I have three raster images within a similar region

enter image description here

I'd like to combine these three rasters into one raster image using QGIS or any other open-source method, and where there are gaps just set as a nodata value.

Is this possible?

    Did you try QGIS with Menu raster > Miscellaneous > Merge or Build Virtual Raster?

  • I've tried both and keep getting this error FileNotFoundError: [Errno 2] No such file or directory:"C:/Users/Amy/AppData/Local/Temp/processing_JazlHT/47c0fba9c2bc48d08f0f007800ddb36a/buildvrtInputFiles.txt" Sep 19, 2022 at 18:51

I sometimes have difficulties merging files with the merge algorithm when:

  • files are not tiff files, converting to tiff first could help
  • files do not include projection, converting to tiff first with projection could help
