中国地形图查询管理系统设计与实现

Design and realization of China Topographic Map Query and Management System

本文分析了中国地形图的分类规则,研究了图幅网格数据的生成方法,并基于组件式GIS和SQL Server数据库技术,借助Microsoft Visual Studio开发平台设计开发出中国地形图查询管理系统。实现了地形图数据管理、数据导入导出、空间查询、行政区查询、流域查询、新旧图幅号对照等功能,弥补了当前地形图信息查询系统的功能缺陷。

The classification rules of the topographic maps of China are studied herein, and then the data generation method for the subdivisions grid of the map sheet is also studied. Furthermore, the China Topographic Map Query and Management System is established with the Microsoft Visual Studio based on COM GIS, SQL Server; which realizes the functions such as topographic da- ta management, data input/output, spatial query, administrative region inquiry, watershed query, contrast between the new and the old map sheet numbers, etc. Therefore, the inadequacies of the current topographic map information query systems are effectively made up.
