| Abstract: | To hold multiform laying off methods of turning point is very important to work efficiency in vertical and cross section survey. Based on this, this paper introduces basic measuring method of turning points; sums the principle and method of turning point laying off with option quadrangle and triangle; brings forward the principle and method of laying off of turning point with Euclidean geometry principle under existing control point and under complicated topographic condition. Application of CAD map technique is discussed in process of laying off of turning point |
