DNBR-processed Sentinel-2 MSI image from 2020 with a June 2nd, 2020 and Landsat 8 OLI true color band combination (4,3,2), draped over a Shuttle Radar Topography Mission DEM. The northeast portion of the Cameron Peak Fire in Colorado is displayed. Green indicates areas with low burn severity and orange and red indicate moderate/high burn severity. DNBR maps can be used by stakeholders to identify areas of concern for future restoration and management efforts.  Keywords: Burn Severity, Forest Treatment, Forest Management, Wildfire

Along the Colorado Front Range, the importance of forest management has gained significant attention due to uncharacteristically intense fires that burned late in 2020. The Cameron Peak Fire, the largest in Colorado’s recorded history, and the CalWood Fire collectively burned an estimated...

Modified Normalized Difference Water Index (MNDWI)-processed imagery of Jobos Bay, Puerto Rico, using Landsat 8 OLI data from 2020. In order to detect shoreline change over time, MNDWI was used with thresholding techniques to classify water and land in the area from 1997 to 2020. Dark purple areas show water and yellow represents land. Classifying water and land over the study period allows partners to quantify change and potential impacts of sea level rise.  Keywords: Landsat, MNDWI

Jobos Bay is located on the southern coast of Puerto Rico, which is known for intense hurricane seasons and increased seasonal storm surge. Scientists at Jobos Bay National Estuarine Research Reserve (JBNERR) are concerned that sea level rise will exacerbate...

Blended image of a DEM from NASA’s SRTM, slope processed from the DEM, NLCD 2016 data, and a 2018 Soil Survey Geographic Database from the Natural Resources Conservation Service over the state of South Dakota, showing a section of the Rosebud Sioux Reservation Land. The dominant layer of DEM shows higher elevation in dark red and lower elevation in lighter red to yellow; all these layers help highlight the risk of flooding in this landscape.  Keywords: SRTM, DEM, NLCD, Soil Survey, South Dakota, Indigenous Peoples, Flood Mapping, Flood Risk

In 2019, the Great Plains experienced unprecedented catastrophic flooding. Large flood events are predicted to increase in frequency and severity, posing risks to communities in this region, particularly Tribal Nations. We used Sentinel-1 C-band Synthetic Aperture Radar (C-SAR), imagery from...

(1) Change in vegetation regrowth post-Silver Fire (2013) in Gila National Forest Watershed from 2013-2019 using NBR, calculated from Landsat-8 OLI imagery. Fire area delineated with warm-color scale, yellow and pink represent high and low vegetation regrowth respectively.  (2) NDWI calculated from 2019 Landsat-8 OLI image, emphasizing stream visualization underneath stream vector where dark blue represents high water content. This helps forest managers understand vegetation recovery and how burned areas interact with hydrology of the watershed.  Keywords: Gila National Forest, wildfire, watershed, hydrology, vegetation recovery, NBR, Landsat

Wildfires have the potential to cause devastating and long-lasting impacts on ecological systems. In the Gila National Forest (Gila NF), wildfire events have occurred with increasing frequency and severity over recent years. These disturbances, such as the historic Whitewater Baldy...

Using Landsat and Sentinel to Identify and Detect Giant Cane in Amistad National Recreation Area for Future Invasive Species Land Management

Portions of Amistad National Recreation Area (NRA) are threatened by the presence of an invasive grass species known as giant cane (Arundo donax), which drastically alters riparian habitats by out-competing native vegetation and depleting vital resources. Giant cane does not provide viable habitat or food...

Using NASA Earth Observations and SAR to Enhance Crop Classification Accuracy from Ground Surveys to Larger Scales in the Long Term Agroecosystem Research (LTAR) Network

North Dakota and Georgia are two of the largest commercial agricultural producers in the United States, with a combined crop value of over 11 billion dollars. Agriculture management and sustainability practices—such as irrigation patterns and plant and harvest strategies—are crucial to long-term food security. Crop...

Using NASA Earth Observations and Synthetic Aperture Radar to Enhance Crop Classification Accuracy from Ground Surveys to Larger Scales in the Long Term Agroecosystem Research Network

Each year, the United States Department of Agriculture (USDA) releases a Cropland Data Layer (CDL) that serves as a nationwide classification system and statistical service for the United States agriculture industry. The CDL is compiled using Landsat 8 Optical Land Imager (OLI) and Sentinel-2 Multispectral...

Using NASA Earth Observations to Assist the National Park Service in Assessing Snow Cover Distribution and Persistence Changes in the Sky Islands

Southeastern Arizona is home to unique mountain ranges known as the Sky Islands. Sky islands are biodiversity hotspots and host various ecosystems, ranging from arid deserts to temperate forests. These mountain ecosystems rely on slow-melting snowpack to sustain themselves during dry periods. However, the...
