The integrity of the schematic heterogeneity of Moroccan geological databases

Exploiting and exploring the data issued from heterogeneous sources present a challenge for scientists and decision makers alike. Despite the huge explosion and the availability of geospatial data, the entities that produce them have faced increasing difficulties at the level of harmonization of this information, and especially when it is dealing with structural heterogeneity (schematic). Indeed, structural heterogeneity means that different information systems or rather providers store their data in different structures in their databases. Such variations in the scheme or models of database may limit the interoperability of spatial data. To deal with the problem of schematic heterogeneity, this paper proposes the creation of a Moroccan Model, which is used to map private or native schema (Owner scheme) to MGeoSciML model (Public scheme). Indeed, the access to the information will be based on the international standards of Open Geospatial Consortium (OGC).
