I have two layers: one point and one polygon grid layer. Trying to count the number of points in each grid polygon and have it become an attribute in the polygon layer. Currently using ArcGIS 10 with HawthsTools>Analysis tools>Count points in polygon to accomplish this task manually, but I want to bake it into a model. I can't figure out how to add HawthsTools into model builder. Why is this? I have not yet installed Geospatial Modeling Environment, which is the new iteration of HawthsTools. Does GME play nice with model builder? If not, what solutions can you suggest?
The closest I've gotten is finding a python script that will count points in polygons. http://forums.arcgis.com/threads/23838-Using-Point-in-Polygon-in-Modelbuilder. Can I use this in a model? Hand holding on how to accomplish this would be very, very appreciated.
