bearing

I got the below code from @DanS at this link how-to-display-a-map-still-image-file-with-a-moving-current-location onCurrentPosition(Location current){ double hypotenuse = upperLeft.distanceTo(current); double bearing = upperLeft.bearingTo(current); double currentDistanceX = Math.cos(bearing) * hypotenuse; // "percentage to mark the position" double currentPixelX = (currentDistanceX / upperLeft.distanceTo(lowerRight) * Math.cos(upperLeft.bearingTo(lowerRight))) * mapWidth; moveIndicatorX(currentPixelX); } Here are the values: current: 41.850033,-87.65005229999997 upperLeft: 41.866514127810355,

I want to rotate GMap by changing the bearing angle value, so the camera rotates around the center point (360-Degree one full round ). When we change the bearing, there is a easing effect at camera start and end points. How can I control/change that in order to make the rotation smooth when change Bearing values (in order to rotate map in 360 Degree, smooth animation)? Required this for all languages as it appears the easing effect is different in different language libraries. e.g. Swift, Android, PHP, JS, Node.js, React. Swift Example (running OK in Linear Animation): Note that initially the

I implemented the "bearing" formula from http://www.movable-type.co.uk/scripts/latlong.html . But it seems highly inaccurate - I suspect some mistakes in my implementation. Could you help me with finding it? My code is below: protected static double bearing(double lat1, double lon1, double lat2, double lon2){ double longDiff= lon2-lon1; double y = Math.sin(longDiff)*Math.cos(lat2); double x = Math.cos(lat1)*Math.sin(lat2)-Math.sin(lat1)*Math.cos(lat2)*Math.cos(longDiff); return Math.toDegrees((Math.atan2(y, x))+360)%360; } You just have your parentheses () in the wrong place. You are adding

I want to rotate marker as per bearing or sensor value received from Accelerometer to show the user where actually he is moving. I have set marker icon and flat value to true but its not working as required. mCurrentLocationMarker.position(new LatLng( LocationUtils.sLatitude, LocationUtils.sLongitude)); mCurrentLocationMarker.icon(icon); mCurrentLocationMarker.flat(true); mCurrentLocationMarker.rotation(LocationUtils.sBearing); if (currentMarker != null) { currentMarker.setPosition(new LatLng( LocationUtils.sLatitude, LocationUtils.sLongitude)); } else { currentMarker = mGoogleMap .addMarker

I use that Google Maps component MapView in an Android application. I can use the GPS location to show my location with a dot. But I would like to show an arrow instead, that points out the driving direction (bearing). I think that I can use the bearing value to get the angle of the arrow. How can I do that? pheelicks Assuming you've got the Location then obtain the bearing by doing: float myBearing = location.getBearing(); To implement the overlay you'll be using ItemizedOverlay and OverlayItem . You'll need to subclass OverlayItem to add the functionality to rotate the Drawable. Something
