[GRASS-user] image vectorization

[ambrish dhaka]

Hi All,
I have tried to process a LANDSAT TM image for finer identification of features. The area represent the lower Ferghana valley region. See image attached. The difficulty is how to proceed further.
I cannot create vector lines for the following reasons. r.thin does not produce neatly, vectorization produces intense line with poor feature demarcation. Can some efficient steps be suggested.
I shall be grateful.
Regards,
Ambrish
