Optech CZMIL
Optech CZMIL is an innovative airborne coastal zone mapping system that produces
simultaneous high-resolution 3D data and imagery of the beach and shallow water
seafloor, including coastal topography, benthic classification and water column
characterization. CZMIL performs particularly well in shallow, turbid waters. Its
bathymetric lidar is integrated with a hyperspectral imaging system and digital metric
camera. Optech HydroFusion, a powerful end-to-end software suite, handles all three
sensors—from mission planning through to fused lidar and imagery data sets.
Optech CZMIL was designed by Optech for the U.S. Government under the auspices of the U.S.
Army Corps of Engineers (USACE) and the Joint Airborne Lidar Bathymetry Technical Center of
Expertise (JALBTCX). It was built and tested by Optech with the assistance of the University of
Southern Mississippi (USM).
