I am looking to use network analysis to map journeys from one given point to another, I know it is possible to map the shortest journey and the most time and cost efficient journey using ArcMap but I wondered if it is possible to map the exact journey using network analysis? or can this only be done through plotting it with a polyline? Any suggestions as to how would be welcome!
- By exact journey I am referring to the journey the person has carried out, ideally from one named point to another. I have seen the most cost effective or shortest journeys mapped using ArcMap before but was wondering if it was possible to map a journey which had occurred which was not the most efficient?
- What information do you have off the journey? i.e., if it is a GPS trace then it can be mapped without the use of Network Analyst. If you have some way points then you can run a shortest path between these way points and display the results.
Jay Sandhu - If I had a GPS trace how would I map this? Do you use tracking analyst? Could this be done on top of a raster layer? If it was point data along the journey would I have to build a network first? Would all the details of the road networks around be needed?
Thanks
Can you clarify what you mean by an exact journey which is different from an shortest or most cost-effective journey? Thanks,
