About this dataset

Public geospatial data sets presented in formats commonly used by open-source tools. The greatest effort will be made to make data sets available in GeoJSON and SpatiaLite formats. Larger polygon data sets may also be made available as TopoJSON.

CD113 - 113th Congressional Districts, Census Bureau

milbase - US military bases, Bureau of Transportation Statistics

border_crossings - US border crossings, Bureau of Transportation Statistics
