[GRASS-user] The upper limit for displaying large vector layers

Hi, the current GRASS versions share a constraint regarding the maximum size of _displayable_ vector layers. This affects both traditional GRASS monitors and map displays. While GRASS is capable to ingest and process rather large vector data sets, these can _not_ be properly be displayed when th

[GRASS-user] r.colors rules

ok guys, I have set a rule for r.colors such as: -4    0:0:0 -3    1:1:1 -2    2:2:2 -1    3:3:3  0    4:4:4 but how can I set the rule for values less than -4 and greater than 0?? thank you as usual, Alberto Pettazzi MeteoGalicia - Departamento de Climatología y Observación

Re: [GRASS-user] r.colors rules

What I would like to do is something like this: <-4 255:255:255 -40:0:0 -31:1:1 -22:2:2 -13:3:3 04:4:4 >0255:255:255 I tried to do this way, but it doesn't seem to be the right way thank you again Alberto Pettazzi MeteoGalicia - Departamento de Cli

[GRASS-user] output r.out.ascii

Hi list, I'm trying to use r.out.ascii to dump a map (or better a masked part of it) to stdout. I would then use sed to clean up the data so I'm only left with the pixel values and no spatial information (don't need it). However, If I run something in the lines of: r.out.ascii -h input=patch

[GRASS-user] Overlapping polygons and v.distance

Greetings all, Summary: I would like to request that the v.distance function be updated (with a flag?) to allow reporting of multiple categories in one layer. Example of why this can be important: I am working with historical forest fire data and want to extract histories for different points.
