title: Calculate zoom level on google maps control in C#
body: <p>I'm using <a href="http://googlemap.codeplex.com/releases/view/52051" rel="nofollow">GoogleMap Control</a> have a collection of markers with Geo locations.  I can calculate the min and max lat longs and find the center point on where to center the map but I also need to calculate the zoom level programmatically. Does anyone how to do this?</p>
