Hi,
I have a series of drive time radii, in minute-long increments expanding out from a single origin. I'd like to summarize the geographical proportion of each ZIP code that falls within each radius - i.e., how much of each ZIP is within 1 minute drive of the start point, how much within 2 minutes etc.
I have been able to do this by performing individual analyses for each radius and exporting the results, but it is very labor intensive. Is there a way to use a single drive-time area with multiple radii, and to use the 'summarize within' tool to output all variations in a single file?
Many thanks
Dan
