[GRASS-user] Exporting raster maps into structured ascii file (X, Y, value, ...., value)

[Daniel Victoria]

Hi,

Take a look at the r.what man page...
http://grass.osgeo.org/gdp/html_grass63/r.what.html

I did something similar but for a few points. What you will have to do
is create a list with the x,y coordinates that you want and then pass
it to r.what

You could create your x,y list by hand or, using r.to.vect and convert
one of your rasters to points...

Cheers
Daniel
