Continental African sand mining detection data used in 'Continental Mapping Of African Sand Mining Shows Contrasting Links To Urban Development'

Sediments off the eastern United States vary markedly in texture - the size, shape, and arrangement of their grains. However, for descriptive purposes, it is typically most useful to classify these sediments according to their grain-size distributions. Starting in 1962, the U.S. Geological Survey (USGS) and the Woods Hole Oceanographic Institution (WHOI) began a joint program to study the marine geology of the continental margin off the Atlantic coast of the United States. As part of this program and numerous subsequent projects, thousands of sediment samples were collected and analyzed for particle size. The sediment map of the Continental Margin Mapping Program (CONMAP) series is a compilation of grain-size data produced in the sedimentation laboratory of the Woods Hole Science Center (WHSC) of the Coastal and Marine Geology Program (CMGP) of the U.S. Geological Survey (USGS) and from both published and unpublished studies. Sediment was classified using the Wentworth (1929) gr ...

The Federal Emergency Management Agency (FEMA) required high accuracy classified LiDAR data in combination with raster digital elevation models and hydrographic breaklines. For this effort, Continental Mapping Consultants (Continental) collected and processed high accuracy classified LiDAR data in .LAS format as well as a combination of raster digital elevation models.

The data on this CD consist of geographic information system (GIS) coverages and tabular data on the geology of Early Proterozoic and Archean rocks in part of the Early Proterozoic Penokean orogeny. The map emphasizes metasedimentary and metavolcanic rocks that were deposited along the southern margin of the Superior craton and were later deformed during continental collision at about 1850 Ma. The area includes the famous iron ranges of the south shore region of the Lake Superior district. Base maps, both as digital raster graphics (DRG) and digital line graphs (DLG) are also provided for the convenience of users. The map has been compiled from many individual studies, mostly by USGS researchers, completed during the past 50 years, including many detailed (1:24,000 scale) geologic maps. Data was compiled at 1:100,000 scale and preserves most of the details of source materials. This product is a preliminary release of the geologic map data bases during ongoing studies of the geology and metallogeny of the Penokean continental margin. Files are provided in three formats: Federal Spatial Data Transfer format (SDTS), Arc export format (.e00) files, and Arc coverages. All files can be accessed directly from the CD-ROM using either ARC/INFO 7.1.2 or later or Arc View 3.0 or later software. ESRI's Arc Explorer, a free GIS data viewer also provides display and querying capability for these files.

World Continents represents the boundaries for the continents of the world. It provides a basemap layer of the continents, delivering a straightforward method of selecting a small multicountry area for display or study.This layer is best viewed out beyond a scale of 1:3,000,000. The original source was extracted from the ArcWorld Supplement database in 2001 and updated as country boundaries coincident to regional boundaries change. To download the data for this layer as a layer package for use in ArcGIS desktop applications, refer to World Continents.

This historic paper map provides an historical perspective of the cultural and physical landscape during this time period. The wide range of information provided on these maps make them useful in the study of historic geography. As this map has been georeferenced, it also can be used as a background layer in conjunction with other GIS data.

Binary raster dataset (.txt format) containing flood susceptibility maps related to 100-year river floods occurring in the continental U.S. These mapping products were derived through terrain analysis and a technique of pattern classification performed on DEMs obtained from HydroSHEDS (http://hydrosheds.cr.usgs.gov/overview.php) with a 3 arc-second resolution (0.00083333 degree, approximatively 90 m at the equator). Specifically, the flood-prone areas were identified by applying a linear binary classifier based upon the Geomorphic Flood Index (Manfreda et al., 2015; Samela et al., 2015; Samela et al., 2016 ). The raster maps have a 90 m resolution and are geo-referenced. The coordinate system of the maps is UTM (Universal Transverse Mercator) Zone 17N, the projection is Transverse Mercator, and the geodetic system is NAD (North American Datum) 1983. To simplify the management and the use of the data, the continental U.S. was divided into eighteen major water resources regions according to the hydrologic units identified by the United States Geological Survey.

Homeland Infrastructure Foundation-Level Data (HIFLD) geospatial data sets containing information on Outer Continental Shelf (OCS) Protraction Diagrams & Leasing Maps.

The purpose of the CONMAPSG sediment layer is to show the sediment grain size distributions. The maps depicted in this series are old and do not accurately depict small-scale sediment distributions or sea-floor variability. This data layer is supplied primarily as a gross overview and to show general textural trends.

This data set contains the Submerged Lands Act (SLA)boundary line (also known as the State Seaward Boundary (SSB) and Fed State Boundary) for the BOEM Pacific Region in ESRI ArcGIS shape file format. The SLA defines the seaward limit of a state owned submerged lands and the landward boundary of federally managed Outer Continental Shelf (OCS) lands. In the BOEM Pacific Region the SLA is projected 3 nautical miles offshore from the coastal baseline. Further information on the SLA and development of this line from baseline points can be found in OCS Report BOEM 99-0006: Boundary Development on the Outer Continental Shelf. The SLA boundary was developed using nautical charts, topographic maps, and hydrographic surveys to identify coastal baseline points. For California, there was a wide range of map scales used (1:200 – 1:100,000). The Minerals Management Service (MMS - the predecessor bureau to BOEM) used mapping software that was developed in-house to mathematically project the SLA boundary 3 nautical miles seaward from the baseline. For purposes of the SLA, all coordinates are assumed as absolute values with a precision of three decimals of a meter. For purposes other than the SLA, the actual positional precision for a scale of 1:40,000 is approximately 23 meters. In 1992, MMS adopted NADCON v.2.00 or better as the bureau standard horizontal datum transformation software, and reiterated that, for its purposes, “the World Geodetic System of 1984 (WGS 84) is considered equivalent to NAD 83 offshore of Alaska and the conterminous United States.” 57 Fed. Reg. 5168 (February 12, 1992). On December 24, 2014, the SLA boundary offshore of California was fixed (permanently immobilized) by a decree issued by the U.S. Supreme Court. United States v. California, 135 S. Ct. 563 (2014). For a detailed discussion on the fixing of the SLA boundary for California, please see http://www.boem.gov/Oil-and-Gas-Energy-Program/Mapping-and-Data/Multi-Purpose-Marine-Cadastre-Map-Viewer/Court-Decisions.aspx Because GIS projection and topology functions can change or generalize coordinates, these GIS shape files are NOT an OFFICIAL record for the exact Submerged Lands Act Boundary.The official record is reflected through the coordinates listed in the decree, and the boundary shown on the BOEM Supplemental Official Block Diagrams, which are available at http://www.boem.gov/Oil-and-Gas-Energy-Program/Mapping-and-Data/Pacific.aspx

One main challenge in environmental and ecological research is to map land use, the human intent to modify the earth's cover, using satellite data. We have mapped forest management, a land use, in the southeastern and northwestern United States, 1.5 million square kilometers, at high spatial. This is a novel study using spectral time series analysis, expert derived training data and a random forest classifier to map forest management, calculate probability and uncertainty of class membership.
