Hi, I'm using GRASS GIS to help me model the Rouen les Essarts race course. One of my aims is to take a nice grayscale image to use in deforming mesh topology.  The circuit straddles two tiles and the shading is markedly different. How can I either fix one or re-color both from scratch based on

This is a common problem (search the list for details) - I have yet to find the source of the problem, but the solution is to set LC_CTYPE in your ~/.bash_profile: export LC_CTYPE=en_US.UTF-8 If you want a different language, you need to know what your language code is. 'locale' might help (o
