WATER QUALITY STATION: BIOLOGICAL STATUS 2007-2008

Works of type “Station quality watercourse” originating from the reference of the structures of Agence Artois-Picardie. The “state” values are those measured for the 2007-08 biological status (Order 2010). The repository of the Agency’s works.The work corresponds to any artificial entity (drilling, factory, lock), natural (source) or virtual (place of sampling in a watercourse), geographically located and which performs at least one water-related function within the meaning of activities of the Agency. Some works have legal personality (factory, operation agricultural). Since the structure can perform several functions with respect to the water domain, it is described by a generic entity containing the data common to all works and by entities girls corresponding to the various functions performed by the work. Example: One ‘groundwater Access Point’ type structure can be used for: — capture water (capture) – measure the height of the tablecloth (piezometer) – analyse the quality of the tablecloth (quality measurement station)本数据集收录源自阿尔图瓦-皮卡第水环境管理局（Agence Artois-Picardie）结构参考资料的河道水质监测站（Station quality watercourse）类实体。其中“状态”指标值取自2007-2008年度的生物状态监测数据（依据2010年政令）。 本机构的实体数据集涵盖各类实体：包括人工实体（钻井、厂房、船闸）、自然实体（水源）以及虚拟实体（河道采样点），所有实体均具备地理坐标，且至少承担一项符合该机构业务范畴的涉水职能。 部分实体具备法人资格，例如厂房、农业运营设施。 由于单个实体可承担多项涉水职能，因此数据集采用两类实体进行描述：一类为通用实体，存储所有实体共有的基础数据；另一类为子实体，分别对应实体所承担的各项职能。 示例：某“地下水取水点”类实体可承担以下职能： — 取水（取水功能） — 监测地下水位（测压管功能） — 分析地下水水质（水质监测站功能）
