[GRASS-user] raster and vector shift

Hi,

I'm working on some rasters derived from spot images.

When I utilise the command r.to.vect it's work, but I've some trouble about
the display of the rasters.

Sometimes the raster and vector match correctly:

Sometimes there are some problems:

There is a shift.....

Any suggestion?

Alfredo
