Deck 8: Getting There Quicker With Geospatial Technology

Question 1

What are two ways of finding a shortest path between stops in a GIS?

Answer 1

Two methods are; 1)finding the shortest path between a set of stops in order.For instance,three stops may need to be visited in a specific order from home-stop 1 first,stop 2 second,and stop 3 third.Of all possible paths,the GIS would determine the shortest route from home to stop 1,then from stop 1 to 2,then from 2 to 3.2)Finding a shortest path be re-ordering the stops.For instance,it may be overall shorter to travel from home to stop 3,then to stop 1,then to stop 2.
