Calculate second point knowing the starting point and distance

Question

using a Latitude and Longitude value (Point A), I am trying to calculate another Point B, X meters away bearing 0 radians from point A. Then display the point B Latitude and

Answer 1

Here is an updated version using Swift:

let location = CLLocation(latitude: 41.88592 as CLLocationDegrees, longitude: -87.62788 as CLLocationDegrees)

let distanceInMeter : Int = 500
let directionInDegrees : Int = 135

let lat = location.coordinate.latitude
let long = location.coordinate.longitude

let radDirection : CGFloat = Double(directionInDegrees).degreesToRadians

let dx = Double(distanceInMeter) * cos(Double(radDirection)) 
let dy = Double(distanceInMeter) * sin(Double(radDirection))

let radLat : CGFloat = Double(lat).degreesToRadians

let deltaLongitude = dx/(111320 * Double(cos(radLat)))  
let deltaLatitude = dy/110540                   

let endLat = lat + deltaLatitude
let endLong = long + deltaLongitude

Using this extension:

extension Double {
    var degreesToRadians : CGFloat {
        return CGFloat(self) * CGFloat(M_PI) / 180.0
    }
}
