map.setHeading

[gullet]

Hi,

I'm wondering about the setHeading()-method and why I can't make it work. I recall having seen somwhere that setHeading is only available for maps where there is tilt-support, but I can't find that information either and if that is the case, I'm wondering why. According to the API Reference, it should support just a number as parameter, but it doesn't say anything about maps with tilt.

My task is to have my map shown in the same direction as the position from the geolocation supported browser gives me. Can I achieve that in any other way?

Thanks in advance.

I'm a bit disappointed having no answers on this. Is there no Google employee who can give a clarification on how to use the setHeading()-method and under what circumstances it is available.

Thanks in advance.

Perhaps because you didn't link to your map:

http://groups.google.com/group/google-maps-js-api-v3/browse_thread/thread/2b3f101fd509919e

The reference documentation for setHeading says:

Sets the compass heading for aerial imagery measured in degrees from cardinal direction North.

Aerial imagery appears only when the map has tilt set to 45.

See the documentation for details:

Mostly the group is used by fellow developers, Google employees do
look in from tme to time.

I know the documentation can be variable depending on language, but
the English version seems reasonably clear :

"Sets the compass heading for aerial imagery measured in degrees from
cardinal direction North."

So I guess the next question is, what is aerial imagery?
The documentation seems to provide the answer, along with an example
of using setHeading

Okay, fair enough. But let me rephrase the topic then:

I'm looking for the similar map functionality as in Places (for Android). When I tap my position it downloads the map with heading as cardinal north by default, but I can rotate the map and if I can rotate, I'm pretty sure that the heading is known to the map and settable (although I haven't looked into it).

Am I plumbing in the wrong API?

Thanks in advance.

Possibly. Regular Maps API doesn't do rotation. Maybe look at Google
Earth API. Regular Maps API doesn't do user location, though of
course you can interface to a number of user-location tools. If
you're trying to determine the direction the user is facing, those are
the tools to look at.
