Description
I've researched and it appears that buildvrt is supposed to be able to resolve overlap areas when no data values are defined, but I am unable to produce the expected results.
I've tried the following workflow:
- Set No data values to -999
gdal_translate -ot float32 -of gtiff -a_nodata -999 in_original.tif out_nodata_defined.tif
- Build VRT with specified source no data value
gdalbuildvrt -srcnodata -999 -hidenodata out.vrt out_nodata_defined.tif
Am I doing something wrong, or is this an issue?
