I need to create a MKCoordinateSpan that is about 500 meters.
How do I calculate the values to pass into the MKCoordinateSpan constructor?
Answers in any programming (Obj-C, .Net) language are fine.
Another alternative is to use MapKit's MKCoordinateRegionMakeWithDistance
function:
MKCoordinateRegion rgn = MKCoordinateRegionMakeWithDistance(
CLLocationCoordinate2DMake(someLatitude, someLongitude), 500, 500);
The MKCoordinateSpan
will be in rgn.span
.
