I, as a new comer to GrassGIS, trying to learn by reading online
instruction and using related dataset. But I find those tutorial are
written for Older Version and thing are not working as such. So, If I
am able to go through with the help of list members, then I will
rewrite or post comments, so that newcomer may take a smoother ride.
So, I request knowledgeable list member to solve following problem.
Thnaks in advance.
