【Abstract】 To the requirement of design,some polishing works are needed to be done with topographic map.However,the routine methods can not solve these problems quickly and coveniently that involves the conversion and surveying of elevation system for large-format land map.This article aims to solve those problems from the way of VB and lisp,and gained favorable results in practice. 更多还原
