filter out points in file over ocean/land

[Greg West]

All,

I have a text file with a list of coordinates of points (x,y and lat
lon) over North America and the surrounding oceans. Is there a way to
divide them up (maybe using masks somehow) into ones that are over the
oceans and ones that are over land?

Thanks for your help,
Greg
