Building on 50 years of geomodelling: walking a tightrope between tradition and clean slate

Abstract : Geological surveys are facing the transition from systematic 2D mapping of national territories to more versatile – possibly cross-border – 3D models. BRGM has produced geological models for several decades in a project driven approach implying specific goals, hypotheses, scales, modeling tools... In such an approach, a few experts’ choices may constrain the final deliverable and hamper interdisciplinary contributions. Our talk will detail practical challenges that is currently facing BRGM in redesigning its set of existing modelling tools into an open modeling platform based on modular software components that will ideally combine both proven legacy and newer methodologies to overcome existing tools limitations and promote true interdisciplinary experience. Starting from the observation that several tools share common concepts, a first step is to clearly identify and generalize these underlying concepts (e.g. geological pile/architecture to express relations between geological interfaces). Nevertheless, there is still a considerable gap between the geologist’s dream tool and the modeling experience that have been offering geological software for the last twenty years – mainly consisting in popularizing the “implicit” modeling approach. Though some fields of research are promising, as are many technological devices, the feeling is that we still need a breakthrough that would change the daily life of geological model producers and represent a clear alternative to old monolithic software. As a survey, our position, either individually or more collectively (e.g., European geological surveys) still needs to be found between two major trends: the replacement of proprietary commercial suites by web-service based cloud platforms and the rise of many open-source initiatives. Though promising, the latter does not benefit from a mature structured global community support yet, as it can exists in other communities (e.g., for GIS), which would make us take the next step.
