Data and Tools

Science Datasets

The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

DATA RELEASE - Automated Reference Toolset (ART)

These environmental raster covariate, geospatial vector data, and tabular data were compiled as input data for the Automated Reference Toolset (ART) algorithm. These data are a subset of all the environmental raster covariate data used in the ART algorithm.

DATA RELEASE - Full Annual Cycle Bioenergetics Model of Migration Applied to Galapagos Tortoises

Data on ambient-shade temperature, Normalized Difference Vegetation Index (NDVI) between February 1, 2010 and January 31, 2011 used for input onto a bioenergetics-based movement model for Galapagos turtles.

DATA RELEASE - Geomorphic Process from Topographic Form

These data were used for the development and validation of the automated workflow for mechanistic segregation of geomorphic transport mechanisms presented in the manuscript "Geomorphic Process from Topographic Form: Automating the Interpretation of Repeat Survey Data in River Valleys."

DATA RELEASE - Plant Functional Traits, Colorado River, Grand Canyon, 2012-2014

Data were compiled or measured (depending on the trait) for 110 plant species which were documented in vegetation monitoring surveys in years 2012-2014 along the Colorado River through Grand Canyon National Park. New trait data were collected for specific leaf area, stem specific gravity, δ13C, δ15N, percent carbon and nitrogen, and carbon:nitrogen ratio.

Borehole Temperature Logs from Arctic Alaska, pre-1989

The Borehole Temperature Logs provide temperature measurements acquired in permafrost regions of arctic Alaska between 1950 and 1988 by the USGS at 87 sites deep enough to penetrate the base of permafrost.

Geologic Map of North America

The Geologic Map of North America portrays the grand architecture of the continent as we understood it in the closing years of the 20th century (The Geological Society of America, Inc., 2005). It is the final product of the Geological Society of America's Decade of North American Geology project, and covers about 15% of the Earth's surface at a scale of 1:5,000,000.

Global Ecosystems

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.

USGS/NOAA North American Packrat Midden Database

The USGS/NOAA North American Packrat Midden Database makes thousands of identified specimens and hundreds of published reports available in a standardized, quality-controlled format. This version offers the most comprehensive, high-quality archive of midden data available for North America, and facilitates Quaternary paleoenvironmental studies on a range of local to regional scales.

Hawai‘i Volcanoes National Park Landbird Surveys 2015-2016

Hawaiʻi Volcanoes National Park was surveyed for landbirds and landbird habitat from February through April 2015 and February through April 2016. This information provides the second datum in the time-series of Pacific Island Network (PACN) monitoring for long-term trends in landbird distribution, density, and abundance (initial surveys conducted in 2010). Report available.

North American Breeding Bird Survey Dataset 1966 - 2016, version 2016.0

The 1966-2016 North American Breeding Bird Survey dataset contains avian point count data for more than 700 North American bird taxa (species, races, and unidentified species groupings).  These data are collected annually during the breeding season, primarily June, along thousands of randomly established roadside survey routes in the United States and Canada.

California Land-change Projections

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.
