Digital Orthophotography Project
Summer/Fall 2006

The Client: Municipality of Anchorage, Alaska

The Project: Digital color orthophotography to be used for future planning by more than ten municipal departments in the greater Anchorage area.

Our Work: Kappa was responsible for flight planning, aerotriangulation, DTM integration, orthorectification & mosaicking, color balancing, image tile layout and delivery.

More specifically, we

  • Provided digital color orthophotography of Anchorage, Alaska, obtaining color high-altitude (18,000í above ground) imagery of the entire 1 million-acre municipality at one time Ė a cost-effective approach, but also a challenge because of the variation in elevations, which ranged from sea level (0í) to the mountains (6,000í) that surround the Anchorage Bowl.
  • Carefully processed the images to minimize tonal differences resulting from the large geographic area covered and delivered a final product that met the specifications of many different Municipality of Anchorage (MOA) departments: Project Management & Engineering, Emergency Management, Police, Fire, Health and Human Services, Heritage Land Bureau, Traffic and Public Transports, Parks & Recreation, Economic & Community Development, E911, Public Works, Water and Wastewater Utility.
  • Successfully merged various qualities of digital terrain data: LiDAR data covered specific areas, and USGS DEMís filled in the rest. A DTM was necessary for orthorectifying images and correcting for relief displacement, significant issues in this project.
  • Provided MOA with images (including metadata) in compressed image format and tiled to an existing municipality grid.

Partners: We teamed with The Boutet Company, the prime contractor.
