The ease to build beautiful looking applications with celsius, best documentation i have come across so far which covers almost every topic you might need it too! Highly Recommendable software as compared other JS-based globe and map libs out there! It can run smoothly even at slow speed computers or old PC's like mine (Pentium 4 1 Ghz AMD graphics card). I am yet using all features of this great tool but those being available are amazing enought already. If we cannot find anything that needs improvement about its current implementation then no doubt, just go ahead an install Celsius :) Easy integration capabilities makes building world wide application much easier than what normally should be done while working remotely over different time zones such us me who work from India/Nepal where my home city has multiple times difference with respect weather etcetera. The 3D globe is one of the best feature of the Cesium. It's very easy to create a globe and it's very easy to customize the globe. The only problem i have with the Cesium is that sometimes it's a little bit slow. Sometimes it takes a lot of time to load the map. I would like to recommend this product to other users. I am using Cesium for my personal project. I am creating a 3D globe to show the location of my friends. The map is very useful to show the location of my friends.
