I try to find a way to create DEM model for two overlapping images from different sources. The upper image has transparency of 50% and as you can see they don't quite overlap correctly. The projections are adjusted correctly (EPSG:3006 - SWEREF99 TM), but they still look this way.

Why is this happening?

I am new to QGIS and GIS in general.

overlapping images

  • How did you adjust the projections? – MrXsquared Nov 24 '19 at 14:25
  • I tried both in properties (Set source CRS) and Raster->Projections->Warp.. but neither helped - the image remained the same – Marina Kolpakova Nov 24 '19 at 16:18
  • Do not use Set source CRS. This does not reproject your raster. Reset it to its original projection. Warp should actually do it then. If not, whats the source of your raster? – MrXsquared Nov 24 '19 at 16:35
  • One image is from DigitalGlobe and another one from Lantmaterialet (Orthophoto) - lantmateriet.se/en/maps-and-geographic-information/… - I used QGIS to merge several photos from the last one – Marina Kolpakova Nov 24 '19 at 16:45
