California department of transportation (Caltrans), Division of Aeronautics provided airport layout drawings with estimated digitized airport property or fence lines with Google Pro images background.
Caltrans Division of Research, Innovation and System Information (DRISI) GIS office digitized the airport boundary lines with Bing Maps Aerial background and built the boundary lines into a GIS polygon feature class.
Generally, Airport Layout Plans do not show complete connected property or fence lines. In many cases the boundary lines were interpreted among the property and fence lines with our best judgement. The airport general information derived from FAA Aiport Master Record and Reports with their URL are included in the attribute table.
Airport boundary data is intended for general reference and does not represent official airport property boundary determinations.
