MFworks Tutorial – 02 Network Modelling

The key to producing a successful network model is in understanding the relationship between the characteristics of physical network systems and the representation of those characteristics by the elements of the network model. The efficacy and validity of the network depends on how precisely the network can be modeled to match the real world network it represents. A network can be explicitly modeled in vector GIS, but can only be approximated by a raster GIS like MFworks.

Network representation in vector GIS: Nodes (numbers) and arcs (letters)

A network in vector GIS takes the form of edges (or arcs) connecting pairs of nodes (or vertices). Nodes can be junctions and edges can be segments of a road.
