querry for color

[Dr. A. K. Sahai]

Dear Grads Users,
                Suppose I have masked ocean (in blue color) and land (in
green color) with basemap.gs.
Now I want to know what is the color filled at a particular point. Since
I have to determine it for sevaral
thousand points, it has to be done automatically in a grads script. How
can I do it. For example I have
a point with latitude 20.625 and longitude 110.75. Then I have to do
'set lat 20.625'
'set lon 110.75'
then what querry should I ask to now the filled color at that point.

Hope someone will give some clue.

Regards
Sahai
