This layer displays United States Army Core of Engineers surveyed Embankments. The USACE defines an Embankment as the area of a floodplain from which flood water is excluded by the levee system. For more information about USACE data, visit the National Levee Database.
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.
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.
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.
This layer displays United States Army Core of Engineers surveyed Leveed Areas. The USACE defines a Levee Areas as the area of a floodplain from which flood water is excluded by the levee system. For more information about USACE data, visit the National Levee Database.
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.
The U.S. natural gas pipeline network is a highly integrated network that moves natural gas throughout the continental United States. The pipeline network has about 3 million miles of mainline and other pipelines that link natural gas production areas and storage facilities with consumers. In 2017, this natural gas transportation network delivered about 25 trillion cubic feet (Tcf) of natural gas to 75 million customers.
About half of the existing mainline natural gas transmission network and a large portion of the local distribution network were installed in the 1950s and 1960s because consumer demand for natural gas more than doubled following World War II. The distribution network has continued to expand to provide natural gas service to new commercial facilities and housing developments.
This layer was created using point data of Oil and Natural Gas wells in the United States. An Oil and Natural Gas Well is a hole drilled in the earth for the purpose of finding or producing crude oil or natural gas; or producing services related to the production of crude or natural gas. Density was calculated using a circular neighborhood of 1 mile and each cell is 1 square mile in area.
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.
This layer shows the location of electricity generating power-plants in the U.S., the total capacity of each plant, and the primary fuel source.
