Keystone Aerial Surveys, Inc. specializes in providing quality aerial surveys throughout North America, including Mexico and Canada. 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, 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.
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 has taken on many state-wide projects as well as township and county work. Over the last four decades Keystone has evolved and grown with the technology of the times without altering its long-standing commitment to acquiring quality aerial photography.
Keystone operates eighteen aircraft, thirteen metric film camera systems, four large format digital sensors and one LiDAR system; 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. Six of Keystone’s employees are ASPRS Certified Photogrammetrists. With this significant capability and over 49 years of aerial survey knowledge and the experience gained through managing and acquiring over 350 individual large-scale digital projects for various clients throughout the United States, Keystone is uniquely positioned to acquire aerial imagery collection projects with various requirements while ensuring the timely delivery of the best possible product.
The large complements of survey crews, aircraft, and the latest camera and GPS navigation equipment enables the maximum benefit from limited weather and sun angle. The IT Department designs and supports unique software and processes to expedite post processing while maintaining the quality expected from Keystone.
