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.***[Logo Producers BD Sol Hérault](https://www.openig.org/sites/default/files/inline-images/logo_bdsol_herault.png)** 埃罗省农业土壤学（agropaedological）单元制图及配套地质说明：涵盖母岩、岩石群、按重要程度分级的母质、交错或叠置岩层，以及后续地貌过程。**本数据为埃罗省（Hérault Department）土壤数据库的组成部分，该数据库同时包含土壤与风土（terroir）属性地图数据。** 尽管本数据集包含大量土壤相关信息，但严格意义上并非标准土壤数据：未标注科学土壤学名，仅明确了母岩类型。本项目旨在构建具备高度实用价值的农业土壤学数据库。 本数据源自朗格多克-鲁西永（Languedoc-Roussillon）葡萄酒产区潜力区划项目，该项目隶属于1980年至1996年间为优化葡萄品种与风土适配性而推进的州-大区合作计划，以及2000年至2006年间的省域风土认知与价值赋能部门计划。2009年至2011年间，埃罗气候协会（现已并入埃罗省）联合埃罗省农业商会与埃罗省议会，开展了土壤数字化项目，本数据即源自该项目的数字化成果。 埃罗省农业土壤学制图方法自20世纪80年代起，与蒙彼利埃法国国家农业研究院（INRA Montpellier）地质与土壤科学实验室的P. Bonfils与G. Labau教授合作，基于科学依据开发完成。本数据集由埃罗省负责校正与维护，并于2018/2019年由蒙彼利埃大都会（Métropole de Montpellier）针对土壤属性完成部分区域的增补（地质特征与风土相关的增补工作尚未开展）。 **完整性限制：** 本制图未覆盖埃罗省全部市镇，亦未涵盖各市镇的全部辖区范围。因此，未标注的土壤类型即代表对应数据缺失。 **精度限制：** 本制图比例尺为1:10000（即所谓"市镇级"比例尺），不得用于更大比例尺的应用场景。专家建议，请勿将本数据与更大比例尺的地籍图进行叠加。不同**置信度指数（confidence indices）**可用于表达制图边界的不确定性，因此使用本公开数据时需严格遵循其精度限制，谨慎操作。埃罗省及其技术与科学合作方，不对本数据库的偏差及不当使用承担任何责任。更多详细信息请查阅配套文档。 *本数据取自[埃罗省官方数据集（Hérault Data of the Hérault Department）](https://data-herault-occitanie.opendatasoft.com/explore/dataset/bd-sol-terroirs-herault/table/?disjunctive.commune&disjunctive.utn;)目录，为适配地理API接口，现已发布至OPenIG目录中，二者为互补关系。*
