| Abstract: | We study the error sources and precision of precise trigonometric leveling with ATR（automatic target recognition）. Based on the application of Fujin Dam in Fujiang, we analyzed the actual precision of trigonometric leveling with ATR of TCA2003 total station and its feasibility of substitution for second-order leveling. |
