[GRASS-user] Apparent missing elevation values

[Crutchley, Simon]

HI Anna,

I only had one map 149683_JJ open, so I don’t think that’s the problem.

I'm new to GRASS. I've tried using my own data and am hitting a problem I don't understand. I've an elevation dataset with values ranging from 36-98m. The histogram shows a range of values. When I run profile analysis it says every point is 45.5m. Screen dumps show my data with the histogram and profile (NFor) as well as that for the test dataset (NCar). Am I doing something basic wrong?


Can we see your region settings, and the elevation raster info?
g.region -p
and
r.info<http://r.info> <your raster>

Could you check that you are profiling the correct raster map? It's not visible from the pictures. In the profile tool, click on one of the first buttons on the toolbar, to set the correct map.
