MFworks Tutorial – 09 Map Layers Needed

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

network.mfm

costoftravel.mfm

startstop.mfm

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.
