Abstract: | [Objective] To test the applicability of triangulation method,which has always been used in the microcosmic field,in the macroscopic region,so as to apply it to the calculation of cadastral area.[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. |
