使用Google Map API v3的国家边界 [英] Country boundries using Google Map API v3

问题描述

反正有，所以我可以使用Google map API获取多边形坐标值的国家边界。

Google地图V3：绘制德国州多边形？

FusionTables中的自然地球数据集具有可用的国家多边形。你可以根据自己的喜好来设计风格。

我用它来创建这个例子：
http://www.geocodezip.com/v3_FusionTablesLayer_worldmap_linkto.html

下面是一个使用KmlLayer的示例：

代码段：

  var kmlLayer = null; var map = null; function openIW（layerEvt）{if（layerEvt.row）{var content = layerEvt.row ['admin'] .value; } else if（layerEvt.featureData）{var content = layerEvt.featureData.name; } document.getElementById（'info'）。innerHTML =你点击了：< br> + content;} function initialize（）{var chicago = new google.maps.LatLng（36.4278，-15.9）; var myOptions = {zoom：0，center：chicago，mapTypeId：google.maps.MapTypeId.ROADMAP} map = new google.maps.Map（document.getElementById（map_canvas），myOptions）; google.maps.event.addListener（map，click，function（）{document.getElementById（'info'）。innerHTML =;}）; kmlLayer = new google.maps.KmlLayer（'http://www.geocodezip.com/geoxml3_test/world_countries_kml.xml'，{preserveViewport：true，suppressInfoWindows：true}）; kmlLayer.setMap（地图）; google.maps.event.addListener（kmlLayer，'click'，openIW）;} google.maps.event.addDomListener（window，'load'，initialize）;

Is there anyway so I can get boundries of countries in polygon coordinates value using Google map API.

See this similar question: Google Maps V3: Draw German State Polygons?

The Natural Earth Data Set in FusionTables has country polygons available in it. You can style them as you like.

I used it to create this example: http://www.geocodezip.com/v3_FusionTablesLayer_worldmap_linkto.html

Here is an example that uses a KmlLayer: http://www.geocodezip.com/v3_GoogleEx_layer-kml_world_countries_simple.html

code snippet:

var kmlLayer = null;
var map = null;

function openIW(layerEvt) {
  if (layerEvt.row) {
    var content = layerEvt.row['admin'].value;
  } else if (layerEvt.featureData) {
    var content = layerEvt.featureData.name;
  }
  document.getElementById('info').innerHTML = "you clicked on:<br>" + content;
}

function initialize() {
  var chicago = new google.maps.LatLng(36.4278, -15.9);
  var myOptions = {
    zoom: 0,
    center: chicago,
    mapTypeId: google.maps.MapTypeId.ROADMAP
  }

  map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);

  google.maps.event.addListener(map, "click", function() {
    document.getElementById('info').innerHTML = "";
  });


  kmlLayer = new google.maps.KmlLayer('http://www.geocodezip.com/geoxml3_test/world_countries_kml.xml', {
    preserveViewport: true,
    suppressInfoWindows: true
  });
  kmlLayer.setMap(map);

  google.maps.event.addListener(kmlLayer, 'click', openIW);
}
google.maps.event.addDomListener(window, 'load', initialize);

<script src="https://maps.googleapis.com/maps/api/js"></script>
<table>
  <tr>
    <td>
      <div id="map_canvas" style="height:200px; width:300px;"></div>
    </td>
    <td>
      <div id="info"></div>
    </td>
  </tr>
</table>
