Dear Armel,

Hi,

I'll try it out. I thought it "does just surface".

Thanks!

Hi,

Try SAGA GIS software.

Bartlomiej,

Thanks.

I have not seen ready solutions for this basic task yet, but maybe Saga is easy enough for me.

Hi there, QGIS is a great open source GIS software. Being a full GIS software it will take some learning on how to use, but should be easy once you know how.

Richard,

Thanks!

So I would have much to learn, but what not to do to get knowledge about morphology. I will continue (some day). I thought it would be easy to select a part of the model (grid) and see the features, but at first glance. Many programs don't seem to accept a part of the model as an object or a choice for information. I guess I must extract or define first landforms by program operations to get information about those pieces of the model, but it requires some GIS skills. Landserf, Microdem or Whitebox, complemented by InterImage, may be nice, but so far I haven't done any of these with them, and I wonder if it's even possible (for me).

Ayan,

Thanks!

I still have a lot to learn on this topic.

I have not yet gone very far on this issue.
