Keystone Aerial Surveys, Inc. specializes in providing quality aerial surveys throughout the United States. Keystone has flown millions of survey miles throughout the United States on projects with various specifications. We have four locations; Philadelphia, PA (headquarters), Tyler, TX, Benson, AZ and Los Angeles, CA. The Flight Department has considerable experience collecting airborne imagery at high and low altitudes in several formats including film (color positive, color negative, color infrared, black and white, black and white infrared) and digital (RGB, NIR, 4-band) and LiDAR. Keystone also collects and provides both Airborne GPS (ABGPS) and Inertial Measurement Unit (IMU) data.

Our 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.

Keystone operates aircraft, film camera systems, large format digital sensors and 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. Many of Keystone’s employees are ASPRS Certified Photogrammetrists.
