Time series interpolation in ArcGIS

Discussion created by madtraveller on Nov 20, 2010
Dear all,

I'm trying to calculate average rainfall value from a number of points using Inverse Distance Weighted tool in ArcGIS 9.3. My problem is that: each point has it own time series, therefore the interpolation process should be able to carry out for year after year. Following is a sample attribute table:

ID X Y Name Rain1990 Rain1991 Rain1992 Rain1993 .... Rain2010

1 xx1 yy1 AA 1210 1189 1863 1269 ...... ......
2 xx2 yy2 BB 1492 1502 2187 1923 ...... ......

Could anybody show me how to do that. Any suggestion would be much appreciated

Nice weekend every1
