I am using ArcGIS 10.1 with Python 2.7 I have a point layer with thousands of points that each hold an id value of its owner. One owner can have multiple points, meaning that points can have the same owner_id. I want to create a raster that counts the number of unique owner_ids in each cell.
Is there a way to create a raster with a value containing the count of unique owner_ids? In other words, I want a raster with the number of unique owners instead of a raster with the number of points in each cell.
I have tried creating separate raster grids for each individual owner and its points (found it somewhere on another forum), but since my data in total is more than a million different owner_ids, this will take way too long.
