<div dir="ltr"><div>Hi all,</div><div><br></div><div>First of all, I must say sorry for my immature question. As I stated before I am a novice user. It took me a lot of time to find that elevation files can be directed from the internet. Silly me thought I can create those files from GRASS GIS itself. Anyways I thank everyone, who spend their time in solving my problem.

I will add that we need a definition of 'location.' Do you mean one point<br>
or a defined area such as a drainage basin?<br>
