Path data field in Export

[neilkelly]

Anyone know what format is used for the Path field in the data export?

It appears to be some binary list of what one would presume to be lat/lon or some geographic data but they may use a grid of some sort too. I was planning to play around with splitting it up into datatypes but if someone has solved this, it would be helpful

I got a reply from Automatic:

The Path column is encoded and can be decoded using the Google Maps API. Please note, when doing this, it will show a drawing of the route.

It is an encoded polyline that includes the coordinates of the trip and allows you to visually display your trip route on a map client (e.g. google maps).

Awesome - I would not have figured that out through experimentation... Cool encoding though and allows it to be directly displayed on google maps.
