If you want an actual spatial dataset, the best place to ask is R-sig-geo
R has substantial capabilities for dealing with gridded spatial data,

Hi lily,
Something like this should work:
DF1<-read.table(text=
"latitude longitude Precip
45.5 110.5 3.2
45.5 1115.0
45.5 111.5 1.8
45.5 1122.0
46 110.5 6.1
46 1114.5
Hi R users,
I have a question about manipulating data. For example, I have DF1 as the
following, how to transform it to a gridded dataset DF2? In DF2, each value
Precip is an attribute of the corresponding grid cell. So DF2 is like a
spatial surface, and can be imported to ArcGIS. Thanks for your
