The Department of Transportation also has a need to become familiar with Global Positioning System(GPS) technology. GPS technology is maturing, and promises to economically solve many problems associated with determining locations. One problem is referencing data over time. In a recent report "Historical Database Feasibility Study" it was emphasized that a (x,y,z) coordinate system is necessary to reference data over time, in other words, for historical data bases. Our current data base system consists of an Intergraph (CAD) system and a Roadway Environment System (RES).
Many DOT activities gather vast quantities of data or highway attributes rapidly. GPS provides an opportunity to provide very accurate location data along with other data attributes. Some of the activities that may benefit from GPS are engineering surveying, secondary roads, road profiler, non-state trunk road inventory, mapping and video logger. A pilot GPS study is needed to give the Department experience in GPS equipment and utilization of the data.
