Description (last modified by )
Currently gdalbuildvrt doesn't set the "relativeToVRT" attribute correctly when the output vrt is not in the same directory that the command was run from. e.g:
$ gdalbuildvrt ../test.vrt test1.tif test2.tif $ cat ../test.vrt <VRTDataset rasterXSize="250" rasterYSize="500"> <GeoTransform> 0.0000000000000000e+000, 1.0000000000000000e+000, 0.0000000000000000e+000, 5.0000000000000000e+002, 0.0000000000000000e+000,-1.0000000000000000e+000</GeoTransform> <VRTRasterBand dataType="Byte" band="1"> <NoDataValue>0.00000000000000E+000</NoDataValue> <ComplexSource> <SourceFilename relativeToVRT="0">test1.tif</SourceFilename> <SourceBand>1</SourceBand> <SourceProperties RasterXSize="250" RasterYSize="250" DataType="Byte" BlockXSize="256" BlockYSize="16" /> <SrcRect xOff="0" yOff="0" xSize="250" ySize="250" /> <DstRect xOff="0" yOff="250" xSize="250" ySize="250" /> <NODATA>0</NODATA> </ComplexSource> <ComplexSource> <SourceFilename relativeToVRT="0">test2.tif</SourceFilename> <SourceBand>1</SourceBand> <SourceProperties RasterXSize="250" RasterYSize="250" DataType="Byte" BlockXSize="256" BlockYSize="16" /> <SrcRect xOff="0" yOff="0" xSize="250" ySize="250" /> <DstRect xOff="0" yOff="0" xSize="250" ySize="250" /> <NODATA>0</NODATA> </ComplexSource> </VRTRasterBand> </VRTDataset>
The obvious workaround is: gdalbuildvrt test.vrt dir/test1.tif dir/test2.tif but I often forget that :) so requesting an enhancement to handle relative paths better.

Hi,
So your image files are /dir/test1.tif and /dir2.tif and you write the vrt file one level up in the directory tree? What do you want to happen then? Is it like this
<SourceFilename relativeToVRT="1">dir/test1.tif</SourceFilename>
What if you are in Windows your working directory is for example d:\data\satellite_images and you decide to write the vrt file into c:\data\vrt_files as
Relative paths can't work in such case. I would say that you had better make your vrt directory as your working directory and run gdalbuildvrt from there as
You call it workaround but I would call it the right way to do the job. However, I may have misunderstood your goal.
