When nightly migration starts or ends, birds transition vertically through the airspace where there is the potential for collision with anthropogenic structures.

Carbonate precipitation can occur where groundwater enters lakes and supplies chemicals missing from the lake, creating carbonate mounds called tufa mounds or microbialites. These precipitates can often be associated with microbes that either create micro-environments that encourage precipitation or act as templates for precipitation.

To validate the quality of light detection and ranging (lidar) data collected for the 3D Elevation Program (3DEP), the USGS uses methods detailed in “Accuracy Standards for Digital Geospatial Data” developed by the American Society for Photogrammetry and Remote Sensing (ASPRS).

Low-lying island environments, such as the Majuro Atoll in the Republic of the Marshall Islands, are particularly vulnerable to coastal flooding (inundation) whether the increased water levels are from episodic events (storm surge, wave run-up, king tides) or from chronic conditions (long-term sea-level rise). Land elevation is the primary environmental variable that determines exposure to inundation in coastal settings.

During 2019, the Avian Radar Project surveyed the migration of birds and bats in the Detroit, Michigan, area using mobile avian radar units.

BOR is a key partner in the Trinity River Restoration Program (TRRP), located in far northern California. Remote sensing for the TRRP includes annual high-resolution aerial photography (0.5-foot pixel resolution), which provides a standard point of view for detecting morphological and vegetation changes to the river channel and floodplain.

The USGS National Land Imaging Program (NLIP) has built a long-term capacity to collect and analyze land imaging user requirements to advance the Nation’s operational and science objectives and better serve the land imaging community. The USGS documents the land imaging requirements of U.S.

In late May, the Department of the Interior (DOI) announced that the LANDFIRE (Landscape Fire and Resource Management Planning Tools) Program was the recipient of the 2017 DOI "Environmental Dream Team" award.  The award recognizes the program team as exceptional environmental champions and agents of change. Led by the DOI and the U.S.

The Landscape Fire and Resource Management Planning Tools (LANDFIRE) Program developed the original LANDFIRE National product suite using Landsat data (circa 2001) to identify disturbances on the landscape. Although these products were updated regularly (LF 2008, 2010, 2012, and 2014), the base layers themselves are now more than 15 years old. To make the base data current, LANDFIRE is remapping the United States to produce a new product suite.

High-resolution digital elevation models generated from airborne lidar are often used for studying dynamics specific to barrier islands, including assessing morphology, extracting shorelines, and mapping habitats. While airborne lidar data have revolutionized the spatial scale for which elevations can be realized, elevation uncertainty limitations are often magnified in digital elevation models in coastal settings. For instance, researchers have found digital elevation models produced from airborne lidar can have a vertical uncertainty as high as 60 centimeters in densely vegetated marsh.
