Managing big, linked, and open earth-observation data: Using the TELEIOS\/LEO software stack

摘要

Big, open Earth Observation data that are currently made available by space agencies are not following the linked data paradigm. Therefore, from the perspective of a user, the Earth Observation data and other kinds of geospatial data necessary to satisfy his or her information need can only be found in different data silos, where each silo may contain only part of the needed data. Opening up these silos by publishing their contents as RDF and interlinking them with semantic connections allows the development of data analytics applications with great environmental and financial value. In this paper, we present the life-cycle of big, linked and open Earth Observation data and we show how to support its various stages using the software stack developed by the projects EU research projects TELEIOS and LEO. We also show this stack of tools can be used to implement a wild fire monitoring service.
