Analyzing North American Glacier Change

Submitted by atripp on

Mountain glacier mass change affects water resources, regional ecosystems and global sea level. Understanding the physical processes that control glacier mass change requires field measurements of winter snow accumulation and summer melt. Yet field measurements only capture discrete points across the glacier surface, which can result in systematic bias.

Katahdin Woods and Waters National Monument 4-Band Aerial Collection

Submitted by atripp on

The primary objectives of the Katahdin Woods and Waters National Monument (KAWW),Maine, mapping project were to provide the following: an accurate, tested, and up-to-date vegetation map; a vegetation classification standardized to the U.S. National Vegetation Classification and supported by vegetation plot data collected within the Monument; and a field key to vegetation for the entire monument.

Developing Bare-Earth Digital Elevation Models from Structure from Motion Data on Barrier Islands

Submitted by atripp on

Barrier islands are dynamic environments. Under calm conditions, they are gradually shaped by currents, waves, and tides; during hurricanes and other extreme storms, they can evolve within hours to days. Unmanned aircraft systems (UAS) can collect monitoring data, especially elevation information, via Structure from Motion (SfM) techniques, with a temporal resolution that is well-suited for these dynamic environments.

The Vegetation Mapping Project of Everglades National Park and Big Cypress National Preserve

Submitted by atripp on

The Everglades National Park (EVER) and Big Cypress National Preserve (BICY) vegetation mapping project is part of the Comprehensive Everglades Restoration Plan, a cooperative effort between the South Florida Water Management District, the U.S. Army Corps of Engineers (USACE), and the NPS Vegetation Mapping Inventory Program (VMI).

Monitoring of Permafrost Thaw Erosion Features

Submitted by atripp on

The NPS Arctic Inventory and Monitoring Network (ARCN) is using high-resolution satellite images and historical color infrared aerial photographs to monitor the abundance of small landslides resulting from thaw of permafrost. Active-layer detachments (ALD) and retrogressive thaw slumps (RTS) are small landslides that occur as a result of thaw in permafrost regions.
