Mask Ocean

[ousmane]

Hi bamba,
here is an answer of this question posted sometimes:
====
yes you can do so using basemap.
You'll have, first, to display a parameter and then you call the basemap.gs

Usage:
basemap L(and)/O(cean) <fill_color> <outline_color>
<L(owres)/M(res)/H(ires)>'
Example:
ga-> set mpdset mres
ga-> display PRMSLmsl
ga-> basemap L 7 2 M

will only display the land in medium resolution with color 7 and outline
in color 2 (red I think) M for medium resolution which corresponds to
the set mpdset.
Be carrefull because it could take a long time if you use the hires.

hope, it will help you.
