Earth observation has entered a golden era in which a growing fleet of public and commercial satellites acquire an unprecedented volume of high-quality data across the entire electromagnetic spectrum. Yet, a major limitation hindering the effective exploitation of this wealth of Earth observation data is a shortfall of dedicated data centres offering the high performance processing capabilities needed to process multi-year global data sets at a fine spatial resolution. Therefore, there is the high need to build up science-driven platforms that are transparent for their users and offer a high diversity and flexibility in terms of the data sets and algorithms used. Recognizing this need, TU Wien founded the EODC Earth Observation Data Centre together with other Austrian partners in May 2014 as a public-private partnership. The mission of EODC is to work together with its partners from science, the public and the private sectors in order to foster the use of Earth observation data for monitoring of global environmental processes. To archive this the EODC partners have been working together to establish a federated IT infrastructure capable of storing and processing Petabytes of satellite data. The central site of this infrastructure is the Science Centre Arsenal of TU Wien, where a cloud platform and storage system have been set up and connected to the Vienna Scientific Cluster (VSC). This infrastructure has been continually upgraded since 2014, offering access to a Petabyte-scale satellite data archive and capabilities for processing of high-resolution satellite images (e.g. 10 m Sentinel-1 radar images) on a global scale.

Methoden & Expertise zur Forschungsinfrastruktur
The EODC infrastructure at TU Wien allows for the possibility to remotely access one’s workspace from anywhere and at the same time directly access all available EO data without the need to download them to a processing system. Users may connect from their own PC to
(1) a cloud infrastructure, which provides users with virtual machines (VM) for developing and testing the methods, as well as visualizing the results on small spatio-temporal extents.
(2) storages for accessing EO data in the public part of the archive and for storing results in private folders. The storage is realised as a high-performance GPFS clustered file system with a net disk capacity of several Petabytes and a robotic tape library.
(3) the VSC-3 supercomputer, through dedicated login nodes, and, subsequently, the computing nodes.
