  We present a distributed system for storage, processing, three-dimensional
visualisation and basic analysis of data from Earth-observing satellites. The
database and the server have been designed for high performance and
scalability, whereas the client is highly portable thanks to having been
designed as a HTML5- and WebGL-based Web application. The system is based on
the so-called MEAN stack, a modern replacement for LAMP which has steadily been
gaining traction among high-performance Web applications. We demonstrate the
performance of the system from the perspective of an user operating the client.
