Shown below is the Google Earth view of a 150 square mile survey which we conducted on June 18, 2008 over Sacramento, CA. The flight lines were approximately 15 miles in length and 3,170 feet apart. These tracks are nominally accurate to within 20 feet of our GPS plans thanks to our staff of seasoned former airline pilots. Such accuracy coupled with the quality of our camera systems ensures that side-to-side overlap on images is sufficient enough to mosaic images if requested by the customer. Our stringent flight path standards ensure that Air Traffic Control understands our intentions even in the busiest of urban airspace like that of San Francisco and Los Angeles.
