Locations of Dental Care Providers

This layer displays the locations of all dental health care providers with a CMS National Provider Identifier (NPI). Data are from the Centers for Medicare and Medicaid Services (CMS) August 2019 National Provider Identifier (NPI) downloadable file.

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.

Local Law Enforcement

Law Enforcement agencies “are publicly funded and employ at least one full-time or part-time sworn officer with general arrest powers”. This is the definition used by the US Department of Justice – Bureau of Justice Statistics (DOJ-BJS) for their Law Enforcement Management and Administrative Statistics (LEMAS) survey.

Power Plants

This feature class/shapefile represents electric power plants. Power plants are all the land and land rights, structures and improvements, boiler or reactor vessel equipment, engines and engine-driven generators, turbo generator units, accessory electric equipment, and miscellaneous power plant equipment are grouped together for each individual facility.

Ethanol Plants

This feature class/shapefile represents Ethanol Plants. An Ethanol Plant is a facility that uses various biomass source to produce ethanol for use as a fuel.

Army Corps Floodwalls

This layer displays United States Army Core of Engineers surveyed Floodwalls. The USACE defines an Floodwall as a structure erected to protect areas from high river stages. For more information about USACE data, visit the National Levee Database.

Army Corps Leveed Areas

Electric Substations

This feature class/shapefile represents electric power substations primarily associated with electric power transmission. In this layer, substations are considered facilities and equipment that switch, transform, or regulate electric power at voltages equal to, or greater than, 69 kilovolts. Substations with a maximum operating voltage less than 69 kilovolts may be included, depending on the availability of authoritative sources, but coverage of these features should not be considered complete. The Substations feature class/shapefile includes taps, a location where power on a transmission line is tapped by another transmission line.

Coal Mines

This layer shows the location and production of coal mines within the United States

National Land Cover Dataset

The National Land Cover Database (NLCD) serves as the definitive Landsat-based, 30-meter resolution, land cover database for the Nation. NLCD provides spatial reference and descriptive data for characteristics of the land surface such as thematic class (for example, urban, agriculture, and forest), percent impervious surface, and percent tree canopy cover. NLCD supports a wide variety of Federal, State, local, and nongovernmental applications that seek to assess ecosystem status and health, understand the spatial patterns of biodiversity, predict effects of climate change, and develop land management policy. NLCD products are created by the Multi-Resolution Land Characteristics (MRLC) Consortium, a partnership of Federal agencies led by the U.S. Geological Survey.
