The Centerline Data Distribution System (CDDS) is a tool for sharing GIS based local and state road datasets between public, nonprofit, and governmental organizations. The users of this site are composed of local, regional, state, and federal government agencies, and affiliated nonprofit organizations. This site was created to serve as a repository and secure distribution center for street centerline files and statewide road datasets. The goal of the site is to reduce the time and effort local data providers and staff of local, regional, state, and federal governments spend distributing and collecting road data.
