MFworks Tutorial – 03 Incremental Linkage

This operation infers the lineal characteristic of raster cells, by equating consecutive locations with a set of straight lines between them (Figure 1-3). Based on its relations with neighboring cells that have the same attribute value, each cell is given a linkage value indicating how it is linked to other cells.

Incremental Linkage, cell value infers the linear structure it represents.

By assigning a value to each cell equivalent to the linear feature it represents it is possible to create a network similar to a road network. The smaller the cell resolution, the better the real-world road network will be approximated by this procedure.

MFworks Tutorial – 09 Map Layers Needed

Map layers needed: A network, a cost surface, origin and destination point,

network.mfm

costoftravel.mfm

startstop.mfm

(image missing)

The network is a replica of the Brown’s Pond study area used by Tomlin. The cost surface are fictitious values, 1-4, indicating impedance. Origin and destination were derived by assigning the values 999 and 998 respectively to points on the network map (startstop.mfm) and then extracting each point using Recode.
