Present CityGML Data as Cesium 3D Tiles

The CityGML format is an official standard of the Open Geospatial Consortium (OGC). CityGML 3D models are made from sets of XML files that can be accompanied by images to provide textures. While these models are full of data and can be used in a variety of programs, they are not the best format when it comes to streaming and rendering over the internet. Optimize your CityGML models for the web by using FME to convert them to Cesium 3D Tiles and share them with others easily across the web!

Clamp Plans To Reality

When you convert your CityGML buildings, furniture, vegetation and other city objects to Cesium 3D Tiles, you will be able to display your models directly on terrains based on the real world. After using FME transformers to parse your data, assign attribute values for adaptive tiling to control various levels of detail for different scales of viewing. This is perfect for sharing your data and streaming it over the internet!

Automate CityGML to Cesium

If you have many 3D city models and landscapes to convert, don’t worry! FME Server can run your conversion workflows on new data automatically. Simply set up a schedule or assign events and your data will be processed in no time. While your workflows are running in the background, explore your data in Cesium! Try drawing geometries, create time-dynamic scenes, or add realistic visual effects like shadows, stars, or smoke!
