City and County of Broomfield Awards LIDAR and Digital Ortho Contract to Spectrum Mapping

Denver, Colo. – December 13, 2005 – Spectrum Mapping, LLC announced it has been awarded a contract by the City and County of Broomfield, Colorado to collect aerial LIDAR and digital ortho imagery of approximately 40 square miles and provide derived value-added information such as contours and feature extraction.

Spectrum Mapping will provide the City and County of Broomfield six-inch pixel, orthorectified color digital imagery, Digital Elevation Models filtered to a bare earth surface to create Digital Terrain Models capable of supporting 2-foot contours and 2-D building footprints.

Adrian Kropp, GIS specialist with the City and County of Broomfield and project manager for acquisition of LIDAR and aerial imagery said, “With updated imagery, building footprints, and a DTM, we can better support all other departments with more accurate maps. Additionally, Broomfield Emergency Management planners will benefit from access to 2-D building footprints and the highly accurate DTM.”

“The City and County of Broomfield had stipulated in their Request for Proposals that the LIDAR and aerial imagery be acquired simultaneously because of the numerous benefits and cost savings that can be derived from this method of data acquisition, said Barry Perow, vice president of Spectrum Mapping, LLC. “By using an integrated digital camera with the laser system, Spectrum Mapping is able to collect stereo imagery concurrently with the LIDAR data, eliminating the need for multiple flights and aerotriangulation, and facilitating the editing and quality control process. It is has long been our contention that LIDAR DTM data cannot be “blindly” filtered. The digital imagery is vital to the filtering of the LIDAR points and is used to quality control the bare earth DTM surfaces.”

Many of the processes called for in the City and County of Broomfield’s RFP were developed by Spectrum as a result of two major contracts from the U.S. Army Corps of Engineers Small Business Innovative Research (SBIR) program to evaluate automatic feature extraction, classification, LIDAR filtering techniques, and the capability to digitally extract 3-D earth surface feature information from LIDAR data. Spectrum also developed the LAS format for LIDAR data that has become the industry standard and adopted by the major photogrammetric software and LIDAR system providers, US Army Corps of Engineers and The American Society for Photogrammetrists and Remote Sensing (ASPRS).
