This database contains the records previously provided in the Mineral Resource Data System (MRDS) of USGS and the Mineral Availability System/Mineral Industry Locator System (MAS/MILS) originated in the U.S. Bureau of Mines, which is now part of USGS. The MRDS is a large and complex relational database developed over several decades by hundreds of researchers and reporters. This product is a digest in which the fields chosen are those most likely to contain valid information.
ACS 13-17 Self Response Score
This layer displays areas defined as Hard to Count by the United States decennial census. Data is from the US Census Planning Database and included 2010 Response Rates, Mail Return Rates, Low Response Score, and ACS Response Rates. Learn more about US Census Hard to Count areas.
Coal Mines
This layer shows the location and production of coal mines within the United States
2010 Census Low Response Score
This layer displays areas defined as Hard to Count by the United States decennial census. Data is from the US Census Planning Database and included 2010 Response Rates, Mail Return Rates, Low Response Score, and ACS Response Rates. Learn more about US Census Hard to Count areas.
Locations of Primary Care Physicians
This layer displays the locations of all primary care physicians with a CMS National Provider Identifier (NPI). Primary care physicians are those MDs or DOs specializing in family practice, general practice, pediatric medicine, or internal medicine. Data are from the Centers for Medicare and Medicaid Services (CMS) August 2019 National Provider Identifier (NPI) downloadable file.
2010 Census Mail Return Rate
This layer displays areas defined as Hard to Count by the United States decennial census. Data is from the US Census Planning Database and included 2010 Response Rates, Mail Return Rates, Low Response Score, and ACS Response Rates. Learn more about US Census Hard to Count areas.
Coal Fields
This data set shows the coal fields of Alaska and the conterminous United States. Most of the material for the conterminous United States was collected from James Trumbull’s “Coal Fields of the United States, Conterminous United States” map (sheet 1, 1960). The Gulf Coast region was updated using generalized, coal-bearing geology obtained from State geologic maps. The Alaska coal fields were collected from Farrell Barnes’s “Coal Fields of the United States, Alaska” map (sheet 2, 1961).
Wind Turbine Density
This layer was created using point data of Wind Turbine locations within the U.S. from USGS. Density was calculated using a circular neighborhood of 1 mile and each cell is 1 square mile in area.
Crude Oil Pipelines
This layer represents crude oil pipelines throughout the U.S. and part of Canada.
Watershed Boundary Dataset, 2-Digit Hydrologic Units
The 2-Digit Hydrologic Units, a component of the Watershed Boundary Dataset (WBD), depict the major water resource regions of the United States. A water resource region is the first level of classification used by the United States Geological Survey to divide and sub-divide the United States into successively smaller hydrologic units. This first level of classification divides the United States into 22 major geographic areas, or regions. These geographic areas contain either the drainage area of a major river or the combined drainage areas of a series of rivers.
