Note also that with careful parsing of the coordinates of the bounding box, it is possible to calculate an approximation of the user's altitude. Several Keyhole users have asked for the ability to simulate the LOD-type display of data (i.e. dynamically displaying more data as the user's viewpoint gets closer to the ground). This is now possible.





Edit: According to this thread this is due in next release, horray!

Theres no way to get an idea of the viewers direction (when at low angles), am I correct in this?

The reason I'm asking is that I have some datasets (see this thread) that have far to many points to download for wide views.

Therefore what I've done is just display 150 random points within the view, this works quite well when the viewpoint is directly overhead. But when going to lower angles, a large proportion of the viewable area is away in the distance. Therefore out of my random markers many are actully quite a distance from the user.

Ideally what I would like is to be able to display more points in the foreground, and less in the background (but maybe still a few to show there are some more 'out there')

I can't see how this is possible with just the BBOX, any other ideas?

Thanks Barry
