ABSTRACT
This chapter provides advice on how to represent Geographic Information as Linked Data. It examines identity, classification, geometry, topology, and mereology through examples based on the imaginary island state of the Merea. When considering identity, Merea Maps needs to think about what it is interested in identifying with Uniform Resource Identifiers (URIs) and then think about how to construct these URIs. A geometrical description of a geographic object is obviously important, but in Linked Data terms, topology and mereology are probably more important. Topology can be used to express the spatial properties between topographic features, for example, whether two buildings are next to each other, and to express the connectivity within a network such as a road system. Network topology is the expression of properties that exist between elements of a network of some form or other. As Linked Data is structurally a graph, it is able to naturally represent network topology.
