[GRASSLIST:6875] Re: beginner's question

[Māris Nartišs]

Hi,

1. import ASCII data in to vector file (v.in.ascii);
2. create surface from imported data with v.surf.rst;
3. draw contours usin r.contour.

Most hardest part - how to find best RST tuning parameters. 

Bonus - You can visualize surface from 2. step with nviz :)

Read on manual and

wbr,
Maris.
