Abstract

Maps have traditionally been considered to be passive representations of geographic space, even after the introduction of digital techniques. The ability of the user to interact rapidly with the map on the screen has largely been limited to changes in classification and symbolism, as most, spatial data structures do not permit local real-time modification. However, with locallymodifiable “topology” the user’s cursor may be embedded in the map space, permitting the detection of neighbouring map objects and responding to potential collisions. This approach has been implemented using the Voronoi (Thiessen) spatial model. It has many advantages in interactive applications such as manual digitizing, fluid flow modelling and robotics. Map objects such as points or line segments may be added, deleted, interacted with or queried at any stage, and the method appears to have many potential applications.
