综述：本节讲述的是用Arcgis for js加载天地图的切片资源。

天地图的切片地图可以通过esri.layers.TiledMapServiceLayer来加载，在此将之进行了一定的封装，如下：

1、切片线划图——TDTLayer.js

[javascript] view plaincopy print?

define(["dojo/_base/declare",
"esri/layers/tiled"],
function (declare) {
return declare(esri.layers.TiledMapServiceLayer, {
constructor: function () {
this.spatialReference = new esri.SpatialReference({ wkid: 4326 });
this.initialExtent = (this.fullExtent = new esri.geometry.Extent(-180.0, -90.0, 180.0, 90.0, this.spatialReference));
this.tileInfo = new esri.layers.TileInfo({
"rows": 256,
"cols": 256,
"compressionQuality": 0,
"origin": {
"x": -180,
"y": 90
},
"spatialReference": {
"wkid": 4326
},
"lods": [
{ "level": 2, "resolution": 0.3515625, "scale": 147748796.52937502 },
{ "level": 3, "resolution": 0.17578125, "scale": 73874398.264687508 },
{ "level": 4, "resolution": 0.087890625, "scale": 36937199.132343754 },
{ "level": 5, "resolution": 0.0439453125, "scale": 18468599.566171877 },
{ "level": 6, "resolution": 0.02197265625, "scale": 9234299.7830859385 },
{ "level": 7, "resolution": 0.010986328125, "scale": 4617149.8915429693 },
{ "level": 8, "resolution": 0.0054931640625, "scale": 2308574.9457714846 },
{ "level": 9, "resolution": 0.00274658203125, "scale": 1154287.4728857423 },
{ "level": 10, "resolution": 0.001373291015625, "scale": 577143.73644287116 },
{ "level": 11, "resolution": 0.0006866455078125, "scale": 288571.86822143558 },
{ "level": 12, "resolution": 0.00034332275390625, "scale": 144285.93411071779 },
{ "level": 13, "resolution": 0.000171661376953125, "scale": 72142.967055358895 },
{ "level": 14, "resolution": 8.58306884765625e-005, "scale": 36071.483527679447 },
{ "level": 15, "resolution": 4.291534423828125e-005, "scale": 18035.741763839724 },
{ "level": 16, "resolution": 2.1457672119140625e-005, "scale": 9017.8708819198619 },
{ "level": 17, "resolution": 1.0728836059570313e-005, "scale": 4508.9354409599309 },
{ "level": 18, "resolution": 5.3644180297851563e-006, "scale": 2254.4677204799655 }
]
});
this.loaded = true;
this.onLoad(this);
},
getTileUrl: function (level, row, col) {
return "http://t" + col % 8 + ".tianditu.cn/vec_c/wmts?SERVICE=WMTS&REQUEST=GetTile&VERSION=1.0.0&LAYER=vec&STYLE=default&TILEMATRIXSET=c&TILEMATRIX=" + level + "&TILEROW=" + row + "&TILECOL=" + col + "&FORMAT=tiles";
}
});
});

2、切片标注——TDTAnnoLayer.js

[javascript] view plaincopy print?

define(["dojo/_base/declare",
"esri/layers/tiled"],
function (declare) {
return declare(esri.layers.TiledMapServiceLayer, {
constructor: function () {
this.spatialReference = new esri.SpatialReference({ wkid: 4326 });
this.initialExtent = (this.fullExtent = new esri.geometry.Extent(-180.0, -90.0, 180.0, 90.0, this.spatialReference));
this.tileInfo = new esri.layers.TileInfo({
"rows": 256,
"cols": 256,
"compressionQuality": 0,
"origin": {
"x": -180,
"y": 90
},
"spatialReference": {
"wkid": 4326
},
"lods": [
{ "level": 2, "resolution": 0.3515625, "scale": 147748796.52937502 },
{ "level": 3, "resolution": 0.17578125, "scale": 73874398.264687508 },
{ "level": 4, "resolution": 0.087890625, "scale": 36937199.132343754 },
{ "level": 5, "resolution": 0.0439453125, "scale": 18468599.566171877 },
{ "level": 6, "resolution": 0.02197265625, "scale": 9234299.7830859385 },
{ "level": 7, "resolution": 0.010986328125, "scale": 4617149.8915429693 },
{ "level": 8, "resolution": 0.0054931640625, "scale": 2308574.9457714846 },
{ "level": 9, "resolution": 0.00274658203125, "scale": 1154287.4728857423 },
{ "level": 10, "resolution": 0.001373291015625, "scale": 577143.73644287116 },
{ "level": 11, "resolution": 0.0006866455078125, "scale": 288571.86822143558 },
{ "level": 12, "resolution": 0.00034332275390625, "scale": 144285.93411071779 },
{ "level": 13, "resolution": 0.000171661376953125, "scale": 72142.967055358895 },
{ "level": 14, "resolution": 8.58306884765625e-005, "scale": 36071.483527679447 },
{ "level": 15, "resolution": 4.291534423828125e-005, "scale": 18035.741763839724 },
{ "level": 16, "resolution": 2.1457672119140625e-005, "scale": 9017.8708819198619 },
{ "level": 17, "resolution": 1.0728836059570313e-005, "scale": 4508.9354409599309 },
{ "level": 18, "resolution": 5.3644180297851563e-006, "scale": 2254.4677204799655 }
]
});
this.loaded = true;
this.onLoad(this);
},
getTileUrl: function (level, row, col) {
return "http://t" + row % 8 + ".tianditu.cn/cva_c/wmts?SERVICE=WMTS&REQUEST=GetTile&VERSION=1.0.0&LAYER=cva&STYLE=default&TILEMATRIXSET=c&TILEMATRIX=" + level + "&TILEROW=" + row + "&TILECOL=" + col + "&FORMAT=tiles";
}
});
});

封装好之后就可以在页面调用了，调用的时候需要导入这些自定义的图层，导入方式为：

[javascript] view plaincopy print?

<script type="text/javascript">
dojoConfig = {
parseOnLoad: true,
packages: [{
name: 'tdlib',
location: this.location.pathname.replace(/\/[^/]+$/, "")+"/js/tdlib"
}]
};
</script>
<script src="http://localhost/arcgis_js_api/library/3.9/3.9/init.js"></script>
<script>
require(["tdlib/TDTLayer",
"tdlib/TDTAnnoLayer"],
function (TDTLayer,
TDTAnnoLayer
){
var basemap = new TDTLayer();
map.addLayer(basemap);
var annolayer = new TDTAnnoLayer();
map.addLayer(annolayer);
});
</script>

完整调用页面代码为：

[html] view plaincopy print?

<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>TianDi Map</title>
<link rel="stylesheet" href="http://localhost/arcgis_js_api/library/3.9/3.9/js/dojo/dijit/themes/tundra/tundra.css">
<link rel="stylesheet" href="http://localhost/arcgis_js_api/library/3.9/3.9/js/esri/css/esri.css">
<style>
html, body, #map {
height: 100%;
margin: 0;
padding: 0;
}
</style>
<script type="text/javascript">
dojoConfig = {
parseOnLoad: true,
packages: [{
name: 'tdlib',
location: this.location.pathname.replace(/\/[^/]+$/, "")+"/js/tdlib"
}]
};
</script>
<script src="http://localhost/arcgis_js_api/library/3.9/3.9/init.js"></script>
<script>
var map;
require(["esri/map",
"tdlib/TDTLayer",
"tdlib/TDTAnnoLayer",
"esri/layers/FeatureLayer",
"esri/geometry/Point",
"esri/symbols/SimpleFillSymbol",
"esri/symbols/SimpleLineSymbol",
"dojo/_base/Color",
"dojo/domReady!"],
function (Map,
TDTLayer,
TDTAnnoLayer,
FeatureLayer,
Point,
SimpleFillSymbol,
SimpleLineSymbol,
Color
){
map = new Map("map", { logo: false });
var basemap = new TDTLayer();
map.addLayer(basemap);
var annolayer = new TDTAnnoLayer();
map.addLayer(annolayer);
var pro = new FeatureLayer("http://localhost:6080/arcgis/rest/services/chinawgs84/MapServer/1");
map.addLayer(pro);
var pt = new Point(103.847, 36.0473);
map.centerAndZoom(pt, 3);
});
</script>
</head>
<body>
<div id="map"></div>
</body>
</html>

在图中，我还添加了一个我本机用Arcgis Server发布的特征层，完成后效果如下：
