I'm trying to recreate the following Mean Precipitation Map on Spatial Analyst:
http://www.srh.noaa.gov/images/sju/climo/monthly_reports/ncdc_precip_normalsxm_PR_USVI_new.jpg

I have the point feature class with the precipitation values and the limit polyline.
What else do I need to do an Interpolation using the IDW method? Do I have to convert the points to polygons?
What values do you recommend to get a similar result?
Thanks a lot !!!!!!
