Hi,

I have a mesh of 1 sq.km polygon data (created using the fishnet tool in ArcGIS) and I have four points within each of those square grids. I want to calculate the sum of the values of a particular field associated with those points. So, I am looking for one value within a 1sq.km polygon that is derived by adding the values of a particular field of those four points. Is there any tool in ArcGIS or any script that can help me to achieve this? Any kind of advise will be greatly appreciated.

Thanks very much,

Tilottama
