Our History

Celebrating over 100 years of innovation

102-Year Track Record

Intermap has a long history of collecting, processing, analyzing and delivering 3D terrain data, from all sources, to solve problems with speed, accuracy, recency and global scale. We are celebrating 102 years of history in June 2021.

Intermap’s history begins in 1919 when its predecessor, Pennsylvania Aero Service Corporation, was founded as North America's first aerial survey company. In 1920, it changed its name to Aero Service Corporation.

Timeline: Evolution of Intermap

1919

Intermap’s founding company, Pennsylvania Aero Service Corporation, became the first aerial survey company in North America. Aero collected the first aerial imagery of Pennsylvania by mounting a camera on an aircraft.

Aero Service Corporation is the oldest flying corporation in the world. Aero used aircrafts to collect aerial photos of Philadelphia using a 20-inch focal length glass plate camera attached to the plane’s cockpit cowling.

In 1928, Aero completed an aerial survey in Philadelphia covering 4,000 square miles.

In 1932, Aero collected aerial imagery for the entire state of New Jersey, marking the first time a complete state was photographed.

1934

In 1934, the Tennessee Valley Authority required development of the potential resources of the 43,000 square miles of the Tennessee River Watershed. Topographic map coverage at scales of 1:62,500 and 1:125,000 was sparse. Aero Service was awarded a contract to produce the aerial photography and compile mosaics. Aero assigned two "Fairchild 71" aircraft, each equipped with a camera. All flight layout, film processing, printing, mosaicking, copying and reproduction were completed by Aero. The camera used resulted in a central vertical and four oblique negatives simultaneously. The side oblique views (43⁰ from the vertical) were transformed in a special printer to near-verticals. Each mosaic board covered 7.5 minutes of longitude and 15 minutes of latitude, at a scale of 1:20,000.

1938

In 1938, Aero compiled precise photo-mosaics of 11,000 square miles of Utah for the Soil Conservation Service. Aero photographed the project areas and rectified the photos to fit the specifications. The rectification was accomplished with a precision rectifying camera designed and built by Aero.

Aero participated in several important projects, including work with the U.S. Geological Survey and for the European and Pacific theaters during World War II.

1983

Intera won a three-year contract with Canadian Marine Drilling Ltd. (CANMAR), a subsidiary of Dome Petroleum, to monitor shipping lanes in the Beaufort Sea. Intera developed surveillance devices billed as the most advanced commercial ice early warning system in the world. The STAR-1 system (Sea Ice and Terrain Assessment Radar) allowed drill ships to identify ice floes as small as 15 - 20 meters in size previously overlooked by other devices. Under the contract, Intera set up the STAR-1 surveillance flights from Inuvik, N.W.T. on a daily basis during drilling at a well named Kogyuk N-67.

1992

1992

From 1992 to 1996, Intera was involved in the Central African Parks project creating topographic maps for all of Africa’s tropical forest parks. Around the same time, Intera also operated STAR-2 for ice reconnaissance to support arctic shipping lanes and operated STAR-1 for terrain mapping around the world.

1996

Intera split into three groups: Intera Environmental, Schlumberger (acquired the petroleum portion), and Intermap (remote sensing group). Intermap acquired the world’s most advanced terrain data collection system from DARPA.

Mapping with a B-17 Flying Fortress

Aero Service Corporation operated N5017N, a Boeing B-17 bomber, from 1949 until 1962. During the 13 years, the aircraft flew almost one million miles, which is enough to circle the globe more than 35 times. Prior to Aero’s purchase of N5017N, the aircraft was used to ferry fresh shrimp to east coast markets as it was manufactured too late to participate in WWII.

N5017N was flown all over the world, flying at 30,000 feet, to collect aerial imagery for various mapping projects. During September and October of 1956, the aircraft flew 44 consecutive days to obtain photo coverage of 150,000 square miles of Saudi Arabia.

In the summer of 1962, the aircraft was sold to Chris D. Stoltzfus & Associates, of Coatesville, PA, to be used for forestry dusting operations and fighting forest fires. On March 31, 1981, N5017N was donated to EAA restoration program to maintain the aircraft in airworthy condition.
