Find driving distance   

I would like to find the driving distances between 2 addresses.  I can get 
the geocode (lat/long) from the addresses using Find Service.  I don't need 
the actual route between the 2 addresses but I do need the shortest distance 
between them.  Is there a call for this.
Thanks,
Marc

Marc,

There has to be latitude/longitude pair in order to calculate a distance 
between two points.  What other information do you have about these 
locations?  If you have address information, you can reverse geocode it into 
latitude/longitude using the FindServiceSoap.GetLocationInfo method:

Hope that helps,

Hi Marc

You can find the distance between two lat/longs by getting the route. I know 
you stated that you don't need the actual route, and you don't have to use 
it, but it is the route that will determine the driving distance between two 
points. 

To do this, you call the CalculateSimpleRoute method off of the 
RouteServiceSoap web service, like this:

LatLong[] routePoints= new LatLong[2];
routePoints[0] = new LatLong();
routePoints[0].Latitude = 40;
routePoints[0].Longitude = -120;
routePoints[1] = new LatLong();
routePoints[1].Latitude = 41;
routePoints[1].Longitude = -121;

Route route = routeService.CalculateSimpleRoute(routePoints, "MapPoint.NA", 
SegmentPreference.Shortest);

The parameter called routePoints is just a collection of lat/longs (starting 
and ending location). "MapPoint.NA" defines the data source, and 
SegmentPreference.Shortest can be set to Shortest, Quickest, or 
PreferredRoads. 

Once you have your route, the distance is found off of the Itinerary object, 
which is a property of the route object, like this:

string distance = route.Itinerary.Distance.ToString();
