I have a database full of JSON encoded directions results that I got
by using the v2 api. I would like to migrate my application to v3, but
it appears the format of directions responses has changed
considerably. Has anyone tried to convert this data? If not, could
anyone point me in the right direction? I'm not sure how to convert
the polyline data, which is all I really care about. Here is an
example v2 directions response that I have in case it helps:
{"copyrightsHtml" : "Map data ©2010 Google
","summaryHtml":"472 ft","Distance":{"meters":
144,"html":"144 m"},"Duration":{"seconds":6,"html":"0
minutes"},"Routes":[{"Distance":{"meters":
144,"html":"144 m"},"Duration":{"seconds":6,"html":"0
minutes"},"Steps":[{"descriptionHtml":"Head \u003cb\u003esouth\u003c/b
