Maximum Lat and Long bounds for the world - Google Maps API LatLngBounds()

Question

The Google Maps terrain view by default has unlimited panning of the map tile. You can use LatLngBounds() to limit this, but what are the maximum and minimum coordinates I should use to set the viewport as just the earth and not outside the map region?

Coordinates for North America:

var strictBounds = new google.maps.LatLngBounds(
    new google.maps.LatLng(28.70, -127.50), 
    new google.maps.LatLng(48.85, -55.90)
);

I've tried (+90, -180)(-90,180) to no luck.

Answer 1

The links provided by @Marcelo & @Doc are good for understanding the derivation of the Lat Lng:

• https://groups.google.com/forum/?hl=en&fromgroups=#!msg/google-maps-api/oJkyualxzyY/pNv1SE7qpBoJ
• https://en.wikipedia.org/wiki/Mercator_projection#Mathematics_of_the_Mercator_projection

But if you just want an answer for the maximum bounds for Google Maps:

Latitude: -85 to +85 (actually -85.05115 for some reason)

Longitude: -180 to +180

Try it for yourself on the Google Maps:

• https://maps.google.com/?q=85,180
• https://maps.google.com/?q=-85.05115,180

(You may need to Zoom Out. See how the pin is at the "edge" of the world - these are the limits)

So in your code Try:

var strictBounds = new google.maps.LatLngBounds(
    new google.maps.LatLng(85, -180),           // top left corner of map
    new google.maps.LatLng(-85, 180)            // bottom right corner
);
