In our effort to further tap into the great potential of digital mapping tools and develop rich, seamless Geographic Information Systems (GIS) for our state, I am pleased to announce the release of a publically available statewide imagery data set for California. The National Agriculture Imagery Program (NAIP) has collected imagery for all of California this summer. The collection is finished and the compressed natural-color county data are now available for download at Those counties with large file sizes (4-gigabyte or larger) are not downloadable through the gateway, but will shortly be available through CalAltas ( The basic product for California was funded entirely by Federal sources this year, but it was very quick and generous Federal-state partnership of leveraged funds that enabled the immediate processing for the 4-band color infrared product. We will be receiving this 4th band in another 6-7 months. Thanks to the US Fish and Wildlife Service, the national Park Service, the US Bureau of Land Management, the Office of the State Chief Information Officer, the CA Department of Fish and Game, and the CA Department of Water Resources for the funding needed for the 4-band product. Having this single consistent imagery product available in the public domain is a great asset for California that will give GIS professionals better and more accurate information to serve the people of our state.
