Dear all, I'm having some trouble copying the values from a raster image (Dartmoor1) to a series of vector points (Contour_points - created from a contour vector map). When I try to use v.what.rast I get the following error:
v.what.rast vector=contour_poi...@permanent raster=dartmo...@permanent layer=1 column=level More points (644858) of category 1, value set to 'NULL' 1 categories loaded from table 1 categories loaded from vector 0 categories from vector missing in table 1 duplicate categories in vector 1 records updated 0 update errors I think that this is an attribute table issue. I have followed the instructions in Example B http://grass.itc.it/grass62/manuals/html62_user/v.what.rast.html but get the following message v.to.db map=Contour_points option=cat Reading features... Updating database... 1 categories read from vector map (layer 1) 1 records selected from table (layer 1) 1 categories read from vector map exist in selection from table 0 records updated/inserted (layer 1) Record (cat 1) already exists (not inserted) I have also tried creating and attaching a new table but get the same result for v.what.vect. Any ideas welcome, thanks for reading! Rebecca
