Keystone Aerial Surveys, Inc specializes in providing quality aerial surveys. Keystone has flown millions of survey miles throughout the United States on projects with varied specifications. We have four locations; Philadelphia, PA (headquarters), Tyler, TX, Reno, NV and Los Angeles, CA. The Flight Department has considerable experience collecting airborne imagery at high and low altitudes in several formats including digital, film and LiDAR. Keystone also collects and processes both Airborne GPS (ABGPS) and Inertial Measurement Unit (IMU) data.
Its history of success uniquely qualifies Keystone to fly large statewide, and multiple county projects in one season. Keystone is expert in the execution of projects in all types of terrain and weather conditions as well as in restricted airspace. Keystone has extensive experience in contract management of large, complicated projects where quality control and communication are paramount. On the Federal level, Keystone has worked for the USDA (NRI, WRP and NAIP, Forests), USGS, BLM, FEMA, Corp of Engineers and NOAA.
Keystone operates one of the largest private fleets of aircraft, metric film camera systems, a suite of large format digital sensors and multiple Optech LiDAR systems; employs flight crews consisting of pilots, camera operators, four full time licensed aircraft mechanics and a fully equipped and staffed photo lab and IT Department for extensive post processing support. Two of Keystone’s employees are ASPRS Certified Photogrammetrists.
