Maptitude - http://research.umbc.edu/~roswell/maptitude.html

One mapping feature that I'd like to see added to Maptitude in the near future is the ability to draw lines of interaction between an origin (pt, line or area) and a destination (point, line or area) and weight the size of the line in proportion to the range in the data (i.e. like a scaled symbol).   ESRI refers to this style of map  in their Guide to GIS Analysis reference text (page 131) as a "spider diagram", although it doesn't appear as though the line weight can be scaled to the interaction data. (Perhaps ArcView or ArcInfo users may know).  I believe this mapping feature also exists in MapInfo.

The applications for this mapping feature are many, but to name a few:

  • commuter flows between counties,
  • origin-destination data from travel behavior surveys,
  • international or domestic inter-county migration flows between areas,
  • import-export flows between countries,
  • shopper origin surveys at retail locations, etc.
I believe this functionality already exists within Caliper's Transcad program because of its value for displaying spatial interaction...so it wouldn't seem to be a big development issue to add it to the Maptitude toolbox.

Anyone else like to see this feature added to Maptitude?
