Re: mask for Canada

Hi Debasish,

You might be able to accomplish what you want by using map fill resources mpFillAreaSpecifiers and mpMaskAreaSpecifiers to fill in all areas except Canada.

See example 4 at:

Or, if you have a shapefile that contains a full lat/lon outline for Canada, then you could use gc_inout to mask any data that's outside the area of interest. See examples 4 and 5 at:
