If you examine the code you'll see that the client gets directions from Google and sends the obtained polyline to the server, which replies with the county data. What happens on the server side is that a spatial database server containing the geometry of the counties calculates the intersection between the polyline and the polygon of each county. So, you need a spatial database and the data for the counties or countries of interest. If you don't want to intall and administer a spatial database and you only have to deal with a handful of countries, you can probably achieve similar results with a plain text file holding the country polygons and a point-in-polygon function that checks each point in the route against each polygon. -- Marcelo - http://maps.forum.nu -- -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group.
