Study area Map using QGIS | Study Area Location Map Preparation | QGIS for beginners - Tutorials |

[Music] hello friends welcome back to our channel and in this tutorial i am going to demonstrate you how to prepare a study area map for a particular location before getting to this video make sure to subscribe to our channel for more updates on gis related videos so let's get started i'm just going to demonstrate you how to prepare a study area map in qgis software so this is an open source software which can be used by anyone so now we need different datasets i have opened qgis platform we need all the administrative boundaries for preparing a study area map so i will just show you different sources from where we can download our administrative boundaries so there are different sources from which we can download our administrative boundaries the first one is diva gis you can see free spatial data click on free spatial data once you click on free spatial data you will find an option called country level data go to country level data and you can find different countries whichever country you want you can actually like download the data for example if i need it for us you have to select newest and you will you have to select us you will get different layers you have to go with administrative layers and in case if you are working with indian conditions then i have actually like provided a link in the description below where you can get the updated shape files so this is the location where we actually have all the updated shapefiles what you can do is just click on this code and you'll find an option called download zip you can just click on that and you can download the data in case if you want to download it for some other location just select the administrative boundaries and you can simply click ok and you'll get an option to download it once you click on this download the data will be automatically getting downloaded so these two sources are mostly sufficient enough for downloading any of the datasets that is required for the preparation of our study area map in case if you have any mismatching with the boundary which is present in this particular website what you can do is like you can go to your country's official website and you can download the data so now as you see we have downloaded the data you can extract the data out so we need to choose a particular location for the preparation of our study area map so in this particular example i am going to go with the kodahu district of karnataka as the example so first we can see here there are like different json files either you can make use of this json files or inside each state you will actually like find sorry inside each folders you will find this shape files and as far as district is concerned you will find for each and every district you will find different gpkg files so the first thing that i am in need of is the indian state boundary so i'm just opening the indian boundary over here in qgis so this is the updated indian boundary and next i have to open the district boundary so i'm just focusing on cordova district of karnataka so i just need to go to karnataka so this is the shape file of uh this of the karnataka districts so as you can see this is actually our kodaku district so for this i'm going to prepare a study area now we can see like the i have i don't when i started i didn't have any layers but right now i have two different layers the one is the indian boundary or the indian shape file that is for the entire country and next is the karnataka state so what i should do next is i need to extract different features for example like this is uh the district uh shape file of entire karnataka what i need is i want only kodagu district so what i'm going to do is i'm just going to select click on this select features by area and i'm just going to select this kodagu district once i select this protocol district the particular feature alone will be getting highlighted in invoker and after selecting it what you have to do is go to the particular shapefile in this layer click on export and you will find an option called save selected features what you have to do is click on the same selected feature as you will find an option where to save it going to create a folder here this is going to be file so i'm just going to create it over there so this is district boundary so please make sure in this encoding there will be an option called save only selected features i have to extract only kodagu so i'm just clicking on i'm making sure that this is enabled and then you can just click on ok now if you see i just extracted next what i should do is i have an entire karnataka but the thing is like it is having all the districts but i need only karnataka for my purpose only the boundary of karnataka so what i'm doing is i'm selecting karnataka first i have to select the layers in my layers panel then i should select karnataka and i should follow the same procedure so now i have entered the name i'm just clicking on save yeah so now what i have done is i have created this layer of like i have extracted karnataka alone i have extracted kodaku district alone so this is our podago district and now i have this india map and as far as tamil nadu is concerned in this particular location we have some polygon issues what you have to do is you have to like modify or you have to edit it and you have to rectify all these issues these are some gaps which has to be activated but other than that we have all the data which is required right now the first thing is i have an india entire india shape file i have it with me right now and the next thing is i have my karnataka state boundary alone next i have recorded what i should do next is i have to focus only on photography when i am preparing a study area map what are the features that should be listed on quran that i should make a note of it so when it comes to this particular data i should like list out all the road network i should list all most of the important places and there will be like other features which i might have to represent so basically like uh when it comes to representing features what we'll do is like we will mention at least the important places that are present inside this particular district other than road network if you have to mention the road network then that's fine but still in some cases at least like we'll mention the important places in case if you want to download the places we have a separate website for that which is pasted in the description you can check it out so this is a particular link where you can download the building's information land use information natural features places point of interest railways highways and water bodies so what i'm going to do is i'm just going to download the important places alone so i'm just making sure i make a single click once i'm done with it you can actually like go and you can copy this file you can extract the file as a separate folder and if you open that particular file in your qgis you can see that this particular places information will be provided for all over india what i need is i want only the information for kodunk what i will do is like you just have to go to vector in jio processing tools you will find an option called clipboard select clip so you should select the input layer and overlay layer the input layer should be the places and the overlay layer should be our karnataka sorry kodagu district boundary once you are done with it provide where the information has to be saved and then you will find the clipped feature so now i got the points if you see in this particular location i have so many points i don't need these many number of points if you just open the attribute table you can find all these informations so this means is county that means like it is representing the entire district we have towns villages and other stuff we actually like we don't need villages so i'm removing the villages out this is in a local language so i am removing it out i am removing the kodagu like a district and other than that spools are not required i feel like junction is also not required other than this like i feel medicare is required since it's a town it is required that's selected already but all the other informations i have actually like selected what i'm going to do is i'm going to delete all these features now if you see i have 11 places and if you check in this particular map it was like approximately distributed and in here i'm just removing this particular point and this place also i'm reviewing both the points okay now i guess like this will be like a better representation of my particular study only these places are the major places i'm just clicking on save and now yes i'm done so these are the places that i have to actually make mark in my particular map so what i should do now to name all these points so i have to go to properties and in properties like we'll find symbology so whatever the symbols that you want we can actually give it i'm just going to give a red dot to it if you want to change the size of that particular symbol you can change it over here making the necessary changes and then i will go to labels i'm just just going to give the column name that is named as my particular name that has to be displayed or the labels that has to be displayed the font i'm giving it as times new roman whatever the size you want you can actually give it formatting buffer please make sure to give buffer only then it will be like kind of appearing i'm done with all the modifications you can just click apply and okay now this is how my names will be displayed now so this is like kind of so big in this particular image so you know we don't have to actually like worry about it what we can do is we have to like x we are going to export it as a map so we should actually like focus on how it will appear in a map so we don't have to make any modifications right now let it key let us keep it as such and now i got the points what do i need next few might be like interested in road networks and other data sets but in my case i am actually in need of a google earth image for this particular study area so what i am going to do is i am just going to go to web and you will find an option called quick map services in case if this option is not present in your system what you have to do is go to plugins go to manage and install plugins click on it you will find an like the manage and install plugins toolbar will be like appearing over here what you can do is you can search for quick map services once you like install this quick map services you will find quick map services under your web by default all these layers won't be listed in your panel what you have to do is you have to go to settings and in settings you will find an option called more services click on that more services and make sure to click on this get contributed back once you click on this get contributed back it will be like there will be an option called text req all the packages has been successfully installed yeah you can see here latest version of contribution pack was downloaded you can just click ok and you can click on save now if you go to web band quick map services you will find an option called google i am in need of google image you can go with esri data or you can go with bing maps whatever the data it is required you can go with it i am going to go with google satellite image so this is the satellite image of my kodaku district what i am going to do is i am just going to export the image that is shown in the screen and i'm just going to crop your reference this particular image and then i'm going to like crop it for my particular location once i say that i'm going to jio reference it you might feel that that is a huge task but as far as qgis is concerned we don't need any universal map downloader or we don't need any other fine it's there like tools like lcl gis to download the data what we can do is i'll show you very simple procedure go to project just open your satellite image and don't open any other images just open only your google image go to project you will find an option called import bar export go to export map to image okay so by default you will find one window and you will see the extents and other stuffs you don't have to disturb anything if you want you can change the resolution to 300 other than that you don't have to change you don't have to make any modifications just click on save it will ask you where to save it go to desktop and you can save it now you can find it is actually saved in the name of college i'm just going to remove my satellite image right now that is the google satellite image what i am going to do is i am going to open the console raster layer so you can see here this is the college tiff that i have actually downloaded since i have named it as college so this is a google earth image you can see in the coordinates box this is actually geo referenced and if you zoom in and zoom out or if you place your particular boundary over it it will be actually generalized you don't have to make any changes just by clicking and exporting it you will get a google image that is geo referenced now i have to like clip the data for my particular study area alone so what i have to do is raster when you have to go to extraction you will find an option called clip raster by mask the input is going to be college and the mask layer is going to be kodaku district it lost for source and target projection by default that is 4326 selected that's fine if you do not select culture that is fine i am going to go with four three toes exposition only that is geographical coordinate system projection so now i'm saying it does codago i just renamed it the proper way so now if i click on run you can see that now my output will be exactly extracted google earth image of this code of district so this is what i need in this particular place so now i have the places over it and next i have my cordago district boundary what i want this i want a hollow boundary so i'm going to change it as in the solid fill i'm going to make it as no brush i am going to extend the thickness of the particular line network so now if you see here at the edges you can see the black colors and it is like clearly finished out and this is my kodaku boundary right now this is the study area that i am going to prepare right now so when it is when it comes to study area basically what we'll do is like we'll have one india map will have one like karnataka map and then only like we'll show our kodaku district so for that purpose what you have what you have to do is you have to select all the layers that is only those layers should be enabled in the layers panel and if you go click on this i button in your layers that is the third option you will find an option called add theme select this add theme and this should be so i'm going to name it as kodagu this theme is going to be so now i have created one theme and the second theme that is like now the main map content is ready so the second content in the bottom is going to be my indian state boundary or like you can say indian entire boundary of india along with its state and i also like to have karnataka in it so if you go with the colors i'm going to change the colors out so i'll go with some kind of like some few light colors and then i'm going to go with for cordova i'm just going to go with some light blue colors or i'll go with some pinkish colors yeah so now i would i am able to like differentiate it so this is going to be my second layer that is entire indian this is going to be the india stuff and after this i'm just going to have a third map that is going to be my kodaku district boundary so what i have to do is i'm just going to duplicate this layer because i need one more boundary of kodaku so i'm just going to duplicate it and karnataka is also like i'm going to duplicate it so these two layers are going to be my third layer and for this i'm just going to give another color so i'll make sure to give something here yellow one maybe like i'll go with blue color for this i should make sure to select this since i have selected this more brush over here i'm selecting solid yeah so now this is my [Music] cordova boundary as you see it's very clear right now and this is going to be my third layer that is for karnataka so now i have created three different themes all my layers are ready so the first thing is this is going to be my indian layer and the second is this is going to be my kodaku are the main content of my map and the third is going to be for karnataka so now i have prepared all these required layers or like the required three maps i just prepared it out what you have to do next is click on project you will find an option called new print layout click on new print layout type whatever the name you want study area once you click on the study area you will get this particular window in this particular window pin comes to any sort of maps there are like certain components that are mandatory so we will list one by one so in qj is in your layers funnel if you go under items sorry if you go under add item you will find all the details so i'll go one by one the first thing that i'm in need office i need a map so i'm just going to create this particular map over here i will be like actually in need of three different maps because one is the main content of kodagu and the next two are going to be one is for india and the next is going to be so i'm clicking on admin this is going to be for entire india and this is going to be for karnataka so yes so now it's done so i have like created the layer like i have imported the map but still only like i'm seeing karnataka so what should we do for that in item properties you will find an option called layers over here if you click on this i button you will find three different options which we created and go to this move item content option if you just zoom in you will get the portable map that is required for your location so i'm just adjusting the zoom size so that it would match perfectly to our requirement so this is what i need right now maybe like i'll make it as something around 55 so this is fine so first i preferred my uh kodakuma so the next thing is i have to get my india map here so i'm going to put india i'm just going to use map item and as far as karnataka is concerned i guess the content is proper only thing is like you should modify the main contents of the size once this is done now we have all we have all the maps what we have to do is any different frames because like it is not kind of looking good so what i'm going to do is i'm just going to add frames for all these so now if you see i have added frame now this is this kind so kind of like looks like a map but still we should beautify we should add all the required datasets or like required stuffs like there should be latitude longitude there should be a north arrow and that should like all the other requirements so what i'm going to do is i'm i'm going to like reduce the size of this map to some extent so that like i will be able to add all the content inside it let us make it as six yeah this will be like fine so that i can add all the necessary content inside it now the first thing that i have to add is the north or like let us add the north earth for adding a north arrow what you have to do is go to add picture select the location where you need the north arrow to be placed you will find different symbols if you just scroll down over here you will find different north arrows out of which you can select any one of the north arrow i am going to go with this particular block so now once you click on that the north arrow will be placed over here so now the north arrow is done the next one which i am in need office i'll like focus on the on creating grids for this particular map i don't need grid for these two because it can kind of become clumsy whereas for this particular kodaku district alone i definitely i am in need of my particular latitude and longitude so for adding latitude and longitude what you have to do is go to grids in grids option you will find an option called add a new grid enable it select the grid one and then you will find an option called modify grid click on it now you will get a list of data that like list of stuffs so it will last either it is a solid line cross mark markers or frames and annotations only i prefer going with frames and annotations often but in case if you need you can go with solid line also i'm actually giving the limit as 0.5 degrees so this kind of kind of like workout works out well for me offset so that like um kind of like matches uh exactly to my requirements just giving a normal offset just go to the grids i've given all the offsets now i'm just going to go with frames and annotations only that means only the values will be listed at the corners and in the frame it will ask you what type of frame you need either you need a zebra card or you need exterior ticks only or interior text or line border it will ask you i'll let go with the exterior right now maybe like zebra cut is one thing which will be like um easy for like impressive but i am going with exterior ticks and if you scroll down you will find an option called draw coordinates click on the draw coordinates and you'll find the latitudes and longitude listed and when it comes to the format you can select degree minutes seconds as the format and then in the left it is horizontal so i'm making it as vertical ascending and in the right i am making it as vertical so that the values doesn't look clumsy if you scroll down to the bottom after this coordinate what is the total number of precision required i am selecting the precision as zero and we can also choose the font i'm actually choosing the font as times new roman i'm going to give it as gold font size 18 will be fine so now i created grid grid is actually done what next we need to have a scale bar so for adding scale bar like we have a direct option first what you have to do is select the map window if you select india map or this is actually mapped to if you select map to then for that particular window you will get your skateboard so what you have to do is whatever the maps that you want your scale to be priced click that and then go to add item add scale just make a single click your scale bar will appear over there so this is your scale bar and if you see in this main properties it will show for which map it is appearing you can select double deck boxes or single click boxes whatever it is you can give whatever the segments that is record also you can make use of it so now i have inserted my scale bar what do i need next maybe like if you want to add a title over there saying that this is portable district so i'm just clicking on this add item you can find the add label make use of it so font i'm making it just so now i have given my title also the only thing that is left over is my legend so to add legend go to add item you'll find an option called add legend you can click on it where you want your religion to be and then click ok your legend will be automatically listed which holds all the data that are present in our qgis window what you have to do is you have to click on this auto update option and you can remove all the data that is not required so in this particular place i need the clip because those are the places it is named as clipped i want to change it out so i'm changing it as clicking on the pencil button and changing it will get changed so this i'm not in need of it i'm going to remove it i'm not in need of it i'm going to remove it i don't want that all the other stuff i need what i'm going to do is this is india's state boundary which is present over there i'm going to make it as india indian okay i'm going to make it as indian boundary next for this i'm going to make it as karnataka boundary okay this is not the exact color so removing it i can actually like copy the name because you can see that karnataka is actually present in some other colors so now all my labels are like done perfectly the only thing is like i just need to have a title of this called as legend and maybe like if you want you can add a frame to it and also like if you want you can change the fonts also title means that is going to be the legend so for that i'm changing the title as like to font times new roman 90 and you will see like groups of group items so all these things are going to be items i'm going to change the font size for those two so this is the font size so once i made it bold you can see how it got expanded so based on that we can actually rectify our stuff in case you feel all these things are like closely packed what you can do is you have an option called spacing over here you can actually like arrange the spacings so based on that whatever it is you can actually like modify it now i have my legend over here i'll actually replace it somewhere in here because i have a map now i can move my map to some extent now i guess like we have our study area ready if you want like you can move your medicare over here and also like you can move all this legend box towards this edge and your scale towards here this will also kind of work out so it's all about beautification so whatever the beautification that is required we can actually like beautify it so now if you see very clearly like i have actually created a proper study area map whatever the thing that has to be present in a map is present over here and now we have to export this particular map so to export it what we have to do is go to layout you will find an option called export as image export as pdf export as svg to export it as an image just click on export as image you will be like able to like export it as your own image by default make sure it is in 300 dba so that it will be of good resolution okay now we got the message saying that like the study area is successfully exported if you go and double click on your study area so this is our study area and you can find how could we actually created our study area and if you like this video make sure to subscribe to our channel for more updates and in case if you are in need of any specific tutorial please make sure to comment in
