Description (last modified by jaerobbo)

I've researched and it appears that buildvrt is supposed to be able to resolve overlap areas when no data values are defined for the sources, but I am unable to produce the expected results.

I've tried the following workflow:

  1. Set No data values to -999 for rsters

gdal_translate -ot float32 -of gtiff -a_nodata -999 in_01.tif out_01.tif

gdal_translate -ot float32 -of gtiff -a_nodata -999 in_02.tif out_02.tif

  1. Build VRT with specified source no data value

gdalbuildvrt -srcnodata -999 -hidenodata out.vrt *.tif

Am I doing something wrong, or is this an issue?
