Network design in the context of GeoDesign problems is concerned with delineation of pathways through some spatial domain. Obvious examples in this realm include design of road and utility networks, which typically seek least-cost pathways that may involve both spatial and temporal considerations. The spatial computation for this class of design problem is almost always global. In addition to the more conventional notion of networks in terms of roads and utilities, in conservation biology, there is also the notion of reserve networks. To the extent that an analysis for reserve design explicitly treats connectivity of patches through connecting corridors, this is an apt characterization.
