The shapefile format is a geospatial vector data format for geographic information system (GIS) software. It is developed and regulated by Esri as a mostly open specification for data interoperability among Esri and other GIS software products . [ 1 ]

Locate maps and geographic data content for a particular part of the state or search based on keyword or theme type. [12] Kentucky Open Data Portal
This mismatch was not possible when the census TIGER files were available in ASCII format that was topological unlike shapefiles. The Census Bureau has made the data available through WMS servers. [4] The data forms a base for OpenStreetMap in the US, and also was used for the initial import of US map data into the Waze navigation system.
The United States National Grid (USNG) is a multi-purpose location system of grid references used in the United States. It provides a nationally consistent "language of location", optimized for local applications, in a compact, user friendly format.
Currently, the best source for nationwide LiDAR availability from public sources is the United States Interagency Elevation Inventory (USIEI). [1] The USIEI is a collaborative effort of NOAA and the U.S. Geological Survey, with contributions from the Federal Emergency Management Agency, the Natural Resources Conservation Service, the US Army Corps of Engineers, and the National Park Service.
Map of the Megaregions within the USA. Module:Location map/data/megaregion of United States is a location map definition used to overlay markers and labels on an equirectangular projection map of Megaregions of the United States. The markers are placed by latitude and longitude coordinates on the default map or a similar map image.
Enlargeable U.S. map with state and territory high points shown as red dots and low points as green squares except where low point is a shoreline. Enlargeable map of the 50 U.S. states by mean elevation. This list includes the topographic elevations of each of the 50 U.S. states, the District of Columbia, and the U.S. territories. [1]
Each state has its own set of reference parameters given in the standard. [8] The U.S. National Geodetic Survey's "State Plane Coordinate System of 1983" uses the Lambert conformal conic projection to define the grid-coordinate systems used in several states, primarily those that are elongated west to east such as Tennessee.
