Dear Sir,

I am using reactJS

here is my code

this.state.Viewer.dataSources.add(this.state.Cesium.GeoJsonDataSource.load(‘data/adu_governorate…geojson’, {

stroke: this.state.Cesium.Color.HOTPINK,

fill: this.state.Cesium.Color.PINK.withAlpha(0.5),

strokeWidth: 3

}));

Thank you

I believe this is happening because the terrain is occluding the polygon. Try setting your geoJSON to clamp to ground by setting “clampToGround: true” in the load options:
