新疆国家地下水监测站高程测量质量控制探讨

Discussion on the Quality Control of Elevation Survey of Xinjiang National Groundwater Monitoring Stations

新疆地下水监测工程的430个地下水监测站分布于自治区下辖14个地区,采用水准测量等常规方式难以完成监测站高程及平面坐标测量。本文提出建立新疆似大地水准面模型,采用XJ-CORS为主、常规方法为辅的测量方法,通过采用地下水监测站与CORS基准站距离控制、外业测量操作流程控制、数据质量控制、观测质量评价等一系列技术手段,完成了监测站高程及平面坐标测量,保证了观测质量。

The 430 groundwater monitoring stations in Xinjiang are distributed in 14 areas. It is difficult to com-plete the elevation and plane coordinate measurement of the monitoring stations by conventional me-thods, such as leveling. This paper proposes to establish a quasi-geoid model in Xinjiang, using XJ-CORS and supplemented by conventional methods, through a series of technical means, such as distance control between groundwater monitoring stations and CORS reference stations, field measurement operation process control, data quality control, observation quality evaluation, etc. to complete the elevation and plane coordinate measurement of monitoring stations, and guarantee the quality of the results.
