I am trying to reproject and retile BMNG data. So far I have processing my images into geotifs. I can view them together in QGIS and everything looks good:

enter image description here

I then created a vrt file. The vrt file lives in the same folder as the tifs. When I attempt to open the vrt in QGIS or run gdalwarp on it, I get the following error: ERROR 4: \1_3.tif: No such file or directory

The lines in the vrt that reference the offending tif look like this:

<SimpleSource> <SourceFilename relativeToVRT="1">\1_3.tif</SourceFilename> <SourceBand>1</SourceBand> <SourceProperties RasterXSize="512" RasterYSize="512" DataType="Byte" BlockXSize="512" BlockYSize="5" /> <SrcRect xOff="0" yOff="0" xSize="512" ySize="512" /> <DstRect xOff="1536" yOff="1536" xSize="512" ySize="512" /> </SimpleSource>

What am I doing wrong?

If your tifs are actually named "1_3.tif", not "\1_3.tif" then you need to remove the backslash.

<SimpleSource>
      <SourceFilename relativeToVRT="1">1_3.tif</SourceFilename>
      <SourceBand>1</SourceBand>
      <SourceProperties RasterXSize="512" RasterYSize="512" DataType="Byte" BlockXSize="512" BlockYSize="5" />
      <SrcRect xOff="0" yOff="0" xSize="512" ySize="512" />
      <DstRect xOff="1536" yOff="1536" xSize="512" ySize="512" />
</SimpleSource>

  • Thank you! It turns out I was running gdalbuildvrt with <output_path>*.tif and I had an extra backslash.
