Automated schematic map production using simulated annealing and gradient descent approaches

Generating schematic maps are an effective means of generalization of large scale network datasets. The aim is to enhance visualization at line networks and also make them user friendly for interpretation. The basic steps for generating schematic maps are to eliminate all features and networks (or portions of networks) that are not functionally relevant to the network system chosen for mapping. All geometric invariants of the network's structure are relaxed except topological accuracy. Routes and junctions are represented diagrammatically.
