SCHEMATIC VIEWS OF NETWORKS - WHY NOT HAVE IT ALL?
D Elroi · 1991
Network applications, such as routing analysis and dispatching require graphic representation of potentially complicated network maps to the user. The ability of the user to quickly and accurately pick out relationships among links and nodes, and to visually trace paths through the network, can be hampered by spaghetti-like networks. One method for simplifying and clarifying the visual displays of networks in a computerized environment, such as in network analysis and control software, is to create a schematic version of the network. To provide a schematic view at the expense of losing the accuracy of the detailed version, however, is a high price to pay. This paper introduces the concept of schematic maps, their benefits to GIS applications, the current state of affairs, and suggestions for future improvements.
