基于LISP的地形图居民地要素入库预处理方法研究

The Research on Resident Element of Topographic Map Storage Preprocessing Method Based on LISP

城市地形图数据库建设是数字城市建设的基础,其中地形图各要素的入库前预处理是整个项目进展的重要环节,直接关系到整个城市数据库的质量。本文以福建省某市1∶500数字地形图数据库建设项目为例,针对传统居民地要素预处理方法费时耗力的特点,提出了基于LISP的处理方法。实践证明,该方法提高了数据库建设中居民地要素入库前预处理的效率。

City topographic map database construction is the foundation of the construction of digital city,and topographic maps of various elements of the storage pretreatment is the progress of the project the important link,it directly affected the entire city database quality.In this paper,a city of Fujian province 1:500 digital topographic map database construction project as an example,in view of the traditional resident element preprocessing method is time-consuming and energy features,puts forward a new processing method based on LISP.Practice has proved,this method can improve the efficiency of residential feature pretreatment.
