I made some contour lines with r.contour. AFAIK, these are vector lines. But I cannot edit them in the digitizer. When I click on a vertex, nothing happens. I can make and edit other lines, but not contour lines. No error in the console either. Anyone know why?
I'm using GRASS 7 compiled yesterday. Michael ____________________ C.

But anyone can tell me how the transformation works if a pixel P1 has value X after i.pca it will be Y Is there any specific math equation that is applied to every pixel by PCA? For sure. There are two _good_ grassy-sources to start with: 1. the i.pca's manual http://grass.osgeo.org/grass70/manuals/i.pca.html 2.the GRASS-Wiki page explains all one needs to know -- even if it requires some clean-up <http://grasswiki.osgeo.org/wiki/Principal_Components_Analysis> And, of course (sorry for insisting and self-advertising) my work (available at the link I've PMed to you). I've put a lot of effort to compile material & explain what PCA is, what it does and how it does it. It would be really nice, for me, to have some feedback if it helps, in any way, to understand PCA. If you had a look and found the material useless, please, be so kind and tell me so -- strait (PM or ML, the same). I'd really like to know what you think as I am planing to continue this effort in time, and expand it.

However, this is not really an alternative for creating random points within a irregular area. the v.random.cover addon script for grass 6 exists to do that. http://grasswiki.osgeo.org/wiki/AddOns/GRASS_6#v.random.cover '' v.random.cover is a shell script for creating random points constrained within an irregularly shaped vector area. (v.random places points only in current region rectangle). Optionally the user can upload raster values at the points. See also 'r.random cover= vector_output=' '' It's internal method is not especially efficient, but it gets the job done all the same.

My hope has been that with a bit of tweaking it would work. So I'm glad that you've had time to try it out. Thanks much. Michael ____________________ C.
