,This is a point layer of Military Airports currently permitted by the State of California, Department of Transportation (Caltrans), Division of Aeronautics. The attributes include the airport location, function class, ownership, and the link of Federal Aviation Administration (FAA) site. FAA website has airport detail information and master records and reports.,

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.

,The purpose of the data is to represent the rail network using available reference data and information contained in the California Region Timetable 20. The Rail feature class contains alignment for passenger and freight railroad lines, including commuter rail and heavy rail. The Rail feature class allows for the selection of all passenger, commuter, recreational, freight, and shortline rail alignment in California with the exception of BART.,

Simple polygons of airport data, specifically aircraft movement areas and airport boundaries. Data created with ArcGIS software and is in ESRI shapefile format.

The location of infrastructure associated with aviation facilities such as helipads, helispots, helibases, airstrips, landing grounds and associated infrastructure such as ground to air markers and windsocks as depicted in the PWS Asset Management System (AMS). The majority of included features are owned and/or managed by PWS, although some that are of strategic interest to PWS are also included. Infrastructure is on reserved and crown land.
