According to the API ref, the map object should have a getProjection
method:
http://code.google.com/apis/maps/documentation/v3/reference.html#Map
While loading the map in this example should alert the x,y point, but instead throws the value as undefined. This is the below sample code called in onload.
function initialize() {
var mapOptions = {
zoom: 8,
center: new google.maps.LatLng(-34.397, 150.644),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
alert("projection:" + map.getProjection());
}

An MVCArray inherits from MVCObject so you can set or get its properties, bind some of them, be binded by other objects, etc. But also, it implements some extras. It implements several of the methods you could use in a native javascript array, like push , pop , forEach , etc, so several google.
Please go to your map and drag and drop your map to the position you wish. You can also zoom in your map a little bit with mouse wheel or zoom cotrols on the bottom right corner of the map. Please remember to save your map after any changes. Hope that helps.
It isn't available until the map is finished initializing. You have to wait on the "projection_changed" event before accessing it.
function initialize() {
var mapOptions = {
zoom: 8,
center: new google.maps.LatLng(-34.397, 150.644),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
google.maps.event.addListenerOnce(map,"projection_changed", function() {
alert("projection:"+map.getProjection());
});
}
