The Institute for Earth Observation is collecting a huge number of Sentinel data within the Sentinel Alpine Observatory (SAO) initiative. To handle these data a service catalogue is available. This catalogue offers the possibility to publish data at different scales and metadata. In particular, users can access raster data and scientifically derived products together with their corresponding descriptive information at various levels.
Metadata summarizes basic information about data. Since they act as generalized properties, users can filter through data using name, location, time, or sensor type. The records in the catalogue are in XML format encoded in UTF-8 characters.
Sentinel raw data delivered by ESA (European Spatial Agency) already have their own metadata. But since they are different among the different missions, Eurac Research derives Sentinel metadata using an XSLT transformation. These metadata are fully compliant with ISO-19139 (describing geospatial data) as well as INSPIRE and OGC CSW (Catalog Services for the Web) requirements. This enables us to have the same structure for all the Sentinel data. The derived maps or products in general follow the same standards as well. In this case the owner of the product follows the template indicated in the catalogue itself to create the metadata. The insertion of the metadata for the raw data is daily as soon as a pass over the Alpine area is available. All the Sentinel-2 derived maps will be published as soon as they are scientifically validated by the researchers.
The main goal of this environment is to increase the exchange of information. The usage of organized and well documented data following international standards can facilitate and speed up cooperation between scientific communities.
