Burn severity mapping is commonly informed by changes in vegetation spectral response; the Monitoring Trends in Burn Severity program, for instance, relies on pre- and post-fire Landsat image pairs to delineate and characterize fire severity.
Multispectral (approx. 4-12 bands)
Optical satellite observations were used to quantify ground-surface displacements resulting from the 2019 Ridgecrest, California, earthquakes. Specifically, optical images from WorldView-1, WorldView-2, and WorldView-3 collected before and after the 2019 Ridgecrest earthquakes were accessed via the ©NextView license.
Sagebrush ecosystems provide valuable services to society, including recreational and economic opportunities like hunting and fishing, energy development, and livestock grazing. Sagebrush ecosystems also provide habitat for wildlife, natural systems for carbon sequestration, and resources for human habitation.
How bad can these drought conditions get? How much hay should I buy? How many animals should I sell or relocate to another area with a forage surplus? Land managers face these questions during a drought. Livestock operations are often restricted to dry areas with unreliable rainfall, which are generally less suitable for farming.
Migratory birds are highly dependent on major moist soil seed (MSS) as a food resource in the Central Valley of California, a major North American flyway.
Winter cover crops are an effective management practice for taking up residual nitrogen in the soil after summer crops are harvested, thereby reducing nitrogen losses to groundwater and soil loss to erosion.
During the COVID-19 pandemic, the majority of OSMRE employees have easily transitioned into a maximum telework schedule as much work can be done remotely. With technology in place to stay in contact and have virtual meetings, they continue to work successfully on collaborative assignments.
The OSMRE GIS Branch has been providing imagery support to monitor mine reclamation activities. This support was more critical in 2020 due to travel restrictions caused by the pandemic.
Dramatic warming in the Arctic is accelerating the melting of snow and ice. The NPS Arctic Inventory and Monitoring Network (ARCN) is using Landsat satellite images to monitor the area of lakes and ponds in the five NPS units in northern Alaska. Water surface area trends were computed using both the new U.S.
Caribou (Rangifer tarandus) are an iconic species of the north and an integral component of the natural ecosystem and socioeconomic wellbeing of local communities. Alaska is home to 32 different caribou herds which are identified by females returning to specific calving areas each spring to give birth.
