Data Dealing and Quality Analysing of the Trigonometric Leveling Over the Sea
Wu Wei · Hydrographic Surveying and Charting · 2012
Based on introducing the general situation of the four surveying areas of elevation-passing,all of which have finished the actual observation,and a new method of evaluating the data quality is proposed.After evaluating and calculating,the result indicates that:the mean square error of the four areas could reach the level of the second class leveling;only about 50 percent of the original observing data satisfy the requirements of the second class leveling;90 percent could meet the third class leveling needs.
