Map Viewing Service (WMS) of the data batch: DDT 48 — COMMUNAL MAP OF ISPAGNAC

This CNIG data standard concerns communal map documents (CCs). This data standard provides a technical framework describing in detail how to dematerialise these town planning documents in a spatial database that can be used by a GIS tool and interoperable. This standard of data covers both the graphical plans of sectors and the information overlaying them. This CNIG data standard was developed on the basis of the specifications for the dematerialisation of planning documents created in 2012 by the CNIG, itself based on the consolidated version of the urban planning code dated 16 March 2012. The recommendations of these two documents are consistent even if their purpose is not the same. The CNIG data standard provides definitions and a structure for organising and storing spatial data from communal maps in an infrastructure, while the CNIG specifications are used to frame the digitisation of these data. The ‘Data Structure’ section presented in this CNIG standard provides additional recommendations for the storage of data files. These are specific choices for the common data infrastructure of the ministries responsible for agriculture and sustainable development, which do not apply outside their context.本CNIG数据标准面向市镇地图文档（Communal Map Documents，CCs）。本标准提供一套技术框架，详细阐明如何将此类城镇规划文档数字化并存储于可被地理信息系统（Geographic Information System，GIS）工具调用且具备互操作性的空间数据库中。该数据标准既涵盖街区图形规划图，也包含图面叠加的关联信息。本CNIG数据标准以CNIG于2012年制定的《规划文档数字化规范》为基础开发，而该规范本身则依据2012年3月16日发布的整合版《城市规划法典》制定。尽管两份文件的制定目标存在差异，但其提出的建议保持一致。CNIG数据标准旨在为市镇地图空间数据的组织与存储提供统一的定义与架构，而CNIG规范则用于界定此类数据的数字化实施流程。本CNIG标准中的“数据结构”章节针对数据文件存储提供了额外的补充建议。此类设置仅适用于法国农业与可持续发展部所属的公共数据基础设施，超出该应用场景则不具备适用性。
