I got several Raster Layers as Digital Surface Models (DSM) in QGIS. I now want to merge them by using Raster -> Miscellaneous -> Merge
, but if I do, the resulting merged raster layer is just blank space, as seen in the picture below. Does anyone know what's the problem here? Changing the data type doesn't d anything, I used float32. I also tried merging only two, also didn't work...
UPDATE I got it working just fine by using Raster -> Miscellaneous -> Build Virtual Raster
but I'd still like to know what's the problem here...
As requested, Does the gdalinfo
forvirtual raster have any disadvantages vs the two input layers:merged one?
