Maptitude - http://research.umbc.edu/~roswell/maptitude.html Peter: Thanks for your response and explanation. So are you suggesting that Maptitude users go out and invest $9,995 in Transcad to generate a map to view it with a $395 program they already have? Your response is also silent on the existence of this functionality within GIS+. Is this a compatible solution to achieve the plotting of desire lines, be they one-way or bi-directional?
