Download and georeference Google Earth images in QGIS 3.1 with Quickmap Service Plugin

I'm a hydrogeologist my model alive is think out of the box my name Marcel my experience gram water and soil contaminations I'm the creator of jail our TV a channel of geographic information systems GIS geology hydrogeology and contamination the purpose the objective the goal the intention the target the desire share my experience unacknowledged to any point of discussion the gel LGB community promote the use of free and open-source offer a free digital society provide technical advice to environmental companies and opportunity for professional growth [Music] [Music] hello guys and welcome back to my channel in this occasion I am going to show you how to get to referring to the high resolution images using quantity is version 3.12 for many years who was using external somewhere to get your reference images lives as planet but today you are going to watch a method where it's very easy and fast to obtain images with coordinating Kulik only using one to gif also I'm going to use the three software Google Earth and Open Office okay let's go to do it the first step is download the equipment plugin to do that one we need internet connection we have to go here to plugins - uninstall plug-in and then here in search just right we click map service is this plug-in here so the plug-in and install close here in whip as you can see we don't have too much maps even we don't have Google Earth in these options then to get all these maps we have to go settings go here to more services and then click this button here you can check this website here safe and now as you can see we don't we have all these servers with them ups then the one we are going to use for this example is going to be Google and it's going to be google satellite the second step is to select the map and array you want to download in this case then the map is going to be the google satellite and the area first I'm going to show you the area with Google Earth I am going to download gas station located in Hungary concretely in Budapest is this gas station here and to search the gas station in quantum GIS we are going to look for some points of reference for example the morphology of this we were here also it is important to see that in Google Earth we can see the coordinates the coordinates are here they are in UTM and you can see the Sun in this case is 34 T ok let's go to look this gas station in quantity is let's go here web web map services and select the map you want in this case is satellite to make easy the location we can lot on hybrid map just get to do it with map service Google Earth hi grid and here we can look for Hungary here Budapest and as I said before we have to look for the morphology of the river in this case is this river here and the location of the gas station is over here is this gas station and we can change the map again one important thing to know is I didn't change any reference coordinate systems I'll leave the 1 by default is this one wgs84 cellular Mercado and I didn't change that one because when we load this kind of maps we are taking information for us server and if we change the coordinates then the information is going to to come very slow and it's going to take a lot of time to plot all the map right then the best way to work with this kind of maps is justly if the the coordinates by the fall and when you have your area is when you have to to put here the coordinates year one and that one is going to be the third step now we have to decide in what coordinates we want to download the image the coordinates we put here is the coordinates we are going to have in our image as we saw before at the Google Earth image over area it's located at the UTM some 34 T was good to look for that one here to change the coordinates because what I want is a projected coordinate systems I'm going to use also the wgs84 okay then let's go to look for that as on 34 yes right here that will get s 34 and then we have to look here for the coordinates with is this one here wgs84 UTM 734 north as you see when you select that one here is going to change and is going to indicate what is the area for these coordinate systems okay then press apply okay and now the coordinates change for this one the fourth step is open the algorithm mm just go to here processing toolbox and sell it raster tools and the algorithm is going to be converted map to raster click here double click here and now let's go to add these parameters [Music] first let's go to add the extension of the image select the second option here is going to be something from here this area this one are going to leave fly Darwin this one also and here is going to be the resolution for the image 0.01 it's enough you are not going to get a better resolution then select here the layer you want to render so here allow you to render in this case is going to be google satellite okay and here select the folder where you want to save the image you are going to download save to file in my case I'm going to save here at the desktop and is going to be a follower coal gas station [Music] image save and run run the process now the process is complete close and as you can see here we have our image is this one here and if you check the properties of this image and go to the information you are going to see what is the coordinate reference systems for this image as we said before is wgs84 UTM zone 34 north and it's a projective system okay now we have our image geo-reference if we go to the file that it's a tiff image and that does it one of the inconvenience of these methods could be sometimes located your site in this case it was not very difficult because it was a big city and you have a lot of elements that you can use as a reference to locate your site but sometimes it could be very complex if you are working in a remote location and there is no too much elements to recognize your area now I'm going to show you a technique that you can use to to get your site very fast but first let me tell you that if you are new in this channel and you like this kind of content consider subscribing don't forget to like share this channel with your friends if you have comments please leave them below I love to hear from you and if you have any suggestion for the uncommon videos I love to hear those too okay now let's go to see the technique let's go to suppose that we have found all a gas field located at the province of Alberta in Canada and we want to get the geographer and Google Earth high-resolution image for this side this side is here as you can see in this area the there is no too much elements that we can use to locate our area manually then in this case we are going to take the UTM coordinates to locate our side on quantum GIS to make this one make sure you have UTM coordinates to do that one just go here to options tool options and make sure you have Universal transverse Mercator option click OK then click this option here then you can move the pink over here as you move the pink the coordinates are changing here okay the information we need to know is the zone in this case is 11 3 the coordinates for the Easton and the coordinates for the northing then we have to copy this coordinate am page in an a spreadsheet to create our spreadsheet we are going to use the three an open-source software Apache Open Office is this one here it this one it's pretty similar to Microsoft X okay then we have to create a couple of columns one is going to be for the eggs another one is going to be further Y then we have to copy and paste the coordinates x is going to be for the extent and y is going to be further north in it is very important to save in a specific format in this case we want to save this one as a call for coordinates and is going to be this format here text CSV save keep current format and this options are K okay and okay then we can close this one go to quantum GIS first we have to do in in this order that is important first we want to load a map that's a line because we don't want to change the coordinate reference systems we want this one by the fall and then we can load the spreadsheet we create it then click here sorry first you have to make sure that you have this option the limited test okay go here select your file okay this option is good and then in geometry this option here you have to make sure that you have this option selected for the fields X you have to select the column with designated as a Peaks and for the wide the same okay then you have to look for your current in existence I did already this is wgs84 eutm son 11 okay you have to look for your coordinates here look here and then select the one you want this case is this one as you can see this this one is covered this area okay and add and close then as you can see we have two point there just click right zoom to the liar and then you can Maysoon until you get your your field okay is this Phil here and that's it that's the technique you can use to locate your sites very fast and easy then you have to follow all the steps we did for the gas station thank you very much for watching this video I'll see you on the next one [Music] [Music]
