GoogleMaps Framework Reference

Page Summary

GMSMapPoint represents a point on the map, potentially a projected coordinate.
The x and y values range from -1 to 1, with (0, 0) at the map's center, and y increasing Northward, x increasing Eastward.
GMSProject() and GMSUnproject() are related functions for coordinate transformation.
The struct has two properties: x and y , both representing coordinates as Doubles.

  struct 
 GMSMapPoint 
 {}

A point on the map. May represent a projected coordinate.

x is in [-1, 1]. The axis direction is normal: y grows towards North, x grows towards East. (0, 0) is the center of the map.
