I'm not sure. There are definitely friction coefficient differences between the two surfaces and I'd be willing to bet that one would be more efficient to travel across than the other. Perhaps routing engines could use this information
to provide an even better, more efficient route. Of course, that is just an idea.<br></div><div> <br></div><div> R,<br></div><div> Eric <br></div><div> <br></div><div> _______________________________________________<br></div><div> Talk-us mailing list<br></div><div> <a href="mailto:Talk-us@openstreetmap.org" target="_blank">Talk-us@openstreetmap.org</a><br></div><div> <a href="https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.openstreetmap.org%2Flistinfo%2Ftalk-us&data=05%7C01%7CDavid.Salmon%40tomtom.com%7Ce6955d37d4ff497ffd3208daff068cd4%7C374f80267b544a3ab87d328fa26ec10d%7C0%7C0%7C638102700981225737%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=vrY2636cAdMhOeSpld9Lb6PcjhgZowdry3bR8Xd6z40%3D&reserved=0" target="_blank">https://lists.openstreetmap.org/listinfo/talk-us</a><br></div><p></p></blockquote></div></div></div><div>_______________________________________________<br></div><div>Talk-us mailing list<br></div><div><a href="mailto:Talk-us@openstreetmap.org">Talk-us@openstreetmap.org</a><br></div><div><a href="https://lists.openstreetmap.org/listinfo/talk-us">https://lists.openstreetmap.org/listinfo/talk-us</a><br></div><div><br></div></blockquote><div><br></div></body></html>
