Geotechnical investigation site

The term “geotechnical investigation site” refers to locations where geotechnical (surveys and instrumentation) and geophysical data are available. This data includes:

Geotechnical investigation sites (site_inv_geotech_p): Geotechnical surveys produced by or for the Ministry from the 1990s, from the active database of the Directorate of Geotechnics and Geology (DGG). Data is added as it is validated. This file is accompanied by a Stratigraphic Characteristics table (site_inv_geotech _STRATI.csv). This contains stratigraphic information for the majority of sites and can be linked to the location file using the “NO_UNIQUE” primary key.

BDG geotechnical investigation sites (site_inv_geotech_bdg_p): Geotechnical drilling and drilling from an “inactive” database entrusted to the DGG by the Ministry of Natural Resources and Wildlife (MRNF), since the mid-1980s. These are drilling and survey data compiled by the MRNF in the 70s and 80s for “predictive” or “geotechnical soil suitability” mapping campaigns. As it is an inactive database (not evolving), there are no updates to be expected. This third party metadata element was translated using an automated translation tool (Amazon Translate).
