It's wrong. X - longitude, Y - latitude.

Screen space is not equal World space.
No matter what you are using GUI, uGUI, Tileset.
It is always wrong.
For tileset use GetWorldPosition.
For the other controls: you need to convert screen position to world position.

I am trying this with the tile example, trying to put in a gameobject around Brisbane.

GameObject newEntity = null;
newEntity = GameObject.Instantiate(pedTemplate);
var unityPosition = OnlineMapsControlBase.instance.GetScreenPosition(new Vector2(-27.52188f, 153.0187f));
newEntity.transform.position = unityPosition;

and

newEntity.transform.position = new Vector3(unityPosition.x, 0, unityPosition.y);

Its not putting the object in the correct place.

bool OnlineMapsTileSetControl.GetCoordsByWorldPosition (out double lng, out double lat, Vector3 position)

Online Maps v2.3 beta (available through the built-in update):
void OnlineMapsControlBase.GetPosition(double lng, double lat, out double px, out double py)
Vector2 OnlineMapsControlBase.GetScreenPosition(double lng, double lat)
Vector3 OnlineMapsTileSetControl.GetWorldPosition(double lng, double lat)
Vector3 OnlineMapsTileSetControl.GetWorldPositionWithElevation(double lng, double lat, double tlx, double tly, double brx, double bry)

I don't see the double implementation for these methods.

Yes, almost every method (where necessary) has an overload double precision.

Consider: https://en.wikipedia.org/wiki/Decimal_degrees

Is there a double implementation? I would like centimeter level accuracy.

How can I go from Unity coordinates to real world coordinates and vice versa?

For example I want to create 1000 gameobjects and I need them to be at Lat Lng 51,-1.
