dear grass user,

I am new in grass using windows native GRASS GIS 6.3.0.4 and i am having problem to digitize a map. I will be very gratefull if you could help us.

Problem

A model map is as example for my problem.

Ø My first step I have digitized the polygon dhk (showed in attached picture).

Ø Now I have split two points and add node. Then I have drawn polygon of khl.

Ø Then I have added centroid . It is not regioning with the polygon.

Ø I have tried same problem with QGIS with grass extention. There after digitizing a simple polygon as shown picture e.g dhk .

Is my procedure is correct ?

I am little confused with the digitizing tool though I have read the manuals.

Best

I’m not quite clear what your problem is. What do you mean “not regioning with the polygon” ?

But perhaps this might help:
