Bing Maps Distance between Cordinatores

Question

Hello everyone,




    I am developing a small application that uses the latitude and longitude to calculate the distance between points.
I am using the following formula within a stored procedure and it works ok.
set @resultado =ACOS(SIN(RADIANS(@latitude_origem))*SIN(RADIANS (@latitude_destino))+COS(RADIANS(@latitude_origem))*COS(RADIANS(@latitude_destino))*COS(RADIANS(@dif_Longitude)))
            print  @resultado




With the formula above, the distance is calculated directly.




   I've been researching applications that allow to define routes and found thefollowing web services:
Application Using Bing MapsSOAP Services
http://msdn.microsoft.com/en-us/library/cc980922.aspx
My question is whether it is possible to obtain a route with the distance between twoor more coordinates, and if the route is drawn based on the shortest path.
Point LONGITUDE     LATITUDE
A      -8,750486    41,3559
B      -8,606915    41,15467
C      -8,631134    41,15847
D      -8,766627    41,40691
distances obtained results of the formula
AB=24
CD =31
If possible using the Bing MapsSOAP Services, 
is to confirm the results and see what the differences to the 
formula obtained using only the coordinates.
It is possible to obtain the distance between more than two points, 
for examplepassing through all points.


 I use this code to obtain de address with coordinator




string results = "";
string key = "”;
ReverseGeocodeRequest reverseGeocodeRequest = new ReverseGeocodeRequest();
reverseGeocodeRequest.Credentials = newGeoCodeService.Credentials();
reverseGeocodeRequest.Credentials.ApplicationId = key;
// Set the point to use to find a matching address
GeoCodeService.Locationpoint = newGeoCodeService.Location();


Thanks

yes given two points, you can use RouteService provided by Bing maps / Virtual Earth. The route service requires two coordinates and additional params that denoted whether you want Shortest time / distance with or without traffic info etc.

The result contains distance and legs. each leg containing info on the distance and time it will take etc in addition to other things.

Here's an example for Windows phone. There is another microsoft working sample that provides route info from
