In this exercise you will learn how to transform data from CityGML into the Indexed 3D Scene Layer (I3S) format from ESRI and into the 3D tiles format from Cesium. The new formats can then be displayed by their native web viewers or by a third party visualization framework. Tweaking the visualization to display thematic coloring of the 3D models will also be included in this exercise.The transformation will be done with the feature manipulation engine (FME).

The separate steps:

1. Open source datasets
2. Feature manipulation engine (FME)
3. Visualization with CesiumJS
4. Visualization with ArcGIS
5. Visualization with Deck.gl
