Hi List, I am experimenting with r.in/out.xyz. As far as I understand, r.out.xyz take a cell center coordinate and writes this and the associated z value into something(stout/file). Now I have recognised while importing the output with r.in.xyz that there is a different cell count with different rasters while the region is the same.
I have a region with 670480 cells (986 x 680). Each test raster (srtm data and derived slope from srtm) says the same with r.info. Now I get different messages from r.in.xyz for the cell count: The correct number of cells for the srtm data (670480 ) but another for the slope raster (667152). Checking the output files, the number of lines differ: 67048 lines for the srtm and 667152 lines for the slope raster. I am sorting the output by the z value in order to create classes of equal area and the import from the slope raster doesn't work as expected, there's a large amount of cells associated to the * - value (Null I presume) instead of the classes I defined. From the manual I read that NULL values are not exported by r.out.xyz. Is there maybe a problem with 0 (degree) values from slope?
