This document discusses 3D mapping technologies and challenges. It highlights how Esri introduced vertical datum transformations in ArcGIS 10.4 to properly display 3D objects. It also describes how a 30GB point cloud of London with nearly a million buildings can be streamed and rendered online in real-world coordinates using JavaScript APIs. The document encourages using these new capabilities and APIs to build interactive 3D applications.
