Greetings Before I do some "practical" questions I have one "big question", why when I do v.digit a Tcl/Tk digitizer appears instead of the Wxpython digitizer? I'm running it in Linux with a recent grass64svn version?
Now, since I'm using tcl/tk I have some practical questions regarding digitalization. My objective is to create training areas for classification. I didn't find any tutorial regarding of how to use vector digitizer to create training areas. I suppose that I need to create polygons and then add "centroids". Right? 1- First I draw a boundary and close it. In v.digit toolbox I have selected "Insert new record", in layer 1 and Category 3 and Mode "Next not used" When I do "Close line (right mouse button) I get an error window stating: DAtabase table for this layer is not defined". And the same happens for each and every boundary that I define Uhm... WHat am I missing? I mean, what step should I do before? Thank you Best regards, Pedro
