WFD Cycle 1 Site Classifications 2011

For the Water Framework Directive (WFD) water bodies are given classifications based on data collected at monitoring sites. There may be one or more sites per water body. Classification is an important part of the WFD life cycle, it allows the current environmental conditions to be defined. Subsequent classifications indicate if any work carried out is having a positive effect.
Data are collected by field operatives or automated collection methods. These data are passed through models that calculate the classification for a site. These results then form the basis of a water body classification.
Included are much of the supporting data produced by the models, called classification facts.
This data set is extracted from the Environment Agency's Catchment Planning System. Data are available for each year and WFD planning cycle.
Further information is available in a readme file included with the data. Attribution statement: Environment Agency copyright and/or database right 2016. All rights reserved.

本数据集源于水框架指令（WFD）下的水体分类，基于在监测站收集的数据对水体进行分级。每个水体可能包含一个或多个监测站点。分级是水框架指令生命周期中的关键环节，它能够界定当前的环境状况。后续的分级可表明所执行的工作是否产生了积极的影响。数据收集由现场操作员或自动化收集方法完成。这些数据通过模型进行处理，以计算监测站的分类。这些结果构成了水体分类的基础。数据集中还包括了模型生成的许多辅助数据，称为分类事实。本数据集从环境署的流域规划系统中提取，数据涵盖每年的水框架指令规划周期。数据附带的相关信息可在数据包中的readme文件中找到。归属声明：环境署版权及/或数据库权利，2016年。版权所有。
