接上篇博客,下载好arcgis格式的瓦片数据以后,需要用js客户端在前端加载出来。这里介绍两种方案:
1、使用超图iServer将瓦片发布成rest地图服务,或者arcgis地图服务,客户端直接加载
2、将瓦片部署到tomcat服务器下,使用js客户端解析加载
备注:arcgis-js客户端的本地部署见博客:
使用iServer发布成服务对接
1、在iServer管理界面,点击发布arcgis缓存
2、选择发布rest地图服务和arcgis地图服务
3、发布完成后的服务地址
http://localhost:8090/iserver/services/map-agscache-0313/arcgisrest/0313/MapServer
http://localhost:8090/iserver/services/map-agscache-0313/rest js预览地图服务如下:
4、使用arcgis-js请求发布的MapServer服务,代码如下:
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <meta name="viewport" content="initial-scale=1,maximum-scale=1,user-scalable=no"> <title>Load a basic WebMap - 4.3</title> <style> * { padding: 0; margin: 0; } html, body, #viewDiv { padding: 0; margin: 0; height: 100%; 100%; } </style> <script> var dojoConfig = { async: true, packages: [{ name: "js", location: location.pathname.replace(//[^/]*$/, '') + '/js' }] }; </script> <link rel="stylesheet" href="http://localhost:8090/arcgis_js_api/library/3.25/3.25/dijit/themes/tundra/tundra.css"> <link rel="stylesheet" href="http://localhost:8090/arcgis_js_api/library/3.25/3.25/esri/css/esri.css"> <script type="text/javascript" src="http://localhost:8090/arcgis_js_api/library/3.25/3.25/init.js"></script> <script type="text/javascript"> var map; require(["esri/map", "esri/layers/ArcGISDynamicMapServiceLayer", "esri/layers/ImageParameters", "esri/geometry/Extent", "esri/SpatialReference", ], function (Map, ArcGISDynamicMapServiceLayer, ImageParameters, Extent, SpatialReference) { map = new Map("mapDiv"); var imageParameters = new ImageParameters(); imageParameters.format = "png"; //set the image type to PNG24, note default is PNG8. var extent = new esri.geometry.Extent( -6332699.066701883,-14857661.096458122, 25217355.589120373,33742317.61887661, new SpatialReference({ wkid: 3857 })); var dynamicMapServiceLayer = new ArcGISDynamicMapServiceLayer( "http://localhost:8090/iserver/services/map-agscache-0313/arcgisrest/0313/MapServer", { id: "base", "opacity": 1.0, "imageParameters": imageParameters, "fullExtent": extent, "disableClientCaching": true }); map.addLayer(dynamicMapServiceLayer); }); </script> </head> <body> <div id="mapDiv"></div> </body> </html>
使用arcgis-js直接对接
1、基于TiledMapServiceLayer封装一个layer,将瓦片数据直接放到tomcat目录下即可,其中数据范围,坐标系,中心点,比例尺级别等在瓦片数据的.cdi和.xml中有记录
define(["dojo/_base/declare", "esri/layers/TiledMapServiceLayer", "esri/SpatialReference", "esri/geometry/Extent", "esri/layers/TileInfo"], function (declare, TiledMapServiceLayer) { return declare('customTileLyr', TiledMapServiceLayer, { //没定义类名,就以文件名为准 第一个参数是父类 constructor: function (baseUrl) { this.url = baseUrl; //下面的参数信息参考2中的截图 this.spatialReference = new esri.SpatialReference({ wkid: 102113 }); this.initialExtent = this.fullExtent = new esri.geometry.Extent(13738103.530723013000000, 5123421.131898794300000, 13743912.744872687000000, 5128007.353595904100000, this.spatialReference); this.tileInfo = new esri.layers.TileInfo({ "rows": 256, "cols": 256, "compressionQuality": 0, "origin": { "x": -20037508.342787001, "y":20037508.342787001 }, "spatialReference": { "wkid": 102113 }, "lods": [ { "level": 0, "resolution": 156543.033928, "scale": 591657527.591555 }, { "level": 1, "resolution": 78271.5169639999, "scale": 295828763.795777 }, { "level": 2, "resolution": 39135.7584820001, "scale": 147914381.897889 }, { "level": 3, "resolution": 19567.8792409999, "scale": 73957190.948944 }, { "level": 4, "resolution": 9783.93962049996, "scale": 36978595.474472 }, { "level": 5, "resolution": 4891.96981024998, "scale": 18489297.737236 }, { "level": 6, "resolution": 2445.98490512499, "scale": 9244648.868618 }, { "level": 7, "resolution": 1222.99245256249, "scale": 4622324.434309 }, { "level": 8, "resolution": 611.49622628138, "scale": 2311162.217155 }, { "level": 9, "resolution": 305.748113140558, "scale": 1155581.108577 }, { "level": 10, "resolution": 152.874056570411, "scale": 577790.554289 }, { "level": 11, "resolution": 76.4370282850732, "scale": 288895.277144 }, { "level": 12, "resolution": 38.2185141425366, "scale": 144447.638572 }, { "level": 13, "resolution": 19.1092570712683, "scale": 72223.819286 }, { "level": 14, "resolution": 9.55462853563415, "scale": 36111.909643 }, { "level": 15, "resolution": 4.77731426794937, "scale": 18055.954822 }, { "level": 16, "resolution": 2.38865713397468, "scale": 9027.977411 }, { "level": 17, "resolution": 1.19432856685505, "scale": 4513.988705 }, { "level": 18, "resolution": 0.597164283559817, "scale": 2256.994353 }, { "level": 19, "resolution": 0.29858214164761665, "scale": 1128.4971760000001 }, ] }); this.loaded = true; this.onLoad(this); }, getTileUrl: function (level, row, col) { return "http://localhost:8090/0318-data/_alllayers/" + "L" + dojo.string.pad(level, 2, '0') + "/" + "R" + dojo.string.pad(row.toString(16), 8, '0').toUpperCase() + "/" + "C" + dojo.string.pad(col.toString(16), 8, '0').toUpperCase() + "." + "jpg"; } }); });
2、web页面,初始化上面封装的layer
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <meta name="viewport" content="initial-scale=1,maximum-scale=1,user-scalable=no"> <title>Load a basic WebMap - 4.3</title> <style> * { padding: 0; margin: 0; } html, body, #viewDiv { padding: 0; margin: 0; height: 100%; 100%; } </style> <script> var dojoConfig = { async: true, packages: [{ name: "js", location: location.pathname.replace(//[^/]*$/, '') + '/js' }] }; </script> <link rel="stylesheet" href="http://localhost:8090/arcgis_js_api/library/3.25/3.25/dijit/themes/tundra/tundra.css"> <link rel="stylesheet" href="http://localhost:8090/arcgis_js_api/library/3.25/3.25/esri/css/esri.css"> <script type="text/javascript" src="http://localhost:8090/arcgis_js_api/library/3.25/3.25/init.js"></script> <script type="text/javascript"> var map; require(["esri/map", "js/customTiledLyr"], function (Map, customTiledLyr) { map = new Map("mapDiv"); var tileUrl = 'http://localhost:8090/0318-data/_alllayers/'; var customTileLyr = new customTiledLyr(tileUrl); map.addLayer(customTileLyr); }); </script> </head> <body> <div id="mapDiv"></div> </body> </html>
3、运行测试页面,加载效果如下:
