California Landsat Images

This product was created by the U.S. Geological Survey (USGS) and contains Landsat data files in Geographic Tagged Image-File Format (GeoTIFF). The images have all been reprojected to the California Albers Projection, NAD 83 datum, and provided in GeoTiff format. Images from Landsat5 and Landsat7 available - see http://archive.casil.ucdavis.edu/casil/remote_sensing/landsat/

California DRGs from CASIL

The maps are organized into 1x1 degree blocks covering the state of California. The source maps for DRGs were georeferenced to the UTM grid, but DRG images for California are available in Albers equal area projection (see the projection information). A DRG is useful as a source or background layer in a GIS, as a means to perform quality assurance on other digital products, and as a source for the collection and revision of DLG data. Available as 7.5 minute, 30x60 minute, and 1x1 degree blocks - see http://archive.casil.ucdavis.edu/casil/maps/drg/ see also http://gis.ca.gov/DRG.epl

INTERIM 2005 National Agriculture Imagery Program (NAIP) County Compressed Mosaics

NAIP imagery is one-meter color Digital Orthophoto Quarter Quads (DOQQs) for the entire State of California. This is the first time that California has acquired one-meter natural DOQQs statewide in a single "season"/year. The Interim 2005 County compressed (15:1) mosaics are in MrSID format. See http://archive.casil.ucdavis.edu/casil/remote_sensing/naip_2005/

California Digital Ortho (Quarter) Quads DOQQs
