Information system extraction points (stones and earths)

The information system “Professional Authorities” manages important data of all extraction centres which have been collected by the Geological Service North Rhine-Westphalia in the framework of the authorisation procedure since 1972 after the introduction of the Abgrabungsgesetz (21.11.1972). The database also contains altar excavations as far as they are known. The compilation does not guarantee an actual excavation activity, since only the application documents and the resulting authorisations are covered. The completeness of the presentation depends on the participation of the Geological Service in the subsequent authorisation procedure The attributes of over 8700 extraction sites (as of 01/2016) are managed in FB 21 in an ACCESS database. For the information system of the extraction sites, all geometry data of the mining surfaces were collected in vector form and integrated into “ArcGIS”.信息系统‘专业监管机构（Professional Authorities）’负责管理自1972年《采掘法》（Abgrabungsgesetz，1972年11月21日）施行以来，北莱茵-威斯特伐利亚州地质调查局（Geological Service North Rhine-Westphalia）在审批许可流程框架内收集的全部采掘中心的重要数据。该数据库同时收录所有可查的采石场发掘相关记录，但本汇编并不保证对应发掘活动实际发生，因其仅覆盖申请文件及由此获批的许可文书。信息展示的完整性取决于北莱茵-威斯特伐利亚州地质调查局是否参与后续的审批许可流程。截至2016年1月，共计8700余个采掘点位的属性信息已通过FB 21模块存储于ACCESS数据库中。针对本采掘点位信息系统，所有采矿作业面的几何数据均已以矢量形式采集，并集成至ArcGIS平台。
