[gradsusr] gradsusr Digest, Vol 39, Issue 87

Regarding display map outside shp file

I got the same problem ... but i have done it in a different way which
includes some manual work  . I have taken the lat,lon points of my region
and i created a matrix with ones at the required region with required
resolution  and remaining i made it zero using  grads and i made this into
grd file inorder to have equal size as that of our original data and
multiplied the data with data in grd .. so that it can display only regions
which u r interested .
