  1. 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.

    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 A caldera is a large, generally circular depression at the summit of a volcano formed when magma is withdrawn or erupted from a shallow underground magma reservoir.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).

  11. 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.

  14. Title: Land Cover Change, Southwest Cameroon, 2000-2015

    Contributors:

    Summary: This raster dataset is a georeferenced image containing land cover change classifications in southwest Cameroon between 2000 and 2015. Classifications are divided into 3 types of land cover change: unclassified (no change), non-forest (other) to oil palm/immature monoculture, and forest to oil palm/immature monoculture. These data are referenced in the corresponding publication: Ordway et al. 2018. Oil palm expansion and deforestation in Southwest Cameroon associated with proliferation of informal mills. Nature Communications. These data are intended for researchers, students, and policy makers for reference and mapping purposes, and may be used for basic applications such as viewing, querying, and map output production.

  17. Title: Geology, New York State, 1974

    Contributors:

    Summary: This dataset is a digital representation of the King and Beikman map. In 1974 the U.S. Geological Survey published a new Geologic Map of the United States (exclusive of Alaska and Hawaii) on a scale of 1:2,500,000, which was compiled between 1967 and 1971 by Philip B. King and Helen M. Beikman, with geologic cartography by Gertrude J. Edmonston. (from King and Beikman, 1974b) The map displays the rocky foundations on which our of investigation of this foundation by a succession of geologists. It is thus a reference work that present and future geologists of the country can consult and is of prime importance in the education of earth scientists in schools and colleges. Further, it can be consulted by geologists in other countries and continents who wish to learn about the geology of the United States; they will compare the map with similar national or continental maps of their own countries. In terms of resources useful to man, the Geologic Map lays out accurately the major regions of bedrock in New York State upon which many facets of our economy depend. It illustrates the areas of stratified rocks that are the sources of most of our fuels, and the areas of crystalline, plutonic, and volcanic rocks that contain important parts of mineral wealth. The map shows areas of complex folding and faulting, parts of which are still tectonically unstable and subject to earthquake hazards. To some extent the bedrock represented on the map also influences surface soils, which are of interest in agriculture and engineering works. Beyond this, the practical value of the map is less tangible, although it can be an important tool for the discerning user. Clearly, the map will not pinpoint the location of the next producing oil well or the next bonanza mine, nor will it give specific advice for the location of a dam or reactor site; these needs can only be satisfied by maps on much larger scales, designed for specific purposes. Nevertheless, the sapient exploration geologist can find upon it significant regional features not apparent to the untrained user. Many great petroleum pools occur in stratigraphic traps, or "wedge belts of porosity," caused by overlap or truncation, the regional occurrence of which can be seen on the map. Important mineral deposits cluster along regional tectonic trends or chains of plutons of specific ages. Finally, the Geologic Map will be used in national planning activities in conjunction with other national maps showing environmental features such as climate, vegetation, and land use --for the location of power transmission corridors, highways, National Parks, wilderness areas, reclamation projects, and the like.
