The Google Earth API is going away and many developers are moving to Cesium. Cesium is built on modern plugin-free tech, and is cross-platform, cross-browser, open-source, and actively developed by a large community.
Here you'll find technical resources for moving from Google Earth to Cesium.
Build on what you already know. Here are two tutorials specifically targeted at helping you make the switch from Google Earth to Cesium:
The benefits of Cesium and how to build Hello World.
Major coding concepts in Cesium and how they differ from GE.
Hear firsthand from developers who moved from GE to Cesium.
Introduction to Cesium in the face of Google Earth deprecation.
Check out these highlighted apps that moved from GE to Cesium.
