iREGIS stands for REgionaal Geohydrologisch InformatieSysteem, which is the National hydro-geological model for the Netherlands. Version II.1 is an extension and revision of the hydro-geological model version II.0 (REGIS II). REGIS has been developed by TNO, the Geological Survey of the Netherlands in cooperation with RIZA (the national water office) and the Provincial authorities. The hydro-geological model is a digital model of the upper part of the Dutch subsurface to a depth of approximately 500 meters. Using ESRI grids and shapefiles, the model shows the depth, thickness and hydraulic properties of hydro-geological units as well as the location of faults. A hydro-geological unit is a unit defined using texture, structure and soil type having (more or less) uniform hydrogeological properties bounded by facies-layers, erosion boundaries and faults. The hydrogeological model is based on the Digital Geological Model (DGM) and the shallow subsurface lithostratigraphical Nomenclature version 1.0 which is available through www.dinoloket.nl

This map shows the sediments close to the surface (or sea bottom), down to a depth of about 5 meters. This map is based on existing maps of the former Rijks Geologische Dienst and, where necessary, supplemented by unpublished data. The sediments are classified according to the new lithostratigraphical legend used by TNO since 1997. This classification is based on lithological and seismological properties, and on stratigraphic position and origin. The age of the sediments is not taken into account in this classification.

BSS is the French Boreholes database containing information from about 700 000 boreholes, accompanied by 2 000 000 pages of technical documentation. BSS contains raw information about geology and the technical details of the procedures used to drill the boreholes. This information is provided by operators under the terms of French law (Code Minier art. 131 à 136).
