GeoJson outline style missing

CesiumJS
1

Hi there,

I tried to use GeoJsonDataSource to input GeoJson format dataset with the following link as the reference Cesium Sandcastle
Below is the sample of input method:

const geojsonlayer = await Cesium.GeoJsonDataSource.load(geojsonurl, {
        clampToGround: true,
        stroke: Cesium.Color.HOTPINK,
        fill: Cesium.Color.PINK.withAlpha(0.5),
        strokeWidth: 3,
      });
      const dataSource = await this.viewer.dataSources.add(geojsonlayer);
      console.log(dataSource);
      for (const entity of dataSource.entities.values) {
        if (entity.polygon) {
          entity.polygon.classificationType = Cesium.ClassificationType.BOTH;
          // entity.polygon.material = Cesium.Color(255, 0, 0, 0.5);
          console.log(entity.polygon);
        }
        if (entity.polyline) {
          console.log(entity.polyline);
          entity.polyline.classificationType = Cesium.ClassificationType.BOTH;
        }
      }

We are expecting the result as below,

But this is how is it shows in reality,

Do we have anything missed in the setting please?

Hi there,

welcome any comment or feedback.

Hi @Joechen,

Do you have terrain enabled in your example? Polygon outlines are not currently supported on terrain, but there are some workarounds, like setting the polygon’s height to 0.

Otherwise, it would be helpful if you could provide the GeoJSON in question so we can troubleshoot.

Thanks,
