I have installed geoserver, qgis-server and I am serving raster tiles styling them using openlayers on a local network. Now I need to serve 3d-maps... Can I run cesium on a standalone local network for this(no internet connectivity)?

Cesium offers an Offline Demo that shows how to turn off the things that talk to external networks by default.

var viewer = new Cesium.Viewer("cesiumContainer", {
  imageryProvider: new Cesium.TileMapServiceImageryProvider({
    url: Cesium.buildModuleUrl("Assets/Textures/NaturalEarthII"),
  }),
  baseLayerPicker: false,
  geocoder: false,
});

Primarily, the baseLayerPicker and geocoder should be turned off, as they use external services. The imageryProvider shown here is Natural Earth II, but you can swap that out with your own imagery service.

Alternately, the baseLayerPicker can be left enabled, but you can empty out its contents and replace them with your own local-network imagery provider selections.

  • Thanks a ton. I was able to add my WMS imagery layers from QGIS-Server on to cesium. How do I use my own terrian(dem files) to present the elevation data.

  • Glad it helped! If you have an additional question, such as the one about dem files in the comments, do a quick search to see if this site already has the same question posted. If not, go ahead and post that as a new question, along with code showing what you've tried and what's not working.

To complement emackey's answer, you may have a local OpenStreetMap to serve your base map (https://github.com/Overv/openstreetmap-tile-server) .

var viewer = new Cesium.Viewer("cesiumContainer", {
  imageryProvider: new Cesium.UrlTemplateImageryProvider({
    url: '<YOUR_OSM_SERVER>/tile/{z}/{x}/{y}.png',
    maximumLevel: 25,
    hasAlphaChannel: false,
    enablePickFeatures: false
  }),
  baseLayerPicker: false,
  geocoder: false,
});

The result is very cool.

  • Thanks I was able to overlay my raster tiles as flat WMS imagery on cesium. Now I want to use my own terrain data(DEM files) to get the 3D effect, suggestions please .

  • Yeap! It is a bit simple at first but I need to you to create a new question so I can explain. And you will need a LOT of disk space. Half of South America eats 700GB of my disk.

You can try here and even produce your custom terrain.

You can preview and download server software for free aswell

https://portal.terrainserver.com

Note: I am the provider for that service
