| Re: Zip Code centroids
Attached is a section of the map. (I am having trouble pasting it in the body of the reply) Notice that zip code 99017 straddles 3 of my territories: Orange, Yellow and Pink. However, because the centroid is located in Orange, it only shows up in the excel export in Orange, but not when I export data for Yellow or Pink. Could I convert the zip code boundary lines into shapes that I could name using the real zip codes and then query the two sets of territories? Or is there another solution? Any help is appreciated! Thanks, Judy |

Judy, I downloaded the shape-files of zipcodes from the USPS gazeteer and use them to queryshape. Not sure of the web address at the moment - matbe someone else knows. |

Zipcode (ZCTA) ESRI shape files from the 2000 census: Census 2000 5-Digit ZIP Code Tabulation Areas (ZCTAs) Cartographic Boundary Files - U.S. Census Bureau I wasn't able to find a newer public-domain set, but these are fairly accurate. You might try searching at USGS Earth Explorer or ESRI. HTH -Paul |
