Once this integrated network has been developed, points of interest (POIs), including parks, schools, and hospitals, can be added to the network. These POIs are associated with one or more nodes on the network on the basis of either locations. If they are point locations, like hospitals and schools, a single point is used. If they are large polygons, like parks, then the shape is disaggregated into a representative “cloud” of points which are assigned to the network, each representing a subset of the total park (in terms of, for example, acreage).
