| Abstract: | The paper analyzes the graphic based on the general situation of the marine baseline buffer and under the proportional line problems.Pointed out that the earth ellipsoid to calculate their complexity,summarizes the technical work in this difficult situation,shortcomings of the popular method of WL & WT in this work,and finally describes the correspon ding map algebra examples. |
