Cyanobacterial blooms are a global concern because they pose a threat to human and aquatic ecosystem health and cause economic damage. Cyanobacteria can produce toxins potent enough to adversely affect the health of humans, pets, livestock, and wildlife. The USGS is collaborating with the U.S.
Multispectral (approx. 4-12 bands)
The USGS National Land Imaging Program (NLIP) has built a long-term capacity to collect and analyze land imaging user requirements to advance the Nation’s operational and science objectives and better serve the land imaging community. The USGS documents the land imaging requirements of U.S.
The USGS Earth Resources Observation and Science (EROS) Center and collaborative agencies in Canada and Mexico have published the first-ever 30-meter resolution consistent land cover product for all of North America.
The National Land Cover Database (NLCD) provides nationwide data on land cover and land cover change at 30-meter (m) resolution. The current version of NLCD has quantified the U.S. land surface for land cover, percent impervious surface, and percent tree canopy cover for three periods: 2001, 2006, and 2011.
The USGS Earth Resources Observation and Science (EROS) Center’s National Land Cover Database team, in collaboration with the Bureau of Land Management (BLM), is producing the most comprehensive remote-sensing-based quantification of western U.S. shrublands to date.
In late May, the Department of the Interior (DOI) announced that the LANDFIRE (Landscape Fire and Resource Management Planning Tools) Program was the recipient of the 2017 DOI "Environmental Dream Team" award. The award recognizes the program team as exceptional environmental champions and agents of change. Led by the DOI and the U.S.
One of the most valuable uses of remote sensing imagery is for mapping and monitoring landscape change, and Landsat-based land cover data such as the National Land Cover Database (NLCD) and the Cropland Data Layer (CDL) from the U.S. Department of Agriculture (USDA) have been used for countless applications.
The USGS project Patterns in the Landscape–Analyses of Cause and Effect (PLACE) is leveraging improvements in image processing capabilities to advance understanding of the driving forces and impacts of landscape change over time.
Invasive buffelgrass (Pennisetum ciliare) spreads easily in the Sonoran Desert ecosystem, where it forms a continuous fuel layer that carries fire across the landscape, threatening native flora and fauna species. Current management of buffelgrass in Saguaro National Park (SNP) includes the targeted application of herbicide, which is most effective when the grass is photosynthetically active.
The recent infestation of an Asian scale insect was blamed for a widespread phragmites (marsh grass) dieback in southeast Louisiana that alarmed resource managers.
