 How can i calculate the distance between two points on the bing map? 

Ist it possible to check whether a point is inside or outside of polygons?

Thank's a lot for your answer :)

Answer 1

There are a couple of ways to calculate distances. If you just want the straight line distance you can use the Haversine formula:

Alternatively if you want the driving distance you can use the Bing Maps REST services to calculate the route.

As for checking if a point is in a polygon you can do one of two things. The first is to follow the algorithm outlined here: http://msdn.microsoft.com/en-us/library/cc451895.aspx

The second is to use the SQL Spatial libraries in your application.

Thank's a lot for your help.

I'd like to use the Spatial Library of SQL Server. I found it in the Feature Pack of SQL Server. Is this the correct Library?

I didn't found a documentation or something else to use the library but i know the datatype's from SQL 2008 :)

Do you know a Documentation or anything else to use the Spatial Library assembly ?

Thanks for every answer

That's the correct library. Take a look at the documentation found here: http://msdn.microsoft.com/en-us/library/microsoft.sqlserver.types%28SQL.105%29.aspx
