Hey
Not necessarily. It is also possible that GCPs are stored and gdalwarp
needs to be
used first to obtain a really geocoded file.
Say, use gdalwarp to preprocess the data. Please try with one channel and
post what gdalinfo reports on the resulting file.

This morning I noticed very odd output from v.voronoi, specifically on split

Number of primitives: 27

Number of lines: 0
