I have the task to find out what is necessary to build a routing application using ArcGIS Server. I am not a GIS beginner, but have had no experience with ArcGIS Server. As this project is at the "ideas" stage, I would like to start my research here by asking if anyone could give me some guidelines regarding what would be a sensible way to start a routing project using primarily (but not necessarily limited to) ESRI Software. Which extentions? What type/quality of data? Planning tips? Which organisations etc etc?
In terms of type of data, you can specify your origin and destination either as text strings (e.g. "Chicago, IL" or "Darwin, NSW, Australia") or as LatLng values. And the routing result could be displayed as a polyline drawing the route on a map. That means a table with list of pairs of A and B information can be used as input data.
