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).

Optech CZMIL Features & Benefits
yy Accurate land and water-depth measurements with short laser pulse widths, enabling true shallow-water bathymetry yy Circular scan pattern providing two ‘looks’ at any target, for optimal object detection yy System integration and communication via TCP/IP; web-based interface for real-time in-field r emote diagnostics
yy Simultaneous high-density topo/bathy data from a single laser, using a segmented detector capable of up to 70,000 measurements/second yy Three sensors integrated on-board: lidar, hyperspectral, and RGB camera
Applications yy Shoreline mapping and coastal management yy Harbor and navigation channel inspection yy Beach/coastal erosion monitoring yy Nautical charting
