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.
Where are most important places to direct conservation effort? Such a simple question is not answered simply. There are a myriad of priorities, constraints, and capacities, both scientific and socio-economic, which in combination guide the allocation of management effort. An honest accounting of these priorities, constraints, and capacities is essential for efficient, effective action.
- Allows managers and planners to rapidly assess landscape attributes and link these attributes with species/habitat information
- Provides resource managers a means to compare the conservation potential of local management units with that of the surrounding county, state, or region
- Can be applied to any taxa or suite of taxa and any landscape, given that spatial data. ...
- The Split By Attribute Tool is a customization of ArcMap.
- The tool takes a single shapefile and splits it into many shapefiles based on the unique values of a chosen field.
- If the user has made a selection on a shapefile, then only those features that have been selected will be split.
- Each output layer will named with the following structure: user supplied base ...
The Upper Mississippi River Restoration (UMRR) Program Long Term Resource Monitoring (LTRM) element has collected millions of records of information over 20+ years. Fisheries, water quality, vegetation, and invertebrates have all been sampled. Geographic locations were collected for all sampling points.
This dataset includes spatial locations in the Pacific Northwest where streamflow observations were recorded. For the purpose of this investigation, all streamflow observations were converted into wet or dry indicator values.
Approximate locations and short descriptions of mines, deposits, and districts where critical minerals are found. The critical minerals are discussed in USGS Professional Paper 1802, and many of these locations are described in further detail in that report.
Evapotranspiration units and potential areas of groundwater discharge delineated July 20–24, 2009 in the upper Humboldt River Basin, northeastern Nevada
The data set consists of 2 separate items for the upper Humboldt River Basin:
1. evapotranspiration units
2. potential areas of groundwater discharge
Groundwater-level and groundwater-level change contours for the Lahontan Valley shallow aquifer near Fallon, Nevada, 2012
One dataset contains contours representing water levels based on depth-to-groundwater measurements made at 98 wells in July 2012 in the Lahontan Valley. The second dataset contains contours representing water level change in the shallow aquifer in Lahontan Valley from 1992-2012 based on depth-to-groundwater measurements made in 73 wells in 1992 and 2012, with limited measurements made in 2013...
Groundwater discharge areas for the 14 hydrographic areas in the middle Humboldt River Basin, north-central Nevada
This data set contains polygons representing the groundwater discharge areas for the 14 hydrographic areas in the middle Humboldt River Basin, north-central Nevada.
This digital raster dataset represents depth to pre-Cenozoic bedrock in northern Nevada as published in Chapter 6: Geophysical Methods and Application in U.S. Geological Survey Bulletin 2218, Assessment of Metallic and Mineral Resources in the Humboldt River Basin, Northern Nevada by D.A. Ponce.
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.
