[Method] The specific calculation was proposed and then verified with examples. Its calculation results were then compared with the exact consequence which has been calculated by classic calculus method already. [Result] The triangulation method has achieved good results in the calculation of ellipse area. And it can meet the requirements of cadastral area calculation for precision. [Conclusion] The application of triangulation method to the measurement of land area has broad prospect in the digital calculation of land area.
