Spectrum Mapping, LLC was tasked by MAPVI - URS Corporation, Albuquergue, to provide
airborne Light Detection and Ranging (Lidar) of approximately 620 square miles around
Nueces County, Texas. MAPVI (Mapping Alliance Partnership VI for FEMA Region IV) is
a joint venture of URS Corporation, Greenhorne & O'Mara and Spectrum Mapping. Spectrum
followed data collection and processing procedures for Federal Emergency Management
Agency (FEMA) Guidelines and Specifications Appendix A. Data product deliverables
included Lidar to support 2 foot contours. Spectrum's acquisition division collected
the Lidar data on June 19, 22-25, 27, 28 and July 16 and 17, 2006. The project was
collected with a Rams ALS50 Lidar sensor, including an inertial measurement unit (IMU)
and a dual frequency Global Positioning System (GPS) receiver and antenna. Upon receipt
of this data, the NOAA Coastal Serices Center reclassified all non-ground data to
a classification of 1 (Unclassified) and all ground points to a classification of
2 (Ground).
