California aerial photo dataset

Aerial Services unveiled this week a collection of over 20,000 high-resolution aerial images encompassing more than 3,500 square miles of California, including both urban and wetland areas. The collection is available on a per-image basis for business and government users.

All images are less than one year old. These vertical aerials, acquired using state-of-the-art Canon digital imaging systems, are geo-referenced and may be interfaced with any number of mapping and photo systems. Images can also be geo-rectified for use with ArcGIS, AutoCAD, MapInfo, Google Earth, and MicroStation systems.

The availability of the digital library is the result of a three year development effort for aircraft camera equipment as well as flight planning and management systems. All 2008 dated photos have a nominal resolution of eight inches or less per pixel. Aerial Services also offers a 2007 photo inventory covering similar areas, which boasts a still-impressive 12 inch pixel resolution.

“We believe that we have the highest-resolution and most recent aerials on the market. We expect to have new images for any given area two or three times a year,” said Andrew Leonard, operations manager for Aerial Services.

Coverage maps are available on the Aerial Services website at An easy-to-use Google EarthTM coverage database is available for seven core California regions.

Custom aerial imagery and mapping is also available. Based on customer specifications, Aerial Services can provide high definition survey services for up to 350 square miles per day. For special projects, Aerial Services can also offer extraordinary images up to 1 inch pixels. Survey specifications can be sent to Aerial Services in the form of ArcGISTM shape files or Google EarthTM KML files. Geo-located image data is generally available overnight or within 24 hours of a flight, and custom map data within 3 business days.
