区域似大地水准面精化成果检验方法探讨

Study on inspection method for region quasi-geoid determination results

利用GNSS技术可以简单快速地测定厘米级的大地高,使用GNSS测定的大地高结合高精度的大地水准面精化模型,可以快速准确地确定待测点的海拔高程。随着各省、市似大地水准面精化模型的建设,似大地水准面成果正在改变着测绘的方式,推动测绘工作快速高效地应用于国民经济建设。目前我国缺少区域似大地水准面成果检验的相关规范或技术规程,如何对似大地水准面成果进行检验,缺乏统一的技术依据。本文从检验内容与方法方面探讨区域似大地水准面精化成果检验的相关问题,提出内容、方法的同时并应用于实际检验工作,为区域似大地水准面精化检验工作提供参考。

The geodetic height can be surveyed quickly with the precision of centimeter level by using GNSS technology. Combining it with high precision quasi-geoid determination results,the elevation of the point we wanted can be obtained quickly and accurately. As more and more quasi-geoid determination results are constructed in many provinces and cities,the quasi-geoid results make the surveying and mapping work quickly and efficiently. So far,we lack of test specifications or technical specifications on how to test and inspect regional quasi-geoid results in China. In this article,we discuss the content and method in the work of quasi-geoid results inspection and put it into practice.
