Hello Community, i have a question regarding grids in ARCMAP 10. So i have a layer of coordinates of climate stations over the outlines of river catchments. The goal eventually is to create a grid, with the stations being the center of each square. After that there should be calculated, how much share of the river catchment areas belongs to each station.

So my questions are:

1: How do I create a grid around the stations?

2: Which tool allows me to calculate the share of each station with the catchment areas?

In the picture above you can see the climate stations (blue dots) and the river catchment outlines, the important cathcments being brown.

Thanks for your help!

Georg
