Abstract

The invention relates to a method for exploiting (EXP) a subsurface deposit comprising at least one outcrop, the exploitation (EXP) of the deposit is based on a geological model (MOD) formed from a photogrammetry. The method reconstructs the geological outcrops in three dimensions (R3D) from photographs (PHO), and interprets the geological elements thereof, such as the sedimentary surfaces, the geological facies, the fault lines and the fractures, the inclination of the beds, etc. to construct a geological model of the deposit (MOD).
