Question

I have two maps on a page, one is a map of the world, and the other is a closeup of the current place they picked on the map of the world. I would like to set different zoom min/max levels for each map but:

G_NORMAL_MAP.getMinimumResolution = function(){return 11};

Seems to set the same min/max for both maps, I can’t set them to different levels.

I think the problem is probably elsewhere in your code – I’m not sure exactly how you’re using that function.

Here is a method that will work. You can re-write it to have less duplication.

map1 = new GMap2(document.getElementById("map1"));
map1.addControl(new GLargeMapControl3D());
map1.addControl(new GMenuMapTypeControl());

var mt = map1.getMapTypes();
// Overwrite the getMinimumResolution() and getMaximumResolution() methods
for (var i=0; i<mt.length; i++) {
    mt[i].getMinimumResolution = function() {return 7;}
    mt[i].getMaximumResolution = function() {return 11;}
}
map1.setCenter(new GLatLng(40,-100), 8);    


map2 = new GMap2(document.getElementById("map2"));
map2.addControl(new GLargeMapControl3D());
map2.addControl(new GMenuMapTypeControl());

var mt = map2.getMapTypes();
// Overwrite the getMinimumResolution() and getMaximumResolution() methods
for (var i=0; i<mt.length; i++) {
    mt[i].getMinimumResolution = function() {return 2;}
    mt[i].getMaximumResolution = function() {return 6;}
}

map2.setCenter(new GLatLng(40,-100), 4);
