I need to be able to align utility drawings and maps with the street map/satellite images for our maintenance department's records of electrical conduits, piping and other underground utilities that need to be rather precise. I haven't been able to figure out how to change the viewing angle to be perfectly top-down (nadir) so any maps I import cannot align with the satellite imagery. I have tried using the Freehand Raster Georeferencer plugin to deform the maps after import, but that does not seem to work well for me, and is only a way to skirt around the actual problem. As for CRS, the project originally used EPSG:4269 (the location is roughly near SF California) and tried changing to ERSI:104602 to see if that would resolve the issue.

If I go to maps.google.com, switch to the satellite imagery, and zoom in to where you can see individual buildings, it shows them in proper NADIR view like I need. If you click the little icon that says "3D" on it, then it shifts into a similar projection to the one I have. I don't know how, or if I can differentiate when I import the images to QGIS, but I think that shift from "3D" to "2D" would resolve my issues.

This is my view of the area of my project in ERSI:104602 imported to QGIS with this link I found elsewhere: https://mt1.google.com/vt/lyrs=s&x={x}&y={y}&z={z} (pardon my hasty building shape outlines) enter image description here

    Maps.google uses 3Dmodeled imagery in some places, which gets distorted when zoomed in, i suggest to use a different source for your ortho-imagery like satellites.pro.

  • @HansErren how do I add a different source? I only was able to get maps.google because I found a link that I could directly input as a URL into XYZ Tiles. It doesn't seem like it's quite as simple as: "satellites.pro/USA_map#{X},{y},{Z}"

  • i don't know to directly add sattelites.pro imagery in mymaps, i do know how to screengrab a tile, and georeference it in openstreetmap. where is your vineyard exactly?

  • @HansErren Do you mean basically take a screenshot and import the image to QGIS? If not, could you explain how to screengrab a tile? I'd rather learn how to do it myself.

  • apologies for the confusion, indeed take a screenshot from satellites.pro and georeference it in qgis using the openstreetmap layer from the Quickmapservices plugin.

I had the wrong CRS.

After searching through, and trying several of the WMS services with NADIR imagery mentioned by Vince without significant changes, I tried making a new project altogether and found it was not deformed in my location with ANY of them, even maps.google. I checked the CRS, which had defaulted to EPSG:3857, changed it to EPSG:4269 and it deformed. I changed my original project's CRS to 3857, and it squared out like it should be. It turns out it was a CRS issue, not necessarily an imagery issue (although NADIR imagery certainly helps). I'm not exactly sure why the CRS I looked up that should be for my region is deformed in my region, perhaps someone more experienced could explain, but changing CRS did solve my issue.
