| Abstract: | Trigonometric Leveling is an available method of passing the elevation while falling across the rivers, lakes and gorges , where we can＇ t transfer the altitude step by step because of the obstacle. It＇ s also able to be used in cross-sea elevation. When the distance beyond the measuring instrument＇ s capability, GPS surveying could satisfy the precision needs of the long distance surveying over the sea. A set of high precision observing methods and actualizing projects of the cross-sea elevation are put forward based on the trigonometric leveling with the leveling measurement and GPS positioning. Using the surveying data of our country＇ s twelve islands, to analyze the feasibility, precision and validity of the observing methods and actualizing projects synthetically, some useful advice and notice are also given in the end. |
