Quantifying Change in Woodland Canopy Cover

Submitted by atripp on Wed, 06/09/2021 - 10:34

The San Carlos Apache Tribe in Arizona wants to learn more about the historical characteristics of their woodlands, savannas, and grasslands so they have a target for restoration efforts. Restoring juniper woodland to savanna is a focus of the Tribe’s intensive management activities, and spatial information that would help determine where best to attempt restoration is needed.

Analyzing North American Glacier Change

Submitted by atripp on Tue, 06/08/2021 - 15:01

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.

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 Thu, 06/03/2021 - 09:57

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.
