St. Petersburg Coastal and Marine Science Center
The Lidar for Science and Resource Management (LSRM) project, sponsored by the USGS Coastal and Marine Geology Program (CMGP) is supporting the creation of new capabilities for the synoptic remote sensing of coastal-marine and terrestrial environments based on aircraft and satellite sensors. These coastal remote-sensing, mapping, and point-monitoring tools constitute a unique integrated package of instrumentation and software that may be deployed in support of appropriately timed and scaled zoning decisions by management authorities in order to conserve and sensibly exploit nearshore coastal and marine ecosystems.

Lidar Topographic and Bathymetric Mapping in NPS Parks
Lidar data acquired by the USGS in collaboration with the U.S. National Park Service are being used to inventory and monitor marine benthic communities, barrier island geomorphology and vegetated habitats along coastlines for National Parks.
Barrier Island Volumetric Change Analysis
Lidar-based volumetric change analysis along barrier islands provides a valuable tool in quantifying morphologic change following major storm events.
Lidar-Based Vegetation Metrics
As a full-waveform digitizing lidar, the small-footprint EAARL waveforms can be used to generate accurate estimates of vertical canopy structure in coastal vegetation communities.
Lidar-Based Vegetation Delineation
Lidar-based vegetation metrics at 5-m-resolution of bare-Earth (BE), canopy heights (CH), canopy-reflection ratio (CRR), and height of median energy (HOME) were used as input to a model-based approach to delineate coastal vegetation communities.
Coral Reef Applications of Airborne Lidar and Digital Camera Surveys
Special emphasis has been placed on the use of aircraft lidar and multi-spectral imaging to map coral reef ecosystem geomorphology, topographic roughness, and habitats at spatial scales finer than 2 meters.
GIS Application Example—NPS Inventory and Monitoring
Lidar is used by the National Park Service to track changes in terrain along coastal barrier island beaches for inventory and monitoring of terrestrial and aquatic environments, assisting in comprehensive natural resource management.
From March 3–6, Dave Zawada, Rudy Troche, Dave Nagle, Xan Fredericks, and Christine Kranenburg are meeting with U.S. Army Corp of Engineers and National Oceanic and Atmospheric Administration colleagues at Stennis Space Center to discuss protocols and methods for processing raw lidar data. The goal is to share respective experiences of the groups, and to identify ways to streamline and improve procedures for transforming raw lidar data into useful data products.
