Question

我使用Google's documentation中的示例当我添加自己的照片时，这很有效。

但是当我改变坐标时，照片就不再显示了。

我通过在Google地球中添加图像（图像叠加）来获取坐标。

我不明白我做错了什么。

代码：

<!DOCTYPE html>
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no">
<meta charset="utf-8">
<title>Ground Overlays</title>
<style>
  html, body, #map-canvas {
        height: 100%;
        margin: 0px;
        padding: 0px
  }
</style>
    <script src="https://maps.googleapis.com/maps/api/js?v=3.exp&signed_in=true"></script>
    <script>
// This example uses a GroundOverlay to place an image on the map
// showing an antique map of Newark, NJ.

var historicalOverlay;

function initialize() {

  var newark = new google.maps.LatLng(58.8110, 8.526);
  var imageBounds = new google.maps.LatLngBounds(
      new google.maps.LatLng(58.989835, 9.050201),
      new google.maps.LatLng(58.612911, 7.917444));

  var mapOptions = {
    zoom: 10,
    center: newark
  };

  var map = new google.maps.Map(document.getElementById('map-canvas'),
      mapOptions);

  historicalOverlay = new google.maps.GroundOverlay(
      'http://xxxxxxxxx/test/images/map/kart.JPG',
      imageBounds);
  historicalOverlay.setMap(map);
}

google.maps.event.addDomListener(window, 'load', initialize);

    </script>
  </head>
  <body>
    <div id="map-canvas"></div>
  </body>
</html>

Answer 1

LatLngBounds的预期参数是

SouthWest
东北地区

...但您提供了：

东北地区
西南

切换参数，您就会看到图像

// This example uses a GroundOverlay to place an image on the map
// showing an antique map of Newark, NJ.

var historicalOverlay;

function initialize() {

  var newark = new google.maps.LatLng(58.8110, 8.526);
  var imageBounds = new google.maps.LatLngBounds(
      new google.maps.LatLng(58.612911, 7.917444),
      new google.maps.LatLng(58.989835, 9.050201)
  );

  var mapOptions = {
    zoom: 10,
    center: newark
  };

  var map = new google.maps.Map(document.getElementById('map-canvas'),
      mapOptions);
map.fitBounds(imageBounds);
  historicalOverlay = new google.maps.GroundOverlay(
      'http://i.stack.imgur.com/mA4e2.jpg?s=256&g=1',
      imageBounds);
  historicalOverlay.setMap(map);
}

google.maps.event.addDomListener(window, 'load', initialize);

＆＃13;

html, body, #map-canvas {
        height: 100%;
        margin: 0px;
        padding: 0px
      }

<script src="http://maps.googleapis.com/maps/api/js?v=3"></script>
<div id="map-canvas"></div>
