This is a Terrain Provider for Cesium Elevation si request from a WCS 2.0.1 endpoint. This provider has been tested with a Geoserver Response of the WCS is a geotiff which is parsed with GeotiffParser.js in order to obtain the heightmap.
In the withIndexedDB directory there is a version of the WCSTerrainProvider.js which use IndexedDB (TileCacheService.js) to store heightmap.
WCSTerrainProvider in action :
How to use it :
First you need to provide the Elevation throught a WCS Service. I use Geoserver for doing that. For my example I have installed a Geoserver under a Tomcat on my computer. I can access the WCS by this URL : http://localhost:8080/geoserver/wcs
For Cesium, I needed to initialize the terrainProvider as follow :
var WCSTerrainProvider = new Cesium.WCSTerrainProvider({
service: "WCS",
url: "http://localhost:8080/geoserver/wcs",
layerName: "layerName",
bbox: [longitude - 0.1, latitude - 0.1, longitude + 0.1, latitude + 0.1],
waterMask: false
});
cesiumContainer.scene.terrainProvider = WCSTerrainProvider;
