BD Sol — Geology — Hérault

[Logo Producers BD Sol Hérault](https://www.openig.org/sites/default/files/inline-images/logo_bdsol_herault.png) Cartography of the agropaedological units of the department of Hérault with their geological description: mother rock, rock family, parent materials according to their degree of importance, alternating or superposition rocks, geomorphological processes followed. **This data is a component of the Hérault Department’s soil database, which also includes map data of soil and terroir properties.** Although these data provide a lot of soil information, they do not constitute soil data strictly speaking: no scientific soil names are indicated, only the mother rocks are specified. The objective here is the creation of an agropaedological database with a strong practical purpose. The data are derived from the programmes of zoning the wine potential of Languedoc-Roussillon, within the framework of the State-Region plans for a better adaptation of the grape variety terroirs between 1980 and 1996 and the departmental programme of knowledge and valorisation of terroirs between 2000 and 2006. The data was digitised as part of the Soil Digitisation Program of the Hérault Climate Association (now integrated into the Department) conducted in partnership with the Hérault Chamber of Agriculture and the Hérault Departmental Council from 2009 to 2011. The agropaedological mapping methodology of the Hérault department was developed on a scientific basis in collaboration with Professors P. Bonfils and G. Labau of the Laboratory of Geology and Soil Science of INRA Montpellier, from the 1980s. The base has been corrected and maintained by the Hérault Department. **It was also partially completed in its territory by the Métropole de Montpellier in 2018/2019 on the properties of the soils (complement not yet carried out on geological characteristics and terroirs).** **Limits of completeness:** The mapping does not cover all the municipalities of Herault, nor the total area of each municipality. As a result, an uninvented soil means a lack of data. **Map accuracy limits:** Mapping is at 1/10000th scale (so-called “communal” scale). They shall not be used on a higher scale. Thus, superposition with cadastral plans made on larger scales is not recommended by experts. Different **confidence indices** make it possible to translate the uncertainty of cartographic boundaries. The data made available must therefore be used with caution according to the accuracy limits. The Hérault department and its technical and scientific partners cannot be held responsible for inaccuracies in the databases and for inappropriate uses of the said databases.

It is published on the OPenIG catalogue in order to have a Geographic API. This approach is therefore complementary.*
