Hello,
I found the python matplotlib basemap toolkit as an easy and fast tool
to plot data from a xyz data file (regular spaced) as a contour map.
For an online example see:
http://matplotlib.sourceforge.net/screenshots.html
What is the GRASS workflow to accomplish this?
I dis:
v.in.ascii my_xyz
v.surf.idw
But the result map was rather coarse with a lot of pixels and no
definitive contours. The same data contoured with matplotlib lead to a
nice plot.
Thanks in advance,
Timmie
