National Land Imaging Program Requirements, Capabilities and Analysis Activities

Submitted by atripp on Mon, 12/10/2018 - 13:21

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.

Alaska Interferometric Synthetic Aperture Radar (InSAR) Elevation Data Status

Submitted by atripp on Mon, 12/10/2018 - 09:06

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.

Tracking Rangeland Condition for Sustainable Management in Kenya

Submitted by atripp on Thu, 12/06/2018 - 13:18

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.

Great Lakes Remote Sensing—Wetlands

Submitted by atripp on Mon, 12/03/2018 - 10:12

In the Great Lakes Basin, wetlands are considered to be the most vulnerable landscape feature subject to human actions and climate change.  The wetlands are part of the water infrastructure and provide flood storage, storm surge protection, carbon storage, clean water, and unique fish and wildlife habitats.  The public and wetland managers are asking for more frequent updates of wetland and adjacent habitat change.  Monitoring wetlands seasonally is

Population at Risk Studies for Dam Failure Loss of Life Analysis

Submitted by atripp on Fri, 11/30/2018 - 14:47

BOR Population at Risk studies are used to determine the possible magnitude of loss of life in the event of a dam failure. Inundation extent, population at risk, and life loss estimation are the three components commonly considered in failure consequences. Remotely sensed data play a major role in determining population locations and densities.

Identification of Deformation in Paradox Valley Using InSAR

Submitted by atripp on Fri, 11/30/2018 - 14:30

The BOR operates the Paradox Valley Unit (PVU), a salinity control project located at Paradox Valley in western Colorado that helps to minimize water degradation in the Colorado River. PVU diverts up to 90% of the naturally occurring brine groundwater in Paradox Valley, preventing it from entering the Dolores River.
