AN OBJECTIVE VIEW OF SEGMENTATION
D. Michael Glenn · 1992
The interest in GIS has been particularly intense in the transportation industry. By its very nature, a great deal of the information managed by this industry is geographic. The management of routes and rails, the movement of goods from place to place, the response to the ever changing public demands for new and efficient transportation methods are problems that require complex integration of a wide variety of kinds of information. All of this information must be tightly integrated in a geographic sense to obtain accurate and reasonable solutions. There has been, however, a major technical problem to the use of current GIS in the transportation industry: information about a route, rail, utility line or any other linear network is not constant for the length of the route. To overcome this problem, the GIS must allow collection of distributed attribute information so that each attribute may have its own independent linear distribution.
