Surdex provides services to federal agencies including the USDA National Agriculture Imagery Program (NAIP), numerous districts of the USACE, USGS, BLM, and NGA. They use our products for farm programs compliance, land cover analysis/update, erosion analysis, insect and infestation migration, flood control planning, levee construction, transportation and infrastructure planning, and other engineering purposes.Products typically include natural color and color infrared digital orthoimagery, LiDAR / elevation data collection, topographic mapping, planimetric feature extraction, and thermal mapping.

We also participate in special projects for defense mapping, Homeland Security, and other federal agencies including acquiring airborne imagery and LiDAR over areas of restricted and prohibited airspace such as the U.S. Capitol and the National Observatory.

5.3 Million Square Miles Over 12 Years

Surdex’s largest digital orthoimagery project is the USDA National Agriculture Imagery Program (NAIP). The program began in 2003 using film capture at 1-meter or 2-meter resolution over full or partial states, and by 2014 it had evolved to complete digital imagery acquisition at 1-meter or better resolution in 4-band format and under absolute accuracy standards and web hosting of preliminary and final orthoimagery.

Since the program began in 2003, Surdex has been responsible for over one-quarter of the orthoimagery:

  • Over 350,000 DOQQs
  • Over 5.3M square miles
  • 69 state projects
  • Net coverage of 30 states

Surdex opted to acquire all imagery with the ADS100 for the 2014 NAIP at an altitude sufficient to produce 1-foot (30cm) data for each of its states, covering over 435,000 square miles. The 30cm orthoimagery is available as licensed content through the Hexagon Valtus web services.
