If I'm not mistaken, Google Maps exports a route as a set of lat/lon coordinates (XML or the like). In your example, you would have something like this: 32.093114,34.781502 32.093419,34.781460 32.093765,34.780505 I'm not an expert, but Cartesian 2d logic should have some geometric function to check wheter a given point lies on a straight line. In your example, that function would need to be executed twice. Hope this helps, -- Bart -- You received this message because you are subscribed to the Google Groups "Google Maps API" group.
