GIS Data
USGS is a primary source of geographic information system (GIS) data. Our data and information is presented in spatial and geographic formats, including The National Map, Earth Explorer, GloVIS, LandsatLook, and much more.
The National Map
The National Map is a collaborative effort among the USGS and other Federal, State, and local partners to improve and deliver topographic information for the Nation. It has many uses ranging from recreation to scientific analysis to emergency response. The National Map is easily accessible for display on the internet, as products and services, and as downloadable data.
Water Quality Data Viewer for New York
U.S. Geological Survey (USGS) scientists are leading a diverse range of studies to address CyanoHAB issues in water bodies throughout the United States, using a combination of traditional methods and emerging technologies, and in collaboration with numerous partners.
National Biogeographic Map
The National Biogeographic Map (NBM) is a project of the Core Science Systems Mission Area. The project’s goal is to provide a platform for analysis of questions about what species are where, how well protected they are, how vulnerable they are to stressors, and what management options will have the greatest benefit for conservation of biodiversity.
California Groundwater Model Archive
The USGS models shown on this site are in the public domain, and are freely available. They are based on MODFLOW and other public-domain USGS software. Links to publications and web resources associated with each model are shown in the table next to the model map. The associated model files for some of these models are currently available via download.
Telemetry of Cinnamon Teal Tagged in Sacramento NWR
Scientists at WERC's Dixon Field station have fitted Cinnamon Teal with GPS backpacks. Using R, the telemetry locations are displayed on an image every two weeks.
Edwards and Trinity Geology in Parts of South Central Texas
Groundwater flow and storage in the Edwards and Trinity aquifers are largely controlled by the geologic structure and hydrostratigraphy in the region. To help local agencies and stakeholders to more effectively manage the regional water resources, a better understanding of the spatial distribution of the geologic framework and hydrostratigraphic units of the aquifers is needed.
