Calculating zoomToSpan() degrees based on min/max lat/lng to be in the mapView

Question

I have a cluster of items on an overlay in a mapView.
I know where the top/bottom/left/right most objects are.
I want to use the zoomToSpan() method to zoom onto that area.

What is the proper way to calculate the lat/lng degrees for this method ?

Answer 1

I found someone else posting a good solution to this problem here: http://www.anddev.org/zoom_and_span_on_a_cluster_of_points-t464.html

Good luck!

This question has been asked before, and there's an excellent answer, with code, here:

Answer 3

Wouldn't you want to just use something like this:

mapController.zoomToSpan(overlay.getLatSpanE6(), overlay.getLonSpanE6());
