Abstract

USGS and the Census Bureau - TIGER Roads and The National Map
Track: Elections, Redistricting, and Census
Authors: David Cackowski

USGS and the US Census Bureau cooperate on the collection and maintenance of GIS transportation data, especially roads. The two agencies have aligned their production operations to leverage geospatial update operations and reduce duplication of effort. The result is a public domain road dataset with higher spatial accuracy, better alignment of roads with NAIP and other imagery, and improved partnership. Census TIGER is now the primary source for roads information in the USGS National Map.
