Hello,
I am fetching driving directions between 2 cities using Google
Directions XML API
http://code.google.com/apis/maps/documentation/directions/
It contains an encoded polyline for the entire route. Example
<overview_polyline> <points>a~l...@vlbbtc~@tse`vnapw{a...@~w\|
tn...@l{yd_fblh@</points>
<levels>BBBAAAAAABABABABBABAABB</levels>
</overview_polyline>
To render this encoded polyline using GPolyline function described
here
http://code.google.com/apis/maps/documentation/javascript/v2/overlays.html#Encoded_Polylines
we need to more parameters namely 'zoomfactor' and 'numlevels'. How
can I get these to parameters ?
Thanks,
karan
