| Abstract: | In accordance with the characteristics of Geodetic height system and normal height system ,the normal height system of Wacun Hydropower Station reservoir area was set up based on the data of GNSS plane control net-work and Guangxi quasi-geoid model refinement. The author analyzed the height accuracy,discussed the problem existing in setting up reservoir area normal height system by use of Guangxi quasi-geoid model refinement. With ref-erence to traditional annexed leveling line,the author put forward a method for the evaluation of grade IV leveling measurement accuracy with GNSS height fitting technology. |
