polyline encoding samples #129

Open kevinkreiser opened 7 years ago

kevinkreiser commented 7 years ago

we need a corollary to: https://github.com/valhalla/valhalla-docs/blob/master/decoding.md in which we share sample code to generate an encoded polyline that valhalla will accept. there are off the shelf ones but they may not allow for 6 digits of precision or they may swap lat and lon. its best to just show the example ourselves:

for starters heres the c++11 version: https://github.com/valhalla/midgard/blob/6a74643fed445588a2997d37132370bf3e456991/valhalla/midgard/encoded.h#L81-L119

we can do python and js as well.
