I am working on a project where I need to navigate/reroute user just like Google Map Navigation.
I am successfully able to get different path locations where I am using distance calculation to get upcoming turns and path.
ISSUE :
(1) By time I am checking distance diff between current and upcoming two points but with no success to evaluate precise value. Need an Algo / Idea to make rerouting precise.
(2) U-Turn issue Some times the u-turn lat/long is far away with actual turn diameter. In these case my calculations gets disrupted.
I just need an idea on how Google maps provides such a precise value.
Any help !@!
Thanks.
