Mapping, Remote Sensing, and Geospatial Data
Data about Earth and its resources are only useful if available in a format that is understandable and accessible. We provide the Nation with ready access to natural science information that supports smart decisions about how to respond to natural risks and manage natural resources.
The Hazard Exposure Reporting and Analytics (HERA) application was developed to provide users with insight on potential population, economic, land cover, and infrastructure vulnerability resulting from a given hazard. Interactive maps and graphics allow users to examine hazard exposure for individual communities, to compare exposure for multiple communities and changes in hazard exposure.
DATA RELEASE - Riparian Vegetation Classification of the Colorado River Corridor, Grand Canyon, Arizona, 2013—Data
These data are classification maps of total riparian vegetation along the Colorado River in Grand Canyon from Glen Canyon Dam to Pearce Ferry in Arizona, and are derived from interpretation of multispectral high resolution airborne imagery acquired in May 2013.
The USGS Global Visualization Viewer (GloVis) is an online search and order tool for selected is an online search and order tool for selected remote sensing data.
GeoMAC is an internet-based mapping application designed to allow Fire Managers and the Public access to dynamically displayed online maps of current fire locations and fire perimeters in the continental U.S. and Alaska. The GeoMAC application is an indispensable tool for aiding fire-personnel by dynamically displaying the most current forest-fire information available from a web browser.
Data from the Global Ecosystems activity allow for a fine resolution inventory of land-based ecological features anywhere on Earth, and contribute to increased understanding of ecological pattern and ecosystem distributions. Ongoing efforts focus on an ecological land classification approach emphasizing ecologically meaningful characteristics of the land, i.e. bioclimate, landform, and lithology.
This dataset consists of modeled projections of land use and land cover and population for the State of California for the period 1970-2101. For the 1970-2001 period, we used the USGS's LUCAS model to "backcast" LULC, beginning with the 2001 initial conditions and ending with 1970. For future projections, the model was initialized in 2001 and run forward on an annual time step to 2100.
Community exposure in California to coastal flooding hazards enhanced by climate change, reference year 2010
The data set contains information on potential population, economic, land cover, and infrastructure flooding exposure for San Francisco Bay and coastal communities of the state of California, USA. This data is viewable on HERA.
The USGS Geo Data Portal (GDP) project provides scientists and environmental resource managers access to downscaled climate projections and other data resources that are otherwise difficult to access and manipulate. This user interface demonstrates an example implementation of the GDP project web-service software and standards-based data integration strategy.
DATA RELEASE - Four Band Image Mosaic of the Colorado River Corridor in Arizona--2013, including Accuracy Assessment Data
The imagery data are airborne multispectral high resolution data for the Colorado River in Grand Canyon in Arizona, USA. The data consist of four bands (blue, green, red and near infrared) with a ground resolution of 20 centimeters (cm). These data are available to the public as 16-bit geotiff files.
The LandsatLook Viewer is a prototype tool that was developed to allow rapid online viewing and access to the USGS Landsat image archives.
The USGS FEWS NET Data Portal provides access to geo-spatial data, satellite image products, and derived data products in support of FEWS NET drought monitoring efforts throughout the world. This portal is provided by the USGS FEWS NET Project, part of the Early Warning Focus Area at the USGS Earth Resources Observation and Science (EROS) Center.
The National Land Cover Database (NLCD) provides nation-wide data on land cover and land cover change at the Landsat Thematic Mapper (TM) 30-meter resolution. NLCD provides spatial reference and descriptive data for characteristics of the land surface such as thematic class (e.g., urban, agriculture, and forest), percent impervious surface, and percent tree canopy cover.
