What do you mean by manually? I run gdalbuildvrt using the command line, so I don’t understand how it can be done more manually ☺
gdalbuildvrt myfile.vrt file1.tif file2.tif file3.tif file4.tif I have tried using an old version of gdalinfo (1.7.0) and it gives tells me that my first 3 bands in the old file contains a mask flag: Mask Flags: PER_DATASET ALPHA This flag is not present in the 3 new files. Could this be the reason? Btw. my normal version of gdal is 1.9.

Can you check if manually adding the old file works? On Mon, Jul 30, 2012 at 11:01 PM, Casper Børgesen (CABO) <[email protected]<mailto:[email protected]>> wrote: Hi! I’m trying to create a VRT file from 4 GeoTIFFs using gdalbuildvrt. Three of the GeoTIFFs are created using OrthoVista and the last one created with an earlier version of the same program. When I run gdalbuildvrt I get the following error message when I try to add the file created by the early version: Warning 6: gdalbuildvrt does not support heterogenous band characteristics. Skipping... Running gdalinfo on the 4 files I see only a difference in the metadata section (and of course in the coordinates). In the following is the band information from two of the files: [From new version] Band 1 Block=6250x20 Type=Byte, ColorInterp=Red Overviews: 1024x1024 Band 2 Block=6250x20 Type=Byte, ColorInterp=Green Overviews: 1024x1024 Band 3 Block=6250x20 Type=Byte, ColorInterp=Blue Overviews: 1024x1024 Band 4 Block=6250x20 Type=Byte, ColorInterp=Undefined Overviews: 1024x1024 [From earlier version] Band 1 Block=6250x20 Type=Byte, ColorInterp=Red Overviews: 1024x1024 Band 2 Block=6250x20 Type=Byte, ColorInterp=Green Overviews: 1024x1024 Band 3 Block=6250x20 Type=Byte, ColorInterp=Blue Overviews: 1024x1024 Band 4 Block=6250x20 Type=Byte, ColorInterp=Undefined Overviews: 1024x1024 To me they seem identical and I can display them both using QGis 1.8. I guess that the difference is deeper inside the TIFFs than gdalinfo informs me about – what can I do to avoid this problem?
