 Hello, in this video you're going to learn how to verify if a georeferenced map or any layer that you've received is in the correct location with the correct projection. You can simply click right on a location and print the coordinates here to the screen. The map CRS are the coordinates in the projection of your project. In this case we can compare those coordinates with the ones printed here on the side of the grid that we used for georeferencing. Let's take another spot. So we simply click right and there we can see the coordinates. We also see the coordinates in WGS84, which is in latitude-longitude coordinates. Besides checking the coordinates, we can also add base maps. And the very useful plugin for that is the Quick Map Services plugin. So here I'm going to install the Quick Map Services plugin from the Plugins Manager. The plugin adds an item under the web menu and you can see that you can add a few layers, but if you go to Settings then there's a tab with more services and you can click there on Get Contributed Pack to add many more of these base maps. If I go back now to the web menu I find a longer list, including Google Satellites and SVM Bing layers. Let's use OSM Standard as a base map to compare our georeferenced topographical map with. We can simply switch it on and off, but that's a bit hard to compare. You can also go to the Layer Styling Panel and play with the transparency. Go here to the Transparency tab and then we change the global opacity. That already gives more information and it looks like the georeferencing is quite correct. A great feature of QGIS are the blending modes. If I choose Blending Multiply it will combine both the topographical map and the OSM Standard layer. And here we see that it's a nice match between the two. Let's try it with another layer. Now we'll use the Google Satellite layer. I have to switch off OSM Standard because it was on top of the Satellite and the blending of the topographical map is still on. So we mix both layers and also there I see that there's quite a nice match. Now there's this little black border which is caused by no data values that were added by the projection of the topographical map. So I add this additional no data value of 0 and then all the black areas are transparent. So this is how you can check if any layer that you have downloaded or georeferenced is in the correct location by using base maps.
