I have thousands of points across Canada, as well as thousands of polygons. Each polygon represents a population (approximately 550 people). The points are across a rail network. What I need to do is find out the population within a half mile radius of each of these points.
For each Polygon I know the population density, and I've created a 0.5 mile buffer around each of the points, but I can't calculate the number of people in each 0.5 mile radius because many of the buffers contain many polygons, each with a different population density and with different amount of coverage of each polygon.
Any help would be very appreciated!
