to tally what you see over here with this legend that you have over here in order to meaningfully interpret your raster well i i think i prefer to go with the equal interval and i'm going to maybe restrict this only to about 10 classes i think that should be should be sufficient even though i lose some detail because of that so now you can get an idea about how you can actually do different different types of styling but then if you if you would like to retain this stretched option you can always do that as well maybe you can go with a different color scheme as well and we can invert this all right now i'm going to teach you guys how to blend your workflows with raster data and vector data so you can see over here actually the raster is quite huge if i use my measuring tool to measure the actual distance in kilometers you can see the width is about 68 kilometers and the height is about 111 kilometers which is actually massive i do not really need all of this additional information which is present over here so next what i'm going to teach you guys is how to actually clip a raster using a polygon i think you guys remember how to clip polylines using polygons which i discussed with you guys in the first part of this tutorial but now i'm going to sort of isolate only the piece of the raster which is relevant to me not really everything that we might not really need now the things that i might have over here is let's say i have the region of interest parts over here but i feel like i would like to capture this entire area which corresponds to these two rivers as well all right so what i'm going to do is i'm going to actually create a new polygon which encompasses these two rivers i'm just going to randomly create that polygon and after that i'm going to clip the raster based on that polygon let's see how that works out so what i'm going to do is i'm going to go to shape files first and new i'm going to create a new shape file i'm going to create the i'm going to name this one as rust boundary and it's going to be a polygon well this is something important that you need to keep in mind if you're clipping two different items you have to make sure that the coordinate reference system of those two items are same so i'm going to take a step back and i'm going to check what is the coordinate reference system of this raster is if i go to this source over here you can see that yeah the spatial reference is wg is 1984 so if i wanted to clip my desired part just by looking at this graphical interface i need to make sure that i have my corresponding polygons in the same coordinate reference system as well so i'm going to recreate this one which is the rust boundary and it's going to be a polygon and over here now it's not going to be utm zone 30 now it's going to be geographic coordinate systems world wgs 1984 that's the same exact coordinate reference system which corresponds with the with the dm as well so i can click ok after that the same workflow i'm going to let's say i'm going to first remove the fill color and maybe create just a thick outline and after that i'm going to turn this to be on the editing mod [Music] and after that i will select on create features maybe get rid of the catalog for the time being and i'm going to specify the polygon let's say in this manner it's just a random specification of a boundary yeah something like this now we have the polygon all set to go so i can stop editing and save my edits and now i'm going to actually perform the clip operation on this particular raster based on the boundary that i have specified over here so you can do that simply by again opening up the search panel and by now i think you guys can realize that i'm very frequently using the search panel because i can recall what sort of a tool that i'm looking for and i'm pretty sure that after a while if you guys continue to use arcmap you'll be also doing the same all right so i'm going to search again clip and this time since i'm going to cut out a portion of raster i will not go with clip analysis i will go with clip data management and from here you can see that it asks us to specify the raster and i'm going to simply drag this one and drop it over here and i would like to set my output extent to be this rust boundary but very important i have to tick use the input features for clipping geometry even though it's optional otherwise you will actually just get a box with the extents of this raster boundary but not really get the raster clipped according to the exact boundaries of the of the polygon so that's why you have to take this one and then after that you can click ok [Music] well i think i forgot to specify the path to which this this file will get exported if you in case if you happen to forget something like that actually you don't have to worry much either you can do the whole operation again or what you can do is you can simply export this raster simply by right clicking over here and go to export data and from here you can open up the location so i would like to actually put this into this raster folder so i select the folder and click on add and this one i would like to specify the name of the raster to be raster clipped and the format will be geotiff and this time i would actually like to add that corresponding raster to my working space so that i can actually get rid of this dem clip [Music] which we no longer need it's basically the same thing and if you look at the color scales over here you can see this big dm varies from negative 32 up to 879 but this raster clipped which is actually this part the elevations value only ranges from negative 3 up to 374 because it's actually a small region so it's not capturing all of these higher values and even the extremely lower values so i can even turn this bigger dem layer off well i'm going to push this reverse on top of this so similar to what we did i'm going to right click over here go to properties and first make some changes in the symbology i'm going to select a different color ramp well i tend to go with this color ram for some reason even in most of my tutorials so i'm just going to stick with this one because maybe it looks visually pleasing a bit more than others so click ok and again if you would like to check out the different pixel values of this raster you can always go to this identifier tool let me get rid of this one and select once and make sure that you actually select the corresponding layer in this case it's going to be raster clipped so let's see if i select one of these darker red areas it's going to yeah it's going to show me the pixel value about 365 meters above the mean sea level while i come to the sea level and if i check the yeah over here you can see the pixel value is zero so it's basically at the mean sea level if you happen to see negative values in this case actually it's at the mean sea level but if you happen to see negative values that means those locations have recorded an elevation which is lower than the mean z level so mean sea level is basically an average of the of the sea level a long term average which is generally considered as the as a zero point all right that was how to clip a raster so the next thing that i'm going to teach you guys is how to weave a cross section when you have dm like this and you can simply do that using the 3d analyst tool now before doing that you have to make sure that you actually activate your 3d analyst extension you can go to customize and go to extensions and from here you make sure that you have activated this 3d analyst option over here which is an extension all right guys i got rid of all those uh unwanted layers and only retain this rust clipped raster and this reverse dissolve just to get some perspective of the reverse as we can see over here now since you're trying to actually create a cross section we're going to deal with x and y data and it's always good to convert the coordinate reference system to a projected coordinate reference system before we actually proceed on to create the cross section so as you can see over here if i check [Music] still the spatial reference is in geographic coordinate reference system of wgs1984 so i'm going to call the search panel again and from here i'm going to search project raster and the first item you can see that we have the data management project rust option and i'm going to simply drag this and drop it over here and first set the output path i'm going to say raster utm zone 30 north and the output coordinate system will be projected utm 1984 northern hemisphere and zone 30 north yeah i think you can click ok after a while you'll be able to see the reprojected raster and if you check the coordinate reference system you'll be able to see that it's in wgs 1984 utm zone 30 and as you can see over here all right so i'm going to deactivate this raster which was in wgs which was in the geographic coordinate system and let me just go ahead and pull this one up and again yes i have to change the symbology just because it looks a bit more pleasing than the black and white one yes now let's say that we want to create a cross section let's say across somewhere over here so since we have already activated the 3d analyst tool all we have to do is now activate this 3d analysis toolbox and from here make sure that you have selected the corresponding rust in this case it's going to be the rest of utm zone 30 n and after that you can create a line of sight by clicking on this button and let's say my line of sight is going from here up to here so this is actually the line across which the cross section actually will get generated so after you do that make sure that you have selected this and you can click on this profile graph item and now you can see that this is how the profile graph looks so this red color button actually corresponds to this right side and now you can see if the starting point was 0 meters then by the time you reach about 12 000 meters you can see how the elevation actually varies across this profile from the starting point up to the ending point and you can see that the elevation actually varies from about 40 meters all the way up to about 100 almost up to about 160 meters so this is how the elevation actually varies across this so that's how it extracts basically the the raster value which corresponds to each and every pixel which gets crossed by this line of sight and it creates this cross-sectional profile now what i can do is i can actually select this line of sight and delete it and i can create a new line of sight maybe by zooming this one in and if i create the line of sight just like this just across the river you can see that if i create the profile you can see somewhat clearly that it captures the the lowering of the ground level when it comes to the river so this could probably be the the river water level just one thing to keep in mind is that this kind of this is actually srdm data shuttle radar topography mission and they're not able to capture the river bathymetry so what you see as the lowest point is could very well be the water level of the river but not really beyond beyond the water level so that's why you might see a flat line over here so this could really correspond to the water level of the river and you can see that when we go to the other side of the river again the terrain actually rises accordingly so that's how you get the cross section especially when you're working with dem data if you wanted to do a quick visualization and next i'm going to teach you how to actually transfer this information into auxin and create a 3d diagram or a 3d weave of this exact dem because now we are working with elevation data so since we have already activated this 3d analyst toolbar we don't have to specifically open auxin separately through the windows explorer you have this button over here which is the auxin link when you click on that you will see that oxygen will actually automatically get opened so the window of auxin actually looks somewhat similar to arcmap but there are few differences but similar to arcmap you can find your catalog on the right side over here now what i'm interested in is this raster utm 30 zone elevation raster so i'm going to navigate again to the same location to which i have saved that raster and i will drag it and drop it over here just like this and now you can see that when you move your mouse cursor just like this after selecting this navigate tool you can sort of navigate around the dem in sort of a three-dimensional way but you can see the layer itself is actually not 3d yet so now we will see how we can sort of pop this one up based on the elevation values of the raster again if you have the if you're using the mouse you can use the mouse scroll wheel as a button in order to move this to pan this one around or you can simply use this pan tool just to move this around and i'm again going to go to properties and make sure that i go to symbology and similarly similar to what we did before i'm going to select my colors of preference and now in order to activate the 3d properties of this i can go to properties and go to base heights and from here make sure you select floating on a custom surface and after that you can click apply and now if you try to use this navigate tool and try to move it around you will see that things change just a bit but not too much so what i'm going to do is i'm going to go back to properties again and i'm going to increase this factor to convert the layer elevation values to scene units by let's say five just to test yeah now you can see that it sort of vertically exaggerated the the z values and now you can see the clear-cut reverse if you sort of want to visualize this with the perspective of watershed you can see that the water will actually flow into this site and from here the water will actually flow into this side into the river the natural flow path has been carved out from this side as well which corresponds to those two rivers and if you would like to increase the vertical exaggeration maybe about 10 i'm not sure if it's if it'll be too much or not yeah i think it's just just good enough so from here you can actually get a very clear weave of uh how your raster look in a three-dimensional weave as well which can be quite helpful actually just to get a grasp of how your elevation raster might look so this since this is a beginner's tutorial i'm not going to dive much into detailed stuff even with oxy so i'm just going to leave it at this just wanted to show you guys how we can sort of quickly transfer a raster like this to get a 3d weave using oxy while we are working inside arcmap itself so i'm just going to go ahead and close this one out all right next i'm going to tell you guys how to obtain special statistics or zonal statistics using raster data now as you can recall all of these values that all of these colors that we see are actually corresponding to different pixel values so let's say there's a specific region for which you would like to average out all the pixels and you won't kind of get the average elevation value over a certain area now if you want to do something like that if you were to do it manually the way that you would do is would be you pick the pixel value of each of the pixels which falls inside that region you add them all up and then you divide by the number of the pixels which will actually give you the average elevation value but this kind of statistical operations can be very easily done using the zonal statistics tool of arcgis so what i'm going to do is i'm going to first create a search for that tool yeah i'm going to select this sonar statistics spatial analyst tool again you have to make sure that you have activated the spatial analyst extension under this extension option well before that i would like to actually create an area of interest a small area of interest well let me see if i can use my region of interest 1 looks like something like this i think i'll just go ahead and create a new shape file a small shape file a polygon type shape file new and shape file and i'm going to name this one as area of interest and it's going to be again a polygon since i'm going to extract the values from this reprojected raster i'm going to select the same projection of that reprojector raster which is utm zone 30. yeah i'm going to follow a similar workflow in order to create first i activate the start editing and after that i can go ahead and create features from here well this time let me just go ahead and maybe select a rectangle so if you want to select a rectangle over this area this small area yeah i think you can see that now it's done we can go to editor and go to stop editing in order to stop all the edits and now i will go back to this sauna statistics tool yeah over here i have to first specify the zone now my zone is actually this area of interest so i'm going to just drag it and drop it over here and i can select any zone field wouldn't matter much and the raster which contains the values for which i would like to perform this statistical operation is actually this raster utm30 i will drag it and drop it over here and from here you can see what sort of statistical operations we can get now we can calculate the mean the majority maximum medium minimum minority range standard deviation sum and variety so let's say i would like to take the mean the average and if i click ok you can see that it actually creates a new raster and that raster has a constant value which is 52.3851 and that gives us actually the average of all the pixels inside this particular area of interest now similarly if you would like to export that information into a table that's possible as well you can see sauna statistics as a table so i'm going to follow the similar workflow and in this case the input values will be coming from the raster values will be coming from here and since it's a table it actually has option for calculating all of these different statistics not just one so we can just specify all and after that we can click ok and you can see that it actually creates the the table which i can open and weave just like this now you can see again here the minimum pixel value the maximum pixel value the range the mean if you can recall this mean is actually the same average which was calculated just a few minutes ago just like that you can actually get this zonal statistics based on a given area of interest which can come in handy in certain specific applications all right i'm going to flip this back to list by drawing order and the next thing that i'm going to discuss is actually how to convert a raster into a polygon now one of the examples that i can think of is that if you would like to segment this particular raster into elevation groups and if you would like to export those different zones into separate polygons i think you can recall we did some sort of a classification using this classified option where i divided the whole raster into a number of classes and based on this when i click apply you can see that it actually generated different zones of elevation just like this and what if you wanted to export this into a polygon so that you can calculate the area which corresponds to the elevation values ranging from negative 3 up to 48. things like that you can actually calculate if you if you are able to convert this into a polygon well there are other applications as well so now we will see how we can do that so one of the ways of doing that would be to permanently reclassify this raster now even though i did this kind of a classification this is just a classification for the purpose of viewing the raster but the raster itself still consists of individual pixels which forms the entire digital elevation model but if you want to let's say export this kind of elevation segments into into a vector or into into separate polygons what you can do is you can actually use the reclassify tool and from here i will go with the reclasify spatial analyst tool and if i were to input this raster now you can see that the same ranges actually got applied over here but now the new raster values are specified in this manner it just has simple value if you want you can actually change this one doesn't really matter but you will just have to keep in mind that these different values are corresponding to different elevation ranges i'm going to name this one as reclass and just keep in mind that this raster will be a new raster which will sort of group these elevation ranges into these specific new values as you can see over here so i will click ok to export that [Music] yeah now you can see that it generated a new raster call reclass but now if you check the attributes table this is the raster count and you can see that the raster values are just only one two three four five and if you can recall this one is actually corresponding to this elevation ranges from negative 3 to 48 2 is from 48 to 93 3 is from 93 to 150 and so on so this is something that you can actually convert into a polygon now to convert this rust into a polygon what i can do is i can say raster to polygon and you can go with the first tool rust to the polygon and what i'm going to do is i'm going to drag this reclassified raster and now since it's it's a polygon i'm going to open the shape files and say elevation ranges and click ok yeah now you can see that it actually converted everything into polygons now if i open that up you can see that this grid code if i double click on this grid code this grid code number one if i were to select all the number one grid codes you can see that what gets selected over here is actually corresponding to this particular number one which happen to be the elevation values which correspond to negative 3 up to 48 and the grid code of number 2 will be the elevation range 2 which is corresponding to 48 to 93 and so on and if you can recall what we did in the earlier session it would be actually convenient to have all of these grid codes which has the same value merged together we can use the dissolve tool in order to do that so what i'm going to do is i'm going to call the dissolve tool and i will input this elevation ranges and i will make sure that i click on the grid code so that it'll merge everything which has the same grid code into one single polygon now if i open this here now you can see that this is a grid code one again corresponding to this particular elevation range i'm thinking that maybe it would be good to add something like a descriptive column and i'm going to make this a text column and i will add some information about this elevation ranges so i will go and click on edit features and start editing and i will mention that this grid code number one will be elevations from negative 3 up to 48 well i'm just going to ignore the decimal points just for the time being 93 and this third one is going to be elevations from 93 up to 150 and this is going to be elevations from 150 up to 2 to 4 and finally this is going to be elevations from 2 to 4 up to 374 yeah after you're done with everything you can go to editor and stop editing and it'll prompt you to save your edits and if you deactivate everything now and only keep that converted shape file which is of type polygon you can even go to properties and go to symbology and from here if you go to categories you can specify the categories based on specific value field over here now you can either go with the description or you can either go with the grid code it doesn't really matter because even the description and the grid code will be unique for each type of elevation range i'm going to go with grid code and now you can maybe select a color band from here i'm going to maybe select this set and after that you can say add all values and it'll add random values if you don't like these values you can maybe click again you can click until you get the colors that you like or you can manually go over here and actually double click and change the color and i can click apply and now you can again see that this number 1 which corresponds to elevation values from negative 3 up to 48 are represented actually over here and now just because this is a polygon you can do other things which you would normally do with polygons for example if you would like to add the labels you can go to the labels i'm not sure how messy this would be but let's see how it looks if i add the description to be my label apply yeah you can see that well to see the description quite clearly you might have to zoom into your to your area of interest but you get the idea i think i'll get rid of that because it looks a bit messy and not only that what i want to do is i wanted to calculate the area which corresponds to elevations ranging from let's say negative 3 to 48 48 to 93 and so on and now since this is of type polygon you can do that quite simply by creating a new column over here area and i'm going to go with maybe double click yes and now i'm going to say calculate geometry [Music] and i would like to see the area in square kilometers over here just make sure that you select area and it's in square kilometers and when you click ok you'll be able to see that the area which corresponds to the elevations ranging from negative 3 up to 48 is 123 square kilometers 48 up to 93 is 127 so you can see that the mountainous regions ranging from two to four up to 374 it's just only 22 square kilometers which which correspond to these uh brown patches over here all right guys i think we covered quite a lot of things in this tutorial i hope that if you were a beginner at the beginning of this tutorial now you're able to do actually quite a number of things isn't it so that's why i promised you guys that this tutorial will take you to a certain level just within a matter of few hours right now you might be able to do only the things that we did probably that's that's how it is when you're actually learning something for the first time but of course over the course of time you can actually practice and you can learn how we can how you can apply these concepts which we learned to your own specific task and that's how actually you keep on improving yourself to get better at using this software all right now i'm going to head to the final part of this tutorial and that's going to be how to put all of these information into a map now so far what we did was so many different types of geospatial operations but it's of no use if you cannot actually present the story in a meaningful manner let's say to a client of yours or a friend of yours to actually explain the story that you would need to say through your map that's why you need to learn how to actually accurately present this kind of a map to somebody else in case if you need to do that so before i conclude this tutorial i'm just going to show you how how you can create a quick map layout using arcmap and you can export that and once we have done that you can actually export that map as a png or jpeg and maybe you can print that out if you wish to so let's see how you can do that now i'm actually going to present this result which we obtained which corresponds to the elevation ranges as the product that i would like to present to sort of have a filling background i would like to add my base map again so i'll just go over here and go to add data and go to add base map and i will again add the open straight map [Music] just as a base layer now again my story will focus mainly on these different elevation ranges so what i don't want to do is actually to put people's attention into this base map too much so what i will do is i'll just go to properties over here and increase the transparency to about 20 so that the map will still be there but the the amount of attention the map grabs from the from the reader will be actually less so i'm going to maybe increase this up to about 40 percent yeah i think should be fine and right over here at the bottom you will see that so far we were working on this data wave what we need to switch is to the layout view over here so i'm going to click on this layout weave and you can see that well we get the layout view but there are so many things to be adjusted or corrected so the first thing that i'm going to do is i'm going to flip this page to be a landscape page so i will go to this change layout and over here the page sizes i'm going to say i would like to have a a4 size landscape [Music] and after that if you would like to zoom this to fit into the size of your page what i will first do is i will actually drag these corners like this and you can see that we still have some room to sort of zoom this one in so in order to zoom this in you can actually use this zoom in tool and zoom this one in like this and after that you can take the pan tool and you can actually pan it around just like this because i'm trying to leave some space to create a legend over here and maybe add a title over here as well all right i think this should be fine the next thing that i would like to do is maybe i will correct this one from here just a bit [Music] maybe these sides as well yes the next thing that i would like to do is to add a north arrow so i can go to insert and i can create a not arrow from here and you can see that there's a wide variety of node arrows from which you can choose one i'm going to go with this s3 not arrow because it's just a bit plain and quite simple as well just like this and next i would like to add the scale bar so i will go to insert and go to scale bar over here and usually i would like to have the scale bar maybe something like this so of course you can actually check the properties and then see how you can alter the scale bar according to your preference but i'm just going to go with the standards over here and i'm going to select ok and you can see that it's in kilometers and if i if i drag the scale bar you will see that the units also change sorry not the units but the the numbering also changes accordingly well i think i would like to make a bit of a change over here so i'll double click on this and i would like to change the font size to be about maybe 12 and make it bold [Music] yeah i think should be fine maybe drag this one just a bit i think this scale bar should be fine and next i would like to add one legend now in the legend i would like to add only maybe this layer i can go to insert and go to legend and from here you can select which items that you would like to actually add into your legend now over here by you can see by default it selected this particular layer but for some reason if it appears to be something like this you can always select the corresponding layer and push it to the legend items side and i will go over here to next and i will well for the border i will select a line and the background i would like to maybe keep a white background [Music] and maybe increase the gap just a bit and go to next and after that you can simply click ok [Music] all right now you can see that actually the legend is over here but there are a few things which are not really meaningful when the legend appears like this so i would like to go back to properties over here and in symbology instead of splitting this based on the grid code i'm going to split this based on the description and i will say add values like this and now you can see that the description actually changed i will get rid of this all other values because i don't really have any other values and i think this pretty much does it for me if i do not want to have anything over here what i can do is i can click over here once and delete it and that gets rid of this particular description and over here whatever the name that whatever the heading that i would like to add as the layer heading i can just type it in just if i were to rename this layer so i can say this is meters above mean c level something like this now you might think that maybe we might need to change a few things for example increase the font size you can do those things quite easily from here yeah over here i'm going to select apply to class labels and i'm going to increase the font size to be about maybe 12 and make it bold as well yeah you can see that now it got added actually to this part and i will apply to the layer name and maybe change the font size to be about 16. yeah you can see that the layer name got increased the size of the layer name got increased as well just like this i think this should be good enough and finally i'm going to add one title elevation range is based on srtm dem digital elevation model and this title you can drag it and drop it over here of course double click and you can change the properties associated with that particular text [Music] simply by let's say increasing the font size and the font type as well well i'm going to use arial black for that and click ok and apply and see how it fits yeah i think this should be okay for me yeah now after you do everything if you still feel like you want to do some minor adjustments of your map of your base map you can do it simply like this just to make sure that everything is correctly in place all right guys i think this should be it i will try to export this map now so in order to export this map as a jpeg or even a pdf you can go to file and go to export map [Music] and from here i will select the type to be jpeg you can of course increase the dpi value i'll put something about 150 and navigate to the place where you'd like to save your file and i will create a new folder called [Music] map and name this one as elevation ranges and save this and it will take a while to export after everything is done you can go back to your desired folder and you see that jpeg right over here if i were to open this yeah this is how this this is how the map looks quite interesting isn't it all right guys i think that concludes the tutorial we covered quite a number of things starting from the very first part of this tutorial we talked about the vector data how to perform different uh spatial operations on vector data and then we moved on to the raster data and finally we created a beautiful map which is of course in publishable quality depending on the type of the analysis that you actually want to uh present so that's about it for this tutorial guys i really hope that you as a beginner got very thorough understanding of what the capabilities of arcmap are and personally i prefer the style of learning by doing so again i encourage you guys to actually follow the tutorial along from the very first minute until the end following each and every step and once you really acquire that you'll be able to apply these concepts to your own cases without an issue it's guaranteed so thanks a lot for sticking with us guys if you did like the tutorial you know what to do show your support by hitting that like button and comment down anything if you if you really need to get something clarified regarding this tutorial and we'll try to respond as soon as possible stay safe guys thanks a lot and i'll see you in the next one
