Software For Spatial Analysis On A Network

the shortest-path distance. (2)The Network Space We suppose that the real world is represented by a network space formed by connected line segments, and that every geographical objects are assigned on the network (Figure 1). For instance, a store is assigned on a point on the network in terms of its access point, i.e. the gate or the entrance of the store. A house of a consumer is also assigned to a point on the network in the same manner. Thus the distributions of stores and consumers are represented by the distributions of points on the network. A line segment of the network may have attribute values, such as the width of a street, and a traffic volume.
