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.
Irrigated Acreage Delineated from Landsat-Derived Maximum Normalized Difference Vegetation Index (NDVI) 1975-2010, Walker River Basin Nevada and California
These data represent the extent and spatial distribution of irrigated acreage delineated from maximum Normalized Difference Vegetation Index (NDVI) derived from Landsat scenes in the Walker River Basin, California and Nevada, at five-year intervals from 1975-2010.
These data present a ground-water inventory of existing geospatial data and other information needed to determine the extent and characteristics of the aquifers in the Tahoe Basin.
Data - Removing roads from the National Land Cover Database to create improved urban maps for the United States, 1992-2011
To better map the urban class and understand how urban lands change over time, we removed rural roads and small patches of rural development from the NLCD developed class and created four wall-to-wall maps (1992, 2001, 2006, and 2011) of urban land.
To investigate the rates, causes, and spatial and temporal patterns of forest harvest on private tracts throughout the Cascade Mountains, we relied on a new generation of annual land-use/land-cover (LULC) products created from the application of the Continuous Change Detection and Classification (CCDC) algorithm to Landsat satellite imagery collected from 1985 to 2014.
StreamStats is a Web application that incorporates a Geographic Information System (GIS) to provide users with access to an assortment of analytical tools that are useful for a variety of water-resources planning and management purposes, and for engineering and design purposes.

New York Hydrologic Conditions Mapper: (1) Streamflow conditions (2) Groundwater conditions (3) Precipitation (4) Precipitation departure from normal (5) NYC Water Supply System Status. In addition, historical monthly conditions reports and seasonal condition maps are also available.
National Assessment of Shoreline Change: A GIS compilation of updated vector shorelines and associated shoreline change data for the north coast of Alaska, U.S. Canadian border to Icy Cape
This data release is an update to the original North Coast of Alaska data and includes revised rate-of-change calculations based on two additional shoreline positions data and improved rate metrics.
