Automated Detection of Wildlife Targets in Aerial Imagery

Submitted by atripp on Thu, 06/17/2021 - 15:16

The USGS is advancing the development of machine learning algorithms to detect and classify seabirds, waterfowl, and other marine wildlife from digital aerial imagery in collaboration with Bureau of Ocean Energy Management, U.S. Fish and Wildlife Service, and the Vision Group at the International Computer Science Institute.

21st Century Surface Water Trends for the United States

Submitted by atripp on Tue, 06/15/2021 - 15:42

The USGS Patterns in the Landscape–Analyses of Cause and Effect (PLACE) project has developed a new suite of surface water maps derived from Moderate Resolution Imaging Spectroradiometer (MODIS) imagery.  These maps leverage the MODIS daily acquisition rate and the Dynamic Surface Water Extent (DSWE) algorithm to create a record of surface water change with reduced cloud obstruction compared to Landsat-based maps.

Using Imagery to Crowdsource The National Map

Submitted by atripp on Tue, 06/15/2021 - 14:42

The National Map Corps (TNMCorps), a crowdsourced mapping project, relies on volunteers to assist the USGS National Geospatial Program by collecting and editing man-made structures data for The National Map. Through their participation, volunteers make important contributions to the USGS’s ability to provide the Nation with accurate mapping information.

Innovative Technologies to Monitor a New Crater Lake at Kīlauea Volcano

Submitted by atripp on Thu, 06/03/2021 - 15:18

From May to September 2018, Kīlauea volcano experienced its largest eruption in more than 200 years. The eruption drained the summit lava lake and shallow magma reservoir, covering the volcano’s lower East Rift Zone in 35 square-kilometer of lava. Successive collapse events at the summit resulted in a collapsed crater more than 500-meter deep.

Mapping Habitats in Beach, Dune, and Intertidal Environments

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.

Structure from Motion Modeling Using Unmanned Aircraft Systems to Support Paleontological Surveys

Submitted by atripp on Tue, 06/01/2021 - 14:15

The USGS National Unmanned Systems Project Office (NUPO), in collaboration with the Denver Museum of Nature & Science, constructed a photogrammetric three-dimentional digital surface model (DSM) and orthometric image map via an unmanned aircraft system (UAS) using Structure from Motion (SfM) techniques.

Monastery Run Wetland 1 near Latrobe, Pennsylvania, is a passive mine water treatment system constructed in 1997–1998 to treat multiple discharges from an abandoned underground mine. The OSMRE Technical Support Division assisted the Pennsylvania Department of Environmental Protection (PA DEP) with diagnosing issues and improving the effectiveness of the water treatment system.
