株洲市多尺度地形图智能化缩编系统设计与实现

摘要

Various scales topographic information data is an important part of the construction of basic geographic information database.For adapt to the development of information construction and convenient planning approval,the production various scale topographic maps became Realistic Choice.Taking Zhuzhou City 1:500 fundamental topographic map database downsizing as 1:1000,1:2000 and 1:5000,1:10000 series scale topographic map as an example,it formulated self adapted rules database, and output corresponding scale topographic map according to foundation topographic map information based on database management.This method of intelligent downsizing based on spatial database provides a new thinking for topographic map.%各种比例尺地形信息数据是基础地理信息数据库建设的重要内容.为了适应信息化建设的发展,保障规划审批的方便快捷,制作各种比例尺地形图是现实的必然选择.据此,以株洲市 1:500 基础地形图数据库缩编为1:1000、1:2000、1:5000、1:10000 系列比例尺地形图为例,制定自适应规则库,利用数据库管理的基础地形图信息,按需输出相应比例尺地形图.此种基于空间数据库的智能化缩编方法为地形图缩编提供了一种新思路.
