地形图高程点高程自动提取的程序设计与实现

摘要

出于提取高程数据的需要,针对地形图中高程点及其标注一一对应的特点,提出了批量提取高程点高程的自动提取算法,实现了一次完成所有高程点高程值赋值,并给出了核心实现代码。%To extract elevation data,for the characteristic that one elevation point corresponding to one mark,a method is Proposed that automatically extract elevation of elevation point in this paper,the author achieve completely assignment of all the elevation point elevation value and list the core implementation code.
