The first version of OLPAC arises from research works of an Internation Program in Ecuador. The prototype took the form of a GIS script developed with the Research Institute for Development (RID).
Thanks to research works and applications on concrete cases, the existing method has been enriched with new bases: integration of a semi-dynamical model for the calculation of hydrogeological balance in soil.
Beginning of a partnership with the FOEN (Swiss Federal Office for the Environment) and the Vaud Canton. Design of a new product: Olpac Consult.
Setting the first test site for the realtime monitoring in the Val d'Illiez (Switzerland) in partnership with the FOEN and the Valais Canton. Development of new algorithms for the management of the landslides flow, with the help of the FOEN Innovation services.
After two unfavourable meteorological conditions and the forecast of an import quantity of rain, OLPAC Web sent an alert. Multiple landslides occurred after the forecast date provided by the OLPAC alert.
