资源简介：
Environment Agency Control Stations (EACS) or Benchmarks (EABMs) have been created since the 1990s for use as survey control for Environment Agency projects.
Control stations are fixed locations in the country which have been accurately surveyed using GPS / GNSS data. Our control stations are often near Environment Agency structures and they are used as reference heights for many different types of surveys which are carried out near the control stations.
The control stations are graded with different levels of accuracy due to the varied survey techniques that were used in establishing the points. Attribution statement: © Environment Agency copyright and/or database right 2016. All rights reserved.
自20世纪90年代以来，环境署控制站（EACS）或基准点（EABMs）已被创建，用于作为环境署项目的外业控制基准。控制站为国家中的固定位置，已通过GPS / GNSS数据进行精确测量。我们的控制站通常位于环境署结构附近，并作为多种不同类型的外业调查的参考高度。由于在建立这些点时使用的测量技术各异，控制站根据精度等级进行分级。归属声明：© 环境署版权和/或数据库权利2016。版权所有。
