ArcMap地理编码服务的发布与使用
目录
一、引言
地理编码是按照主要是地理位置描述与地理坐标的相互转换，主要包括地理编码与反地理编码。
地理编码指的是根据地名获取位置信息；
反地理编码指的是根据位置信息获取地名；
这个的使用我们要根据需求来做，其实这个功能类似mapservice中的空间查询与属性查询，自我感觉两者可以代替，猜测出这个服务的目的：数据量大的时候可能效率高，比较常用。
二、地理编码服务发布
1、创建locator
- toolbox中找到创建locator工具
- 按照提示添加参数，第一个locator样式，第二个shp数据，第三个查询字段，最后别忘了往下拉一下选择输出位置
- 下图是创建的locator
2、发布地理编码服务
- 右击locator，选择share as——geocode service
- 然后就跟普通map service发布类似了，直接掠过
- 最后参数设定，直接分析发布ok
- 发布之后的geocode service
三、地理编码服务在arcgis js中的使用
1、地理编码

var map = new Map("mapDiv");
var layer=new ArcGISDynamicMapServiceLayer("http://localhost:6080/arcgis/rest/services/WWJZ/build_info/MapServer");
map.addLayer(layer);
query("#btn").on("click",function(){
//获得教学楼的名称
var name=query(".nm")[0].value;
//创建地理编码对象
var locator = new Locator("http://localhost:6080/arcgis/rest/services/loc/quyu/GeocodeServer");
//注意这里的参数要和服务的参数对应
var address = { "Single Line Input": name};
//输出的空间参考
locator.outSpatialReference = map.spatialReference;
var options = {
address: address,
outFields: ["*"]
}
//执行方法
locator.addressToLocations(options,function(candidates){
//获得运行之后的信息
if (candidates.length > 0){
//拼接字符串
var htmls = "<table style='width: 100%'>";
htmls = htmls + "<tr bgcolor='#E0E0E0'><td>X 坐标</td><td>Y 坐标</td><td>得分</td></tr>";
array.forEach(candidates, function (candidate, index) {
if (index % 2 == 1) {
htmls = htmls + "<tr bgcolor='#E0E0E0'><td style='width: 60px'>" + candidate.location.x + "</td><td style='width: 60px'>" + candidate.location.y+ "</td><td>" + candidate.score + "</td></tr>";
} else {
htmls = htmls + "<tr><td style='width: 60px'>" + candidate.location.x + "</td><td style='width: 60px'>" + candidate.location.y+ "</td><td>" + candidate.score + "</td></tr>";
}
});
htmls = htmls + "</table>";
//将拼接的字符串显示在页面上
dom.byId("divShowResult").innerHTML = htmls;
}
},function(error){alert(error)}); });
});
</script>

<body class="tundra">

Name:<input class="nm" type="text">
<input id="btn" type="button" value="定位">
<div id="divShowResult"></div>
</body>
</html>
- 效果
2、反地理编码
这个反地理编码自己写的有点问题，老是说无效的参数直接找了网上一个，调用的在线的地图与服务，大家可以参考下

//

if (candidate.address) {
var graphic = new esri.Graphic(candidate.location, symbol, candidate.address, infoTemplate);
map.graphics.add(graphic);
map.infoWindow.setTitle(graphic.getTitle());
map.infoWindow.setContent(graphic.getContent());
var screenPnt = map.toScreen(candidate.location);
map.infoWindow.show(screenPnt,map.getInfoWindowAnchor(screenPnt));
}
});
dojo.connect(map, "onClick", function(evt) {
map.graphics.clear();
locator.locationToAddress(evt.mapPoint, 100);
});
}
dojo.addOnLoad(init);
</script>
</head>
<body class="tundra">
Left click on the map to get address.
<div id="map" style="width:1200px; height:600px; border:1px solid #000;"></div>
</body>
</html>
- 效果
