The google API covers how to decode these programatically, or you can do it manually here (though it will be slow for thousands of points)<br />http://facstaff.unca.edu/mcmcclur/googlemaps/encodepolyline/decode.html<br /><br />The response has a high level overview_polyline -- which has a few hundred points in the case of the I-5. If you want more detail, each individual leg has much finer detail level. For the I-5, this was well over 8000 points. <br /><br />Doing this manually (copy/paste the encoded polylines into the decoder from each step)... it took a few minutes to get a few thousand points. Or one could implement a simple page to specify a route, then call google api, and grab all the resulting details and stuff into lat/lon, or whatever format you want...bumblebeebunnynoreply@blogger.comtag:blogger.com,1999:blog-31054369.post-9849684422551634532011-11-30T19:03:57.590-08:002011-11-30T19:03:57.590-08:00We can volunteer for I-68 and/or I-70. However we have never done anything like this. Is it that you plot the lat/long every 5 miles along the route? How do you present the results? on a spreadsheet?Girlguideshttp://www.blogger.com/profile/00990158118979248325noreply@blogger.comtag:blogger.com,1999:blog-31054369.post-75161230553760503842011-11-30T05:01:33.073-08:002011-11-30T05:01:33.073-08:00I&#39;ll volunteer for US-40, The National Road.
