Abstract :
[en] In this thesis, we assessed the capability of the Rasdaman software as a full-scale raster data server. In the domain of Geographic Information Systems (GIS), data servers hold an even more prominent position than in traditional information systems. Currently, many solutions, both private and open source, exist for vectorial data and have been extensively tested on practical project. However, solutions for raster data are scarcer. Of the few available solutions, we explored Rasdaman, a rather generic software for multi-dimensional arrays (MDA). As it turns out, Rasdaman has no built-in support for Geographic Coordinate Systems (GCS) and, as such, cannot be used alone, in spite of its MDA language which makes it a strong candidate for web services. Nonetheless, GCS can be build on top of Rasdaman and actually is in the form of a Petascope plugin. All in all, the combination Rasdaman, Petascope and PostGIS make for a powerful and flexible data server for both vector and raster data.

Rasdaman, the software analyzed in this master thesis, has evolved significantly since our assessment. It would be interesting to reevaluate its capability as a raster data server.
