Description

NCHRP Synthesis 301. This report provides information on the potential and the problems of integrating GPS data with data from GIS to provide departments of transportation with a powerful set of planning and programming tools. It addresses existing data standards and their applicability, procedures for processing and integrating spatial data, map matching algorithms and protocols, and recent developments in positioning, including cellular technology. The synthesis identifies a six-step method designed to help improve the quality of maps and reduce the severity of problems associated with GPS–GIS integration.NCHRP Synthesis 301.
