Question

I’m trying to embed Google’s directions into an iphone app There doesn’t seem to be a straightforward way to pull turn by turn data (specifically JSON data) other than adding a UIWebView.

I was wondering if it’s a terms of service violation problem or is it something that just hasn’t been implemented yet for the iphone.

I’ve seen Google’s directions data imported and styled in flash but I haven’t seen anything relating to maps other than linking out to the Google maps iphone app.

Answer 1

From the Google Maps Terms of Use

2: Restrictions on Use. Unless you have received prior written
authorization from Google (or, as
applicable, from the provider of
particular Content), you must not:

(a)
access or use the Products or any
Content through any technology or
means other than those provided in the
Products, or through other explicitly
authorized means Google may designate
(such as through the Google
Maps/Google Earth APIs);

(b) copy,
translate, modify, or make derivative
works of the Content or any part
thereof;

(c) redistribute, sublicense,
rent, publish, sell, assign, lease,
market, transfer, or otherwise make
the Products or Content available to
third parties;

(d) reverse engineer,
decompile or otherwise attempt to
extract the source code of the Service
or any part thereof, unless this is
expressly permitted or required by
applicable law;

(e) use the Products
in a manner that gives you or any
other person access to mass downloads
or bulk feeds of any Content,
including but not limited to numerical
latitude or longitude coordinates,
imagery, and visible map data;

(f)
delete, obscure, or in any manner
alter any warning, notice (including
but not limited to any copyright or
other proprietary rights notice), or

the Content; or

(g) use the Service or Content with any products, systems, or applications
for or in connection with (i) real

including but not limited to
turn-by-turn route guidance that is
synchronized to the position of a
user’s sensor-enabled device; or (ii)
any systems or functions for automatic
or autonomous control of vehicle
behavior.

I don’t know the specifics of your app, but I’m thinking it’s easy to run into issues with clause 2.g.
