Currently I have:
A polygon layer with a population attribute
A point file containing facility locations.
Facility A has a catchment area of x amount of people. What tools can I utilize that will allow me to create a catchment of those polygons that bring a sum of x?
Is there a tool in Arc for this? Is there a tool elsewhere? ie; FME?
Thanks very much,
That would work... an attribute selection, then successive select by spatial location. The the obvious limitation is that the progression outward would be much like a buffer, which may not represent the actual population pattern about the facility.
