PE&RS April 2008

This month’s cover, provided by Pinnacle Mapping Technologies (www.pinnaclemapping.com), shows direct-digital aerial imagery acquired by the state-of-the-art DiMAC 2.0 (Digital Modular Aerial Camera) digital camera sensor. The images show a portion of a roadway project fl own at Riviera Beach, Florida in the spring of 2007. The 3-inch (0.25’) pixel color orthophotos, fl own at 2894’ AGL, were used to detect changes along the roadway corridor from previous survey and photogrammetric mapping projects. Once the areas of change were located with the new orthophotography, stereo-compilation was performed to update the Digital Terrain Model and transportation-related planimetric features along the corridor at a map scale of 1”=40’.

Pinnacle utilizes Intergraph photogrammetric software to perform aerial triangulation, stereo-compilation, orthorectifying and mosaicing of the aerial imagery data. The images of Rivera Beach are particularly exciting because 2007 was the fi rst year that the DiMAC 2.0 was in operation in North America as a large format digital aerial sensor. In 2007, Pinnacle acquired over 100,000 images with the DiMAC in the United States and Canada for a variety of clients and end uses.
