PAS archived its one-millionth aerial photograph.

Pacific Aerial Surveys (PAS) has archived its one-millionth aerial photograph. Located near the Oakland Airport and owned by HJW GeoSpatial, Inc., (HJW) the PAS image library houses current imagery acquired by its flight operations and historic aerial photography of the San Francisco Bay Area dating from the 1920s. The display is open to the public. Since PAS acquires aerial photography of the entire Bay Area on a semi-annual basis, the library is a repository of vertical photos that record landscape changes over the past several decades. PAS uses proprietary software that makes it possible to search the archive geographically, facilitating searches for any site in any given year. In addition to the photography, satellite imagery from Landsat 7 and Space Imaging satellites are available at PAS.
