Hi, I'm working on spatial modeling in population genomics and I'd like to use GRASS for processing & displaying of the world map (in attachment). Unfortunately, I have been unable to accomplish two out of the three things I would like to do:
1. (this one I mentioned in an earlier email, but have not gotten an answer yet) I would like to use the digitizing tool to define regions (represented by different numbers) on the map. However, when I choose a layer and then click the digitizing button in GUI, the monitor that opens is blank. (I am able to edit the blank map and save the shapes I draw. ) 2. I would like to display several 3D points over a flat map of the world (the elevation of each point represents the result of an analysis starting at the particular (x,y) coordinates). For this purpose, I tried converting the raster map into a 3d raster with r.to.rast3d (worked) and then displaying it with NVIZ. Again, I get a blank screen, even though the map was loaded. I can also load the 3d points, but nothing is displayed again. Sometimes, I get the following error: "OpenGL Warning: No pincher, please call crStateSetCurrentPointers() in your SPU" I was able to display the example Spearfish data (elevation + rivers+roads), though. Can you tell me where I'm doing a mistake? Cheers, Anna p.s. I'm using Debian Linux on a VirtualBox in Windows 7.
