A graph-based model for the representation of land spaces

This paper introduces a graph-based and structural model for the representation of land spaces. We develop a spatial model that integrates three complementary abstractions (i.e., parcels, buildings, roads) that provide a spatial and structural representation. The modeling approach retains different categories of topological relations between parcels, buildings and roads, thus generating different graphs whose properties are evaluated and computed using graph-based operators. The union of these graphs generates a connected spatial graph where buildings are closely associated to parcels and the road network, then providing many opportunities for structural analysis.
