USGS is a primary source of Geographic Information Systems (GIS) Data. Our data and information is presented both spatially and geographically including The National Map, Earth Explorer, GloVIS, LandsatLook, and much more. Start exploring by topic below.
The layers within this geodataset describe physical habitat characteristics in the North and South Fork Shenandoah rivers. They represent conditions during summer low-flow periods when canoeing was possible.The data are derived from GPS field surveys and GIS editing to commplete habitat units around islands or river bends.
The seismic-landslide probability map covers the counties of Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Santa Cruz, Solano, and Sonoma. The slope failures are triggered by a hypothetical earthquake with a moment magnitude of 7.0 occurring on April 18, 2018, at 4:18 p.m. on the Hayward Fault in the east bay part of California’s San Francisco Bay region.
Liquefaction potential as a result of HayWired earthquake scenario mainshock (April 18, 2018) shaking in Alameda and Santa Clara Counties, San Francisco Bay area, California
These data are a geospatial representation of liquefaction potential for the HayWired earthquake scenario, a magnitude 7.0 earthquake occurring on the Hayward Fault on April 18, 2018, with an epicenter in the city of Oakland, CA. These data are the product of an analysis that created a detailed liquefaction probability map covering the northern Santa Clara County and western Alameda County...
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.

Application of Wind Fetch and Wave Models for Habitat Rehabilitation and Enhancement Projects - 2012 Update
Models based upon coastal engineering equations have been developed to quantify wind fetch length and several physical wave characteristics including significant height, length, peak period, maximum orbital velocity, and shear stress.
This viewer provides visualization for and accessibility to USGS lidar data obtained following Hurricane Sandy (October 2012). Access and download data and publications that include the source lidar data and the coastal dune and shoreline data needed to examine coastal change and erosion hazards.
