Barrier islands, headlands, and coastal shorelines provide numerous valuable ecosystem goods and services, including storm protection and erosion control for the mainland, habitat for fish and wildlife, salinity regulation in estuaries, carbon sequestration in marshes, and areas for recreation and tourism. These coastal features are dynamic environments because of their position at the land-sea interface.

Modeling Wildlife Habitat Using 3DEP Lidar

Continuous data on vegetation cover, height, and relative density are increasingly sought as useful metrics for determining animal habitat conditions across large areas. Airborne light detection and ranging (lidar) multi-return information provides a ready source of remotely sensed data that can directly estimate vegetation height and cover at appropriate spatial scales. The U.S.

Lidar and Multispectral Data for Assessing Texas and Oklahoma Songbird Habitat and Density

Submitted by atripp on Thu, 05/20/2021 - 15:22

National Wildlife Refuges (NWR) in Texas and Oklahoma manage forested habitats to support priority bird populations in the West Gulf Coastal Plain and Ouachitas Bird Conservation Regions. Airborne laser altimetry or light detection and ranging (lidar) can capture details of forest structure that determine bird species diversity, densities, and distributions.

Combining Elevation Data Sources and Statistical Simulation Improves Long-Term Mining Production Verification Analysis

The BLM’s National Operations Center (NOC) frequently assists field offices with production verification at mine sites across the West, but these analyses are often limited by a lack of historical data.

Unmanned Aircraft Systems-based Remote Sensing of River Discharge Using Bathymetric Lidar and Thermal Particle Image Velocimetry

Submitted by atripp on Mon, 04/06/2020 - 11:24

The USGS is developing innovative technologies and approaches for measuring river discharge using remotely sensed data. Given the expense associated with remote sensing from conventional aerial platforms (e.g., helicopter, airplane), unmanned aircraft systems (UAS) offer hydrographers a lower cost alternative for data acquisition.
