SATELLITE POSITIONING AIDS MONTANA DOT INVENTORY

The Montana Department of Highways has started on a pilot project to use geographic positioning system/geographic information system (GPS/GIS) technology combined in a system caled GeoLink. The pilot project will establish the cost benefits and potentials as well as limitations of the sohpisticated technology. GeoLink incorporates a multi-purpose GIS, and Pathfinder AGPS receiver. GPS is a sophisticated navigation system that uses satelites to pinpoint any location on earth accurately and efficiently. The use of GPS to locate a position is described. The Montana built a well integrated GIS database that identified all aspects of the highways, including location, construction, signage, and structures relating to the highway within or affecting the right-of-way. Details of Montana's database, which consists of linear features and point features, are described. The database structure allows for uniform treatment of a wide variety of features, future expansion of the system, and extraction of feature classes into subsidiary databases for specific analysis. It is noted that the GPS/GIS gives the most practical solutions to highway maintenance inventory problems.
