- Abstract: This dataset contains the estimated geographic extents for all five digit zip codes in Utah that are not P.O. box only.
Boundaries.ZipCodes represents an ongoing effort to approximate the geographic extents of five digit zip codes. The dataset was produced using a combination of methods and is based on several sets of source data. Editing methods include:
- Using local zipcode polygon data obtained from counties and cities.
- Identifying place locations (cities, towns, populated areas, etc.) from the postal service website and address information system (AIS) and building zipcode boundaries around these places.
- Using the 2000 Census TIGER line file’s zip code attributes.
In addition, AGRC has used the locations of mailing addresses known to be valid to fine tune this dataset. The native spatial reference for this dataset is UTM Zone 12N, NAD83 (0.01 meter coordinate precision). There are no constraints or warranties with regard to the use of this dataset. Users are encouraged to attribute content to: State of Utah, SGID.
