After successfully building the .vrt and translating it to .img, I opened the file and found that the white (nodata) values were copied over valid data. I then tried this: gdal_translate -of PNG -a_nodata 253 file_list.vrt MOD44W.png The nodata value in the map was specified as 253 in the official PDF. Still, no luck. Here is an example of the tiling: http://n2.nabble.com/file/n3720196/tiling.jpg Also, when I checked the .vrt, the size was reported as, '<VRTDataset rasterXSize="91727" rasterYSize="45855">' Now, a 500 meter/px image would be 86400x43200 pixels. A 250m image would be 172800x86400 pixels. The landmask was 231.7m. The reported size was half the resolution of the map! -- View this message in context: http://n2.nabble.com/GDAL-ignores-explicitly-defined-nodata-value-tp3720196p3720196.html Sent from the GDAL - Dev mailing list archive at Nabble.com. _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
