NPS | 2018
Snowmelt and rain-on-snow (ROS) events enhance the liquid water content of a snowpack, which affects snow properties such as depth, density, grain size, and extent. These changes are associated with…
NPS | 2018
The NPS is using the entire Landsat 30-meter resolution data archive (1980s to the present) to study changes in the total surface area of lakes and ponds in the national parks of northern and central…
NPS | 2018
The NPS contracted with ABR, Inc., to develop a map that depicts the day of the year that a Landsat 30-meter pixel becomes snow free during the spring from 1999 to 2015. Annual coverage is…
NPS | 2018
The Everglades National Park (EVER) and Big Cypress National Preserve (BICY) vegetation mapping project is a component of the Comprehensive Everglades Restoration Plan (CERP). The CERP is a…
NPS | 2018
Snow cover strongly influences the energy budget and regional climate of higher latitudes and elevations. The seasonal freeze-thaw (FT) transition is coupled with snowpack melt dynamics and impacts…
OSM | 2018
The OSMRE Western Region worked with the State of Utah Division of Oil, Gas, and Mining to monitor reclamation efforts at Cottonwood-Wilberg Mine in Emery County, Utah, using remote sensing change…
OSM | 2018
Geographers and remote sensing specialists at OSMRE use unmanned aircraft systems (UAS; drones) to capture images and create mathematically correct 2D and 3D models of active and abandoned coal…
USGS | 2018
Enceladus has active eruptions of water ice that create and sustain the famous rings of Saturn. The jets of water are fed from a global ocean hidden underneath a thick shell of ice. …
USGS | 2018
The USGS has been working with the HiRISE (High Resolution Imaging Science Experiment) team to locate the most promising deposits of water ice for future human colonies on Mars. By carefully…
USGS | 2018
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…
USGS | 2018
Barrier islands provide numerous invaluable ecosystem services, including storm protection and erosion control for the mainland, habitat for fish and wildlife, salinity regulation in estuaries,…
USGS | 2018
The lack of Pacific Islands topographic (land elevation) and bathymetric (water depth) information led Department of the Interior (DOI) researchers to use advanced remote sensing technologies to…
