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.

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

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

);

Please edit this wiki (or update your question) once you have the answer. Thanks
