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.
