The GeoFrance 3D programme, which combines geological and geophysical information to produce reliable three‐dimensional models, is devoted to studying crustal and lithospheric structures in France and neighboring countries. In addition to the GeoFrance 3D regional projects, illustrated by the results of the Alps or the Massif Central projects, the Million project compiles geological and geophysical data and insures their quality in order to valorize them by modeling at the million scale. By applying data analysis and validation methodology to gravity data compilation, we discovered that the Bouguer anomaly map only provides a discriminating insight of crustal structures if uncertainties of gravity measurements, sampling heterogeneities, and processing errors are known.
