# Coordinates

Coordinates.cs

Coordinates class is widely used inside by GO Map to wrap GPS coordinates and converting them to and from Vector3 coordinates.
It offers a series of useful methods to work with geographic data, use it if you want to add any Location logic to your app.

This is how you convert a lat lon to vector3 and place objects on map!

Coordinates coordinates = new Coordinates (lat, lng,0);
gameobject.transform.localPosition = coordinates.convertCoordinateToVector(0);

And vice versa, this is how you get a GPS coordinates from a Vector3

Coordinates currentLocation = Coordinates.convertVectorToCoordinates (gameobject.transform.position);

Also from a Coordinate you can always get the center coordinate of the tile it’s contained, given the current zoomlevel:
Coordinates tileCenter = someCoordinate.tileCenter(zoomLevel);

And the tile coordinates (column, row) as well:
Vector2 tileCoords = someCoordinate.tileCoordinates(zoomLevel);

There are many useful methods in the coordinates class, basically anything you need for your GPS based project:
