I'm trying to do a Nearest Neighbor analysis between points in 2 tables utilizing with distances set along specific polyline road files I have. I am attempting to determine the most cost effective way to undertake works for a local council. I'm using Mapinfo and can get nearest neighbor analysis but it is just straight line distance not using the roads.

It sounds like what you are really after is some routing software. Take a look at RouteFinder for MapInfo @ www.routeware.dk

Besides using some bespoke software I think the only other option is to attempt to write a routine yourself using MapBasic. Not the easiest task and probably not worth the effort given that there is already software available to do the job for you.

  • Thanks for your help, I've got hold of routeware now, what would be the best tool to use in this case?

  • You might want to look at the travelling salesman functionality, though I've never used RouteFinder personally so am probably not the best person to advise on it's use. I would have a read through the documentation online @ routeware.dk/routefinder/help/index.html to get an understanding of what it can do and how to do it.
