  1. Title: Hectacres Occupied by Pasturelands and Feed Crops

    Contributors:

    Summary: This multi-band raster data represents hectacres of pastureland that are currently occupied by feed crops. The pixel band ranges represent two estimated values: areas sourced from the lowest carbon areas and areas sourced from the highest carbon areas. The data is captured at a resolution of 5 arcminutes over the global domain. This data is released with an Attribution 4.0 International (CC BY 4.0) license. Users may cite this collection with https://doi.org/10.17609/q5pe-7r68/.

  2. Title: Carbon Opportunity Cost of Present-Day Pasturelands and Animal Feed Crops

    Contributors:

    Summary: This multi-band raster data represents estimates of carbon opportunity cost. The data is captured at a resolution of 5 arcminutes over the global domain and is derived from data collected approximately over the past two decades (2000-2020). The pixel values measure estimates in tonnes of potential vegetation per hectare that are suppressed by pasturelands and present-day feed crops. The bands represent three estimates of carbon in potential vegetation: median, low (5th percentile), and high (95th percentile). This data is released with an Attribution 4.0 International (CC BY 4.0) license. Users may cite this collection with https://doi.org/10.17609/q5pe-7r68/.

  3. Title: Geologic Units (Polygons): Geology of the Conterminous United States, 2005

    Contributors:

    Summary: This polygon shapefile shows the boundaries of geologic units within the United States. This layer is part of the Geologic Map of the United States, originally published at a scale of 1:2,500,000 (King and Beikman, 1974b). It excludes Alaska and Hawaii. These data depict the geology of the bedrock that lies at or near the land surface, but not the distribution of surficial materials such as soils, alluvium, and glacial deposits. This is a revised version of the April 2004 data set. This map complements the Generalized Geologic Map of Alaska, Hawaii, Puerto Rico, and the U.S. Virgin Islands by Reed and Bush. A geographic information system (GIS) allows combining and overlaying of layers for analysis of spatial relations not readily apparent in the standard paper publication. This layer is part of the 1997-2014 edition of the National Atlas of the United States. Conversion of the geologic map of the U.S. to a digital format was undertaken to facilitate the presentation and analysis of earth-science data. Digital maps can be displayed at any scale or projection, whereas a paper map has a fixed scale and projection. However, these data are not intended to be used at any scale finer than 1:2,500,000.

  4. Title: Outlines of Major Calderas and Impact Structures: Generalized Geologic Map of the Conterminous United States, 2005

    Contributors:

    Summary: This line shapefile shows the outlines of major calderas and impact structures in the United States. A caldera is a large, generally circular depression at the summit of a volcano formed when magma is withdrawn or erupted from a shallow underground magma reservoir. An impact structure is a crater formed by the impact of a meteoroid, asteroid, or comet with the Earth.This layer is part of a Generalized Geologic Map of the United States, originally published at a scale of 1:2,500,000 (King and Beikman, 1974b).

  13. Title: Global GIS : Geology of the conterminous United States at 1:2,500,000 scale : Geology

    Contributors:

    Summary: This datalayer is a polygon coverage representing geologic regions of the conterminous United States. It is a digital version of the geology features of H.M. Beikman and P.B. King's Geologic Map of the United States, originally published at a scale of 1:2,500,000 (1974). This version of the datalayer was published as part of the USGS Global GIS : global coverage database (2003). The USGS Global GIS database contains a wealth of USGS and other public domain data, including global coverages of elevation, landcover, seismicity, and resources of minerals and energy at a nominal scale of 1:1 million. The U.S. Geological Survey (USGS) and The American Geological Institute (AGI) announced a cooperative agreement that will focus on making the USGS Global Geographic Information System (GIS) database readily available to educators and the general public in the form of a DVD based world atlas.
