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

The USGS is coordinating a 3D Elevation Program (3DEP) effort with other Federal agency partners and the State of Alaska to acquire new statewide Alaska elevation data. Under its Geospatial Products and Services Contract (GPSC), the USGS is contracting with vendors to acquire 5-meter resolution elevation data using Interferometric Synthetic Aperture Radar (InSAR) sensors flown on aircraft.
The goal of the 3D Elevation Program (3DEP) is to complete acquisition of nationwide lidar (Interferometric Synthetic Aperture Radar (IfSAR) in Alaska) in 8 years to provide the first-ever national baseline of consistent high-resolution elevation data—both bare earth and 3D point clouds—collected in a timeframe of less than a decade.
This project focuses on the illegal artisanal and small-scale mining (ASM) of small and low-grade mineral and gemstone deposits. Project scientists employ field mapping, geomorphological techniques, and remote sensing to map, monitor, and evaluate mineral deposits and ASM activities in conflict zones and during complex emergencies.
During 2019, the Avian Radar Project surveyed the migration of birds and bats in the Detroit, Michigan, area using mobile avian radar units.
Tumbesian dry forest in southern Ecuador and northern Peru faces a number of threats from factors such as climate change, wildfire, and intensive livestock grazing that can result in degraded conditions.
An effort for long-term monitoring using Interferometric Synthetic Aperture Radar (InSAR) to recognize, map, and monitor landslide-related deformation over the southern portion of the Green Mountain reservoir was undertaken.
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.
The USGS is leading a 3D Elevation Program (3DEP) effort to coordinate with other Federal agency partners and the State of Alaska to acquire new Alaska elevation data statewide using remote sensing techniques. Under its Geospatial Products and Services Contract (GPSC), the USGS is contracting with vendors to acquire 5-meter (m) resolution elevation data using Interferometric Synthetic Aperture Radar (InSAR) sensors flown on aircraft.
The Northern Rangelands Trust (NRT) is an umbrella organization of 33 community conservancies that stretch across the arid and semiarid landscape of northern Kenya. The NRT conservancies protect iconic species such as elephants, rhino, giraffe, cheetah, Grevy’s zebra, hirola, and oryx while supporting a pastoralist, livestock-dominated region in which people’s livelihoods depend on access to grazing areas.
