Конечно, вы можете.Все, что вам нужно изменить в своем коде - это иметь 2 оверлея, объявленных как переменные, и 2 LatLngBounds
объектов.Здесь я создал второе наложение ниже того, которое вы используете в своем коде.
var overlay1;
// Declare a second overlay variable
var overlay2;
USGSOverlay.prototype = new google.maps.OverlayView();
function initMap() {
// Initialize the map and the custom overlay.
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 5,
center: {
lat: 66.323907,
lng: -150.109291
},
gestureHandling: 'cooperative',
zoomControl: false,
scrollwheel: false,
disableDoubleClickZoom: true,
streetViewControl: false,
panControl: false,
mapTypeControl: false,
mapTypeId: 'satellite'
});
var bounds1 = new google.maps.LatLngBounds(
new google.maps.LatLng(68.281819, -150.287132),
new google.maps.LatLng(68.400471, -150.005608));
// Declared a second bounds object
var bounds2 = new google.maps.LatLngBounds(
new google.maps.LatLng(65.281819, -150.287132),
new google.maps.LatLng(65.400471, -150.005608));

var srcImage = 'https://developers.google.com/maps/documentation/' +
'javascript/examples/full/images/talkeetna.png';
// The custom USGSOverlay object contains the USGS image,
// the bounds of the image, and a reference to the map.
overlay1 = new USGSOverlay(bounds1, srcImage, map);
// Create a second overlay

}

function USGSOverlay(bounds, image, map) {
// Initialize all properties.
this.bounds_ = bounds;
this.image_ = image;
this.map_ = map;
// Define a property to hold the image's div. We'll
// actually create this div upon receipt of the onAdd()
// method so we'll leave it null for now.
this.div_ = null;
// Explicitly call setMap on this overlay.
this.setMap(map);
}
/**
* onAdd is called when the map's panes are ready and the overlay has been
* added to the map.
*/
USGSOverlay.prototype.onAdd = function() {
var div = document.createElement('div');
div.style.borderStyle = 'none';
div.style.borderWidth = '0px';
div.style.position = 'absolute';
// Create the img element and attach it to the div.
var img = document.createElement('img');
img.src = this.image_;
img.style.width = '2000%';
img.style.height = '2000%';
img.style.position = 'absolute';
div.appendChild(img);
this.div_ = div;
// Add the element to the "overlayLayer" pane.
var panes = this.getPanes();
panes.overlayLayer.appendChild(div);
};
USGSOverlay.prototype.draw = function() {
// We use the south-west and north-east
// coordinates of the overlay to peg it to the correct position and size.
// To do this, we need to retrieve the projection from the overlay.
var overlayProjection = this.getProjection();
// Retrieve the south-west and north-east coordinates of this overlay
// in LatLngs and convert them to pixel coordinates.
// We'll use these coordinates to resize the div.
var sw = overlayProjection.fromLatLngToDivPixel(this.bounds_.getSouthWest());
var ne = overlayProjection.fromLatLngToDivPixel(this.bounds_.getNorthEast());
// Resize the image's div to fit the indicated dimensions.
var div = this.div_;
div.style.left = sw.x + 'px';
div.style.top = ne.y + 'px';
div.style.width = (ne.x - sw.x) + 'px';
div.style.height = (sw.y - ne.y) + 'px';
};
// The onRemove() method will be called automatically from the API if
// we ever set the overlay's map property to 'null'.
USGSOverlay.prototype.onRemove = function() {
this.div_.parentNode.removeChild(this.div_);
this.div_ = null;
};
initMap();
#map {
height: 200px;
}
<div id="map"></div>

Я переименовал ваши начальные переменные в overlay1
и bounds1
для ясности, но вы можете использовать любые имена переменных, какие захотите.
