This page describes the data layers in our GIS library. This descriptive information is metadata. Applications such as PimaMaps and the Pima County Geospatial Data Portal include many of these layers. Conversely, many library layers are not included in those products. In addition to searching and displaying metadata here, you can retrieve the Metadata Database in Comma-delimited Format.
For more about our metadata, see and Metadata Field Descriptions (what's in the metadata).
