Cesium加载各类服务数据

一、地形数据

1. 源码

//初始化地形数据
        const demLayer: CesiumTerrainProvider = new Cesium.CesiumTerrainProvider({
            url: url,
            requestVertexNormals: true,
        });
//加载地形数据
viewer.terrainProvider = demLayer
//隐藏 直接置空
viewer.terrainProvider = new Cesium.EllipsoidTerrainProvider({});
//恢复重新赋值

二、ImageryLayer 类型数据

ArcGisMapServerImageryProvider
BingMapsImageryProvider
OpenStreetMapImageryProvider
TileMapServiceImageryProvider
GoogleEarthEnterpriseImageryProvider
GoogleEarthEnterpriseMapsProvider
GridImageryProvider
IonImageryProvider
MapboxImageryProvider
MapboxStyleImageryProvider
SingleTileImageryProvider
TileCoordinatesImageryProvider
UrlTemplateImageryProvider
WebMapServiceImageryProvider
WebMapTileServiceImageryProvider

 

1.UrlTemplateImageryProvider

dom影像数据 代码

// xyz格式
const url = 'https://yoururl/{Time}/{z}/{y}/{x}.png'
const provider: UrlTemplateImageryProvider = new Cesium.UrlTemplateImageryProvider({ url: url, rectangle: rec, maximumLevel: maxlevel, minimumLevel: minlevel, }) as UrlTemplateImageryProvider;
viewer.scene.imagerlayers.addImageryProvider(provider)

 2.ArcGisMapServerImageryProvider

//arcgis mapserver
    let arcgisMapServer = new Cesium.ArcGisMapServerImageryProvider({
      url: url,
      tilingScheme: new Cesium.WebMercatorTilingScheme(),
    });

  viewer.scene.imageryLayers.addImageryProvider(arcgisMapServer);

3.WebMapTileServiceImageryProvider

//kvp
const shadedRelief1 = new Cesium.WebMapTileServiceImageryProvider({
    url : 'http://basemap.nationalmap.gov/arcgis/rest/services/USGSShadedReliefOnly/MapServer/WMTS',
    layer : 'USGSShadedReliefOnly',
    style : 'default',
    format : 'image/jpeg',
    tileMatrixSetID : 'default028mm',
    // tileMatrixLabels : ['default028mm:0', 'default028mm:1', 'default028mm:2' ...],
    maximumLevel: 19,
    credit : new Cesium.Credit('U. S. Geological Survey')
});
viewer.imageryLayers.addImageryProvider(shadedRelief1);

//restful
const shadedRelief2 = new Cesium.WebMapTileServiceImageryProvider({
    url : 'http://basemap.nationalmap.gov/arcgis/rest/services/USGSShadedReliefOnly/MapServer/WMTS/tile/1.0.0/USGSShadedReliefOnly/{Style}/{TileMatrixSet}/{TileMatrix}/{TileRow}/{TileCol}.jpg',
    layer : 'USGSShadedReliefOnly',
    style : 'default',
    format : 'image/jpeg',
    tileMatrixSetID : 'default028mm',
    maximumLevel: 19,
    credit : new Cesium.Credit('U. S. Geological Survey')
});
viewer.imageryLayers.addImageryProvider(shadedRelief2);

 4.WebMapServiceImageryProvider

    let wmsProvider= new Cesium.WebMapServiceImageryProvider({
      url:url,
      layers: layer,
      parameters: parameters,
      rectangle:rectangle,
    });
    viewer.scene.imageryLayers.addImageryProvider(
      wmsProvider
    );
