[GRASS-user] Help needed for ascii point export

[jctorres]

Hello

You can create a map of these points contining the elevation as 
attribute. Once you output this map you could sort points using the 
elevation values.

you can do this for instance using v.to.rast to convert the points to 
raster, them combine this map with elevation using r.mapcalc (assigning 
elevation to the points), and them output the map using r.out.xyz.
To sort the points you can use any sort program or a spreadsheet.


Best regards
