Diagram showing relationships between observation points and the geological description in the GEOFIELD application. The in-house Geofield application makes it possible to manage data from field observations and measurements, rock sampling, and even laboratory analysis. Each geological feature is described by a list of terms from the BRGM registers that are standardized and common to different BRGM applications, are designed to be compatible with European and international standards (GeoSciML and INSPIRE standards).
