BD Sol – Properties – Hérault

Mapping of the agro-pedological units of the department of Hérault and their properties: rock, position, depth, texture, pierrosity, useful reserve, pH. **This data is a component of the soil database of the Department of Herault, which also includes the cartographic data of [geology](https://www.herault-data.fr/explore/dataset/bd-sol-geologie-herault/) and [terroirs.](−) ** Although these data provide a lot of soil information, they do not constitute soil data per se: no scientific soil name is given, only mother rocks are specified. The aim here is to establish an agro-pedological database with a strong practical purpose. The data are derived from the programmes of zoning of the wine potential of Languedoc-Roussillon, as part of the State-Region plans for a better adaptation of grape variety between 1980 and 1996 and the departmental programme of knowledge and valorisation of terroirs between 2000 and 2006. The data were digitised as part of the Soil Digitalisation Program of the Association Climatologique de l’Hérault (now integrated into the Department) conducted in partnership with the Chambre d’Agriculture de l’Hérault and the Conseil Départemental de l’Hérault from 2009 to 2011. The methodology of agro-paedological mapping of the department of Hérault 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 is currently corrected and maintained by the Department of Hérault. It was also completed on its territory by the Métropole de Montpellier in 2018/2019. **Completeness Limits**: The cartography ** does not cover all the Heraultese communes, nor the total area of each municipality**. As a result, **uninvented soil means a lack of data.** **Mapping precision limits**: The mapping of soil properties ** is on a scale of 1/10 000th** (so-called “communal” scale). They must not be used on a higher scale. Thus, superposition with cadastral plans made on larger scales is not recommended by experts. Different ** confidence indices** allow to translate the uncertainty of the cartographic limits. Some attributes such as depth or texture are estimates made from field surveys. In environmental studies, these soil data alone are not sufficient to understand a territory. They need to be crossed with other types of data such as climatology. **The data made available should therefore be used with caution according to the accuracy limits**. The department of Hérault and its technical and scientific partners cannot be held responsible for inaccuracies in the databases and for inappropriate uses of the databases.

Bonfils与G. Labau教授团队基于科学依据开发。目前该数据库由埃罗省政府进行修正与维护，并于2018年至2019年由蒙彼利埃都会区（Métropole de Montpellier）在其辖区内完成数据补充。 **完整性限制**： 本制图未覆盖埃罗省全部公社，亦未涵盖各公社的全域范围。因此，未被测绘的区域意味着缺乏对应数据。 **制图精度限制**： 土壤属性制图的比例尺为1/10000（即所谓“公社级”比例尺），不得在更大比例尺场景中使用。因此，专家不建议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）**可用于表征制图边界的不确定性。部分属性如土层深度与土壤质地为基于野外调查的估算值。在环境研究中，仅依靠此类土壤数据不足以完整认知某一区域，需与气候学等其他类型数据交叉分析。 **因此，使用本公开数据时需严格遵循其精度限制要求**。埃罗省及其技术与科学合作方不对数据库的不准确之处及不当使用承担责任。 本数据集可通过以下链接进行可视化查看：[区域制图](https://mviewer.openig.org/?config=/maps/openig/donnees-sols-en-occitanie.xml) 更多信息请参阅配套文档。
