Windows on Earth is at its core, an educational and scientific endeavor striving to share in the wonders, beauty, and majesty of our "Little Blue Marble" known as Earth. Over the last 10 years we've created software to help the crew of the International Space Station (ISS) capture photographs of their favorite locations around the world in order to share their unique and breathtaking vantage with the public, imparting a greater appreciation for our home and some perspective on how interconnected we all are.
Applications within the Windows on Earth project fall into a few categories:
Since discovering Cesium in the summer of 2013 and spending time over the early fall creating many proofs-of-concept which focused on the feasibility of replacing "Google Earth plugin", we quickly came to the realization that we never wanted to go back. Even when Cesium was in its beta release phase, the ease of use and the stability shamed the much more mature Google Earth plugin.
Every project is going to have its own needs and requirements so your list may vary, but here is why we made the change: ease of integration, stability, performance, access to the camera's field of view, offline functionality, quality of the documentation, open-source code (so we can debug if necessary), and the ability to use custom imagery providers so we can utilize satellite imagery specially created for our project.
