Implementing Google Map: how set auto zoom and center?

[ultim]

Hi,
I am currently implementing a google map into my site.

The pointers on the map is dynamically plotted.

Is there a way to set the zoom level and center depending the spread of the pointers?

Thanks

i believe not, although i havent done a huge amount of complex google maps stuff recently.

if you are plotting the points dynamiclly couldnt you work out the centre and rough required zoom level manually

Yea looks like i have to.

I was hoping there was something in the api i can use.

Thank you for replying!

You can set boundaries in googlemaps based on minimum and maximum longitude and latitude. Thats instead of using zoom and center.

Heres some example code from I site I did with a similar purpose:

http://www.mytripbook.com/trip/show/545/paying-respects-a-trip-to-belgium-and-france

var minLat=49.1810862;
var minLng=-1.5333333;
var maxLat=53.9833333;
var maxLng=3.2250023;
					
botLeft = new GLatLng(minLat, minLng);
topRight = new GLatLng(maxLat, maxLng);

bounds = new GLatLngBounds(botLeft, topRight);
map.setCenter(new GLatLng(((maxLat + minLat) / 2.0),((maxLng + minLng) / 2.0)),map.getBoundsZoomLevel(bounds));

You just need to use PHP to get the minimum/maximums from your array of points (assuming its coming out of a database)
