Environmental Information Monitoring System (EIM) Monitoring Stations

The Environmental Information Management System (EIM) is the Department of Ecology's main database for environmental monitoring data. EIM contains records on physical, chemical, and biological analyses and measurements. Supplementary information about the data (metadata) is also stored, including information about environmental studies, monitoring locations, and data quality. Data in EIM is collected by Ecology or on behalf of Ecology by environmental contractors - and by Ecology grant recipients, local governments, and volunteers. EIM Locations is a point feature service representing the monitoring locations from EIM. The locations consist of both surface locations for monitoring air, water, and habitat and wells for monitoring ground water. This feature service queries directly the EIM publication database which is updated nightly from the production transactional database.环境信息管理系统（Environmental Information Management System，简称EIM）是生态部用于环境监测数据的核心数据库。EIM存储有物理、化学与生物分析及检测的相关记录；系统同时存储数据的配套补充信息（元数据，metadata），涵盖环境研究、监测点位及数据质量相关内容。EIM的数据来源包括生态部自行采集的数据、环境承包商代生态部采集的数据，以及生态部资助项目受助方、地方政府与志愿人员提供的数据。EIM点位（EIM Locations）是用于展示EIM中所有监测点位的点要素服务（point feature service）。此类点位涵盖两类：一类是用于监测大气、水体与生境的地表监测点，另一类是用于监测地下水的监测井。该要素服务直接对接EIM发布数据库，该数据库每日夜间由生产事务数据库完成同步更新。
