I have done something incorrectly trying to create a mask and need a clue-stick to correct the situation. Here's what I did:1. Digitized a line to define an area on a base raster map; saved it as anal_area_mask. 2. v.to.rast in=bndy_conditions type=area out=anal_area_mask use=cat 3. Removed existing mask: r.mask -r 4. Created new mask: r.mask rast=anal_area_mask 5. Selected a raster map in the Layer Manager window. 6. No map displayed in the Map Display window; it's plain white. Did editing the digitized line to an area, and saving it as a line, affect how it was converted to a raster map? Yep. If I change the vector map type from line to boundary or area it is not visible. How do I convert this vector line to either a boundary or area (whichever is appropriate) so it produces a raster mask?
1) Convert the line from type line to type boundary (v.type). 2) Add a centroid inside the area (v.centroids) Moritz _______________________________________________ grass-user mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/grass-user
