I'm trying to create a map that identifies service areas based on population surrounding a feature. In this case, the features are neighborhood parks, and service areas are determined by the capacity each park has to serve the neighborhood. For example, a small park with some open space and a basketball court serves X people - I want to use population point data to output a shape encompassing the nearest X people to a given park feature.
I have data for the service capacity of each park in the study area, and I have population point data. How can I generate shapes that encompass a set value of points around each park feature?
