3 -**Earth Observation** (EO) gathers information from our planet from a distance using satellite or airborne data, such as unmanned aerial vehicles. These techniques can be used **for a large number of applications**, to name a few:

5 -* environmental and nature protection (e.g. habitat mapping or oil spill detection);
6 -* agriculture (e.g. crop condition monitoring and yield predictions);
7 -* forestry (e.g. tree species classification and timber stock estimations);
8 -* climate change (i.e. detecting sea ice and water levels); and
9 -* urban development (e.g. urban planning and urban sprawl monitoring).
17 +XWiki is the best tool to organize your knowledge. A //wiki// is organized in a hierarchy of //pages//. You can create multiple wikis, each with its own set of pages.

11 -The European **Copernicus programme** is operating and expanding an extensive constellation consisting of various EO satellites carrying a range of different sensors, such as **Sentinel-1** fitted with an all-weather, day-and-night radar system and **Sentinel-2** equipped with a multispectral high-resolution sensor. In total six different Sentinels are planned with each having multiple satellites. Sentinel-1 and Sentinel-2 have a revisit time of three and respectively five days, in effect provide a **global coverage every three and five days**. These are long-term operated and will be collecting data for the upcoming decades. The current seven operation Sentinels collect daily 15TB of raw data, thus an extensive archive of EO data needs to be maintained.
19 +XWiki can be used as a knowledge base (support, documentation, sales, etc.), for collaborative workspaces or even as a complete intranet.

13 -The **massive volumes of data** provided by the Copernicus programme need to be processed to higher-level products to unlock their full potential. For instance, Sentinel-1s’ raw radar data can be transformed to level-1 products (single look complex and ground range detection) or level-2 ocean products, while the data provided by Sentinel-2 needs to be athmospherically corrected to level-2A. **These transformations require**: a) know-how on where to retrieve the data, b) programming experience to implement the algorithms, c) large amounts of disk space, and d) ample processing power. All these factors are limiting the uptake of satellite data and result in a high entry level, requiring specific technical skills, software and hardware.
21 += The basics =

15 -The **Austrian Data Cube** project delivers a system mitigating these negative effects, making Copernicus data available to the broad public. The consortium of five Austrian partners introduces a state-of-the-art infrastructure integrating a cloud-based data cube concept for Austria. The data cube concept stores data in a gridded multi-dimensional database capable of** providing time-series of highly standardized and harmonized radiometrically and geometrically corrected satellite data**. These higher-level data are made available through a user-friendly and standardized interface, with QGIS and web map services plugins (WMS) for novel users and a dedicated application programming interface (API) for advance users. The benefits include cloud-based storage and processing, so users can directly download the ready-to-use data for their specific region of interest, without performing the time-consuming pre-processing steps. In addition, the scalable service allows for integration of user relevant geodata (e.g. digital elevation model, leaf area index, open street maps).
