Open Session - SWISS GEOSCIENCE MEETINGs

Main results from this case study are pointed out and discussed:
• Realization of the first synthetic geotype map of the canton of Vaud (figure 1) and associated map of foundation soils;
• Geological consistency between maps realised by different authors;
• Transparency and traceability of the successive data processing operations, from raw geological information to end products;
• Valorisation of the geological information to be combined in the future to other territorial information through GIS (e.g.
digital elevation models (DEMs), comprehensive development area maps, geological cadastre).
• GIS capacity for easy re-actualization of maps.
Adaptations of this method to other geological environments or for other engineering projects (natural hazards, groundwater
protection) are ongoing developments.
