谷歌地图地面覆盖缩放跳跃

Question

当我缩小然后放大图像叠加时，图像会移动到另一个地图副本。有什么建议？将Google地图的历史叠加示例中的叠加图像更改为覆盖全球的NOAA海洋表面温度。  https://developers.google.com/maps/documentation/javascript/examples/groundoverlay-simple

var historicalOverlay;

  function initMap() {
    var map = new google.maps.Map(document.getElementById('map'), {
      zoom: 3,
      center: {lat: 0, lng: 0}    
    });
    var imageBounds = {
        north: 79.995,
        south: -79.995,
        east: 179.005,
        west: -178.995
    };

    var overlayOpts ={opacity:1};
    historicalOverlay = new google.maps.GroundOverlay(
        'https://coastwatch.pfeg.noaa.gov/erddap/griddap/jplG1SST.transparentPng?SST[(2017-01-11T00:00:00Z)][(-79.995):(79.995)][(-178.995):(179.005)]&.draw=surface&.vars=longitude%7Clatitude%7CSST&.colorBar=LightRainbow%7C%7C%7C%7C%7C&.bgColor=0xffccccff',
        imageBounds, overlayOpts);        historicalOverlay.setMap(map);
  }
