arcgis api for javascipt 加载天地图、百度地图

写在前面的话：

1.百度地图是自己定义的坐标系统，wkid=102100.百度地图数据是加密的产物。下文将附上百度坐标与WGS84，谷歌等坐标系统转换方法（地理-地理），此方法并未亲测，据说准

2.百度地图可以直接加载经纬度坐标

3.百度地图如果加载的arcgis api中会出现坐标偏移，1.中已经解决了地理坐标转换，那么找到百度投影-地理坐标的转换方式，则arcgis就可以直接无偏加载了，网上很多方法，但是亲测不行。

4.天地图不是涉密数据，根据本文提供的类库,arcgis api for js可以直接加载。但是数据有略微的偏移

 

 

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

 

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,

                    },

                        { "level": 11, "resolution": 0.0006866455078125, "scale": 288571.86822143558 },
                        { "level": 12, "resolution": 0.00034332275390625, "scale": 144285.93411071779 },

                        { "level": 14, "resolution": 8.58306884765625e-005, "scale": 36071.483527679447 },

                });
                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

 

 

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": {

                        "y": 90
                    },
                    "spatialReference": {
                        "wkid": 4326
                    },
                    "lods": [

                        { "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：

 

 

    <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>

百度地图可调用的有地图切片，影像切片，以及道路等POI切片，我将之用TiledMapServiceLayer做了扩展，成了BDAnoLayer，BDVecLayer，BDimgLayer三个图层，其代码如下：

BDAnoLayer.js
