1. A concise explanation of the problem you’re experiencing.
Hello! I am trying to style GeoJSON polygons by SymbolID (a field with values from 0-3). I’m very new to Cesium and I’m loving how much great documentation is out there but I think I’m missing something somewhere.
2. A minimal code example. If you’ve found a bug, this helps us reproduce and repair it.
var promise = Cesium.GeoJsonDataSource.load(‘my_geojson_file’);
promise.then(function (dataSource) {
viewer.dataSources.add(dataSource);
var entities = dataSource.entities.values;
var colourhash = {};
for (var i = 0; i < entities.length; i++) {
var entity = entities[i];
var symID = entity.SymbolID;
var colour = colourhash[symID];
if (colour === 2) {
colour = Cesium.Color.FORESTGREEN({
alpha: 1.0
});
colourhash[symID] = colour;
}
entity.polygon.material = colour;
entity.polygon.extrudedHeight = entity.properties.Height;}
3. Context. Why do you need to do this? We might know a better way to accomplish your goal.
The GeoJSON polygons represent a heatmap, I’m trying to symbolize them to a set colours that correspond to some categories. I used this example in the sandbox to help create my code.
4. The Cesium version you’re using, your operating system and browser.
