Fit coords to Google Map V3 LatLng

Question

I'm trying to fit the x & y coords I get from a game to a custom image map with Google Maps V3.

The coords I get from the game are both between 0 and 15360. In the custom map the NorthEast corner LatLng is (95, 180) and the SouthWest corner LatLng is (-82.5, -180).

So, my function to transform from game coords to Google Map LatLng is:

function getLatLngFromCoords(x, y) {
    x = parseFloat(x.replace(",", "."));
    y = parseFloat(y.replace(",", "."));
    var lng = x / (15360 / 360) - 180;
    var lat = y / (15360 / 177.5) - 95;
    return new google.maps.LatLng(lat, lng);
}

but it doesn't fit right to the positions.

I got the NorthEast and SouthWest LatLng making Markers and adjusting them to see when they was in the corner of my image map.

Wherever, when I get the bounds of the map with map.getBounds()

I see this:

    map.getBounds().getNorthEast(); // nb: 89.76247963221984, ob: 180
    map.getBounds().getSouthWest(); // nb: -87.43214656352167, ob: -180

Answer 1

You are using wrong latitude value for NorthEast corner. Your values are LatLng (95, 180). Maximum value for latitude is 90, so this is most probably cutoff to (90, 180).

For example, using

new google.maps.LatLng(95, 180);

I got object:

Q {nb: 90, ob: 180, toString: function, ...
