Re: [GRASS-user] error running digitzing tool wxpython
Hello Users-Group Doing some research the error below has something to do with the settings. I've set the snapping on 10 and save the settings. The tool runs more better but slower then v.digit (tcltk) the tool differs also from the v.digit tool Here is a link to three images. img1 ftp://80.61.251.86/grass64/J09v_digit.jpg img2 ftp://80.61.251.86/grass64/J09map_display.jpg img3 ftp://80.61.251.86/grass64/J09wxpython_tool.jpg A map with paved areas of roads: J09v_digit.jpg (v.digit map) every boundary is green with centriods in each paved area. J09map_display.jpg is th same map in the display this is correct. J09wxpyton_tool.jpg (same map wit the wxpython tool with the setting areas cheched 'on' This map is not correct. here is the link maps ftp://80.61.251.86/grass64/ What is wrong Joop Goedbloed Martin Landa schreef: Hi, 2008/11/21 Joop Goedbloed [EMAIL PROTECTED]: Grass6.4 is configured with --with-cxx --with-python --with-wxwidgets The wx digitizing tool runs fine zoomin and zoom out is running fine. as soom when I edit some vertex like movevertex splitvertex etc. the tool seems to hang and I become this errors. I will check it ASAP, I am out of the office right now. So, you open vector map for editing, choose vertex to be moved by left mouse button, error appears... Is it right?

[GRASS-user] r.texture NULL value error
Hi list, I've been trying to run a r.texture filter on a map but I constantly get the error: ERROR: Negative or no data pixel found. This module is not yet able to process no data holes in a map, please fill with r.fillnulls or other algorithms However, I ran r.null to set all NULL values to 0 and r.categories also showed no negative values afterwards. What could be the cause of this error. I also rescaled the categories between 0 and 100. After all this the ERROR is still their. Furthermore, If I run a 3x3 r.neighbourhood average moving window analysis on this map, r.texture runs fine on the result of r.neighbourhood. I really don't know what causes this inconsistent behaviour. Any ideas what causes this error? Kind regards, Koen ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

This module is not yet able to process no data holes in a map, please fill with r.fillnulls or other algorithms I ran into this myself a few minutes ago :) The trick is that *all* pixels in the current region are need to be set to non-NULL. If NULL pixels are present, r.texture fails. run r.univar mapname to see how many NULL cells are in the current region. Solution: - either zoom into area without NULL pixels (won't always make sense) - or fill the NULL areas with some value (various options) - (or fix r.texture if possible).
