CUI You-zhen HAN Guang-shun LI Wen-jie (1.Beijing Polytechnic College,Beijing 100042,China;2.Beijing Institute of Surveying and Mapping,Beijing 100038,China)  
According to the refined error analysis,the optimum graph can be obtained after analysis the geometric drawing which is linear-angular resection.Then the risk area of the linear-angular resection can be obtained by point to point error isoneph delineation.In addition,a method of graph modification and optimization can be reached according to practical situation in field engineering.
