## **摘要**

本数据集由生物区域评估计划从《Hydstra地下水测量更新 - 新南威尔士州水务办公室，2013年11月》衍生而来。源数据集在本元数据声明的谱系字段中标识，生成该衍生数据集的过程在本元数据声明的历史字段中描述。

本数据集以地理信息系统（GIS）格式呈现Hydstra原始测量数据（HYDMEAS）的表格记录（存储于Hydstra软件平台中），以便进行解读与分析。

对本数据集的分析包括提取数据以确定当前监测井的位置和状态：

HYDMEAS - 显示地下水位的原始表格数据库文件（dbf格式）

HYDMEAS_XY_all - 以GIS shapefile格式呈现所有原始表格数据

HYDMEAS_unique_bores - 为每个唯一监测井站点ID显示一条记录

HYDMEAS_2008 - 2008年及以后的所有HYDMEAS数据

HYDMEAS_2008to2013_multiple_reading - 2008年至2013年间监测次数≥2次的所有HYDMEAS数据，用于估算地下水位监测井

国家地下水信息系统（NGIS）数据被提供作为HYDMEAS监测估算结果的对比参考。

Hydstra是由KISTERS Pty Ltd开发的水资源时间序列数据管理系统。

## **目的**

提供新南威尔士州地下水位监测状态与读数的空间分布。

## **数据集历史**

HYDMEAS - 原始表格数据

HYDMEAS_XY_all - 以GIS格式呈现所有原始表格数据 - 基于纬度和经度属性在ArcGIS中以XY形式显示，并导出为点shapefile格式

HYDMEAS_unique_bores - 为每个唯一监测井ID显示一条记录 - 基于STATION字段对HYDMEAS_XY_all进行融合

HYDMEAS_2008 - 2008年及以后的所有HYDMEAS数据 - 基于DATE字段筛选

HYDMEAS_2008to2013_multiple_reading - 2008年至2013年间监测次数≥2次的所有HYDMEAS数据（用于估算地下水位监测井） - 基于STATION字段对HYDMEAS_2008数据集进行融合，并添加计数字段，仅保留计数≥2的监测井
