Resize google map to show all points
Mon, 2008-03-10 20:45 — chris
I needed to get a google map to center and scale based on the added points.
I found a tutorial here: http://econym.googlepages.com/basic14.htm
This gave me exactly what I needed.
In short, given a GMap2 object called map and a map of locations (name -> object with lat and lng properties):
map.setCenter(new GLatLng(0,0),0);var bounds = new GLatLngBounds();
for (name in locs) { var loc = locs[name]; var latlng = new GLatLng(loc.lat, loc.lng); var marker = new GMarker(latlng);
bounds.extend(latlng);
map.addOverlay(marker);
}
map.setZoom(map.getBoundsZoomLevel(bounds));
map.setCenter(bounds.getCenter());
