From line geometry to area topology

Abstract

Area objects are represented on a computer by geometric or locational information (which describe the course of their boundaries), topological information (which describe the areal units to which boundaries belong), and geographic or other information (which describe the objects which map onto these areal units).
Most available systems for spatial data processing require from the outset object-related information, in the form of left/right or on-line references or area-seeds, for extracting the area topology.
This paper introduces the Disassociative Area Model (DAM) and contrasts it with other existing descriptions of areal entities. The primitive region forms the basic spatial unit for object modelling and acts as the link between the geometric and geographic components. The derivation of spatial topology focuses on the boundary, which describes one extent of a primitive region. Geographic information may be input in a variety of ways and at any convenient stage using
pragmatic models derived from DAM.
