Hi everyone,

I'm trying to do a surface map like this one :

Of course, my domain is smaller :)

My entry are like that (polar stereographic grid from a numerical model):

lat    long    Data
40    -77.0    24.0        
42     -77.2    23.0
41    -76.0     22.5

So, i have about 58 pts on a 2° x 1° window in the North-Eastern US and the entry are unsorted and it's not a regular grid when I plot my points on a map.

I tried help.search("surface map"), but I found nothing.  It's probably in a package i still don't have.

Thanks for any help again!
