Abstract
The aim of this work is to facilitate access to geological data coming from distributed data sources and the information (metadata) related to these data. For that purpose, a spatial data infrastructure (SDI) prototype has been established which comprises a geoportal that provides access to a geological Catalogue through Catalogue Service for the Web (CSW) in order to get the metadata that describes the data as well as the available services as the WMS (Web Map Service) view and Web Feature Service (WFS) download services, which aims to be compliant with the Open Geospatial Consortium (OGC) standards rules. Indeed, the establishment of spatial data infrastructure that has been elaborated in accordance with internationally recognized standards allows the exploration and sharing of geological data information, and will also allow researchers and professionals to spend more time in the analysis and the discovery of these data. This work can be used as a model for other fields in geoscience such as geophysics and hydrology or other close fields.
