For a project i need to save the zoom of a google map field.
So i do this :

In core/fields/google-map.php
I added in create_field :

$field['value'] = wp_parse_args($field['value'], array(
	'address'	=> '',
	'lat'		=> '',
	'lng'		=> '',
	'zoom'		=> ''
	));

and

$keys = array( 
	'data-id'	=> 'id', 
	'data-lat'	=> 'center_lat',
	'data-lng'	=> 'center_lng',
	'data-zoom'	=> 'zoom'
	);

And in js/input.js

// value exists?
	var lat = this.$el.find('.input-lat').val(),
	    lng = this.$el.find('.input-lng').val(),
	    zoom = parseInt(this.$el.find('.input-zoom').val());

if( zoom )
{
    this.map.setZoom(zoom);
}

and

google.maps.event.addListener( this.map, 'zoom_changed', function( e ) {
	// reference
	var $el = this.$el;

	var zoom = this.getZoom();

	// update input
	$el.find('.input-zoom').val( zoom ).trigger('change');
	});

And it works.
Hope this help.
