Awesome Sentinel

The Copernicus Sentinel satellites are an amazing opportunity for people all over the world to explore unprecedented amounts of remote sensing data under a free and open license. The collaborative nature of the Copernicus programme means that there are multiple ways to get access to Sentinel satellite data and the open license allows anyone to host mirrors of the data. The definitive data access portal for Sentinel data is the Copernicus Open Access Hub aka. SciHub. It contains all Sentinel-1, -2 and -3 data since their respective launches and offers a graphical search interface as well as an API. It is based on the open-source data hub software, which is also employed by most national mirrors. There are however a wide number of mirrors and tools to get the data and process it. This post is a curated list of awesome tools, tutorials and APIs related to the Copernicus Sentinel Satellites.
