BD Sol — Dynamic Management of Agricultural Potentialities (GDPA) — Hérault

[Logo Producers BD Sol Hérault](https://www.openig.org/sites/default/files/inline-images/logo_bdsol_herault.png) Agricultural potentials represent the capacity of a soil to accommodate crop production according to soil climatic conditions. These potentials can also be managed by taking into account other parameters (e.g. irrigation networks, socio-economic data, land...). The GDPA tool is based on the study of three soil cultural potentials: field crops, quantitative viticulture (PGI base) and market gardening. Synthesis of the three, the global cultural potential makes it possible to understand the cultural diversification capacity of a soil. Thus, the soils most conducive to diversification (strong global potential) allow the development of a large number of crops. The GDPA decision support tool was established in partnership with the Association Climatologique de l’Hérault (now integrated into the Department), the Hérault Department, the Hérault Chamber of Agriculture and INRAE in 2012/2013. It results from the analysis and processing of agropaedological data from the soil database, established and digitised in 2011. The tool is currently maintained by the Hérault Department. In particular, it has been updated following a work to complement the soil database carried out by the Métropole de Montpellier in 2018/2019. **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, no conclusion as to the potential of that soil can be inferred from it. **Map accuracy limits:** The mapping of crop potentials is at a scale of 1/10,000th (so-called “communal” 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) 农业潜力指的是土壤依据其气候条件适配作物生产的能力。此类潜力亦可通过纳入其他参数（如灌溉网络、社会经济数据、土地利用等）进行调控。GDPA工具基于对三类土壤种植潜力的研究：大田作物、定量葡萄栽培（受保护地理标志（PGI）基准）以及商品园艺。三类潜力的综合即全球种植潜力，可用于表征土壤的种植多样化能力。因此，最利于种植多样化（全球潜力较高）的土壤可适配大量作物的种植。 该GDPA决策支持工具于2012至2013年间，由埃罗省气候协会（现已并入埃罗省相关部门）、埃罗省、埃罗省农业商会以及法国国家农业食品与环境研究院（INRAE）联合开发。其依托2011年建立并数字化的土壤数据库中的农业土壤学数据分析与处理工作而来。目前该工具由埃罗省负责维护，尤为重要的是，2018至2019年间蒙彼利埃都会区对土壤数据库进行了增补工作，工具也随之完成更新。 **完整性局限：** 本次制图未覆盖埃罗省全部市镇，亦未涵盖各市镇的全部区域。因此，若某块土壤未被纳入制图范围，则代表该区域缺乏相关数据，无法据此推断该土壤的种植潜力。 **制图精度局限：** 作物潜力制图的比例尺为1:10000（即所谓“市镇级”比例尺）。因此专家建议，勿将该图与更大比例尺的地籍图进行叠加。不同的**置信指数（confidence indices）**可用于表征制图边界的不确定性。因此，需依据上述精度局限谨慎使用公开获取的数据集。 埃罗省及其技术与科学合作方不对数据库中的不准确之处，以及对该数据库的不当使用承担相关责任。如需更多信息，请查阅相关文档。 *本数据集源自【埃罗省数据目录（Hérault Data of the Hérault Department）】[https://data-herault-occitanie.opendatasoft.com/explore/dataset/bd-sol-terroirs-herault/table/?disjunctive.commune&disjunctive.utn;]，并在OpenIG目录中发布以提供地理信息应用程序编程接口（API）。该发布方式属于补充性的数据发布渠道。*
