With a wide range of digital sensors, Northrop Grumman can collect aerial imagery ─ high-quality ground resolutions of less than 5 centimeters (2 inches) flown from altitudes of 1,000 feet to 41,000 feet above ground level. Whether you need a single sensor or a multi-sensor coincident approach for your project, Northrop Grumman can meet your needs.
LiDAR Terrain Mapping
Northrop Grumman can provide accurate data while maintaining an aggressive time schedule. Our team of software developers continues to develop leading solutions to improve our deliverables.
Northrop Grumman has provided hydrographic surveying since 1980. We have extensive experience in both open-water and river environments. Our expertise ranges from traditional approaches to the deployment of side-scan and multi-beam sonar systems, velocity measurements, and acoustic doppler current profiles (ADCP). Our experience has taken us to every major inland waterway in the United States, the Intracoastal waterway, and coastal environments. We are adept in adapting to project specific challenges, and in applying the appropriate technology for a solution.
Land Based Surveying
We have licensed surveyors on staff in numerous states. In the 1980's, we adopted GPS technology and continued to expand our services with terrestrial LiDAR. Our survey crews are accomplished providers of geodetic, boundary, topographic, and location surveys. We also support all of our Digital Aerial Imagery projects with ground control surveys.
Northrop Grumman's variety of hydrographic surveying vessels ensures a platform perfect for any job in any environment. Our long history in GPS applications brings added expertise in acquiring highly accurate positional data during hydrographic surveys.
Northrop Grumman crews are well versed in library development and work with GIS services staff to insure proper collection of all utility features. We use the latest proven GPS equipment and develop custom-tailored solutions for our customers.
