【WebGL】WebGl加载GeoJSON报错：Unknown crs name: urn:ogc:def:crs:EPSG:4547

Answer 1

【解决方案】默认不支持4547的坐标系，在加载之前要定义一下Cesium.GeoJsonDataSource.crsNames['urn:ogc:def:crs:EPSG::4547']，参考代码： Cesium.GeoJsonDataSource.crsNames['urn:ogc:def:crs:EPSG::4547']; var promise = Cesium.GeoJsonDataSource.load("./data/json/0-12-0.geojson"); promise.then(function(dataSource) { viewer.dataSources.add(dataSource) });
