Maps- GIS Data Carousel
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.
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.
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.
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.
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.
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.
