I need some assistance with GIS and was wondering if anybody can help me. Essentially, I am looking to connect census tracts and zip codes (ZIP Code Tabulation Areas) in the following way (nationwide):
- Take the centroid of a census tract and connect a zip code to that tract if the centroid of that zip code is within 5 miles of the census tract's centroid.
I will be using ArcMap 10. I'm new to GIS so if anybody could explain to me step by step on how I can do this then that would great. Hope you guys can help. Thank You!
