基于GIS的黑龙江省公路数据库的设计

Design of Heilongjiang Highway Database based on GIS

使用GIS技术管理具有空间特性的公路已成为公路交通管理的必然趋势。以黑龙江省公路为对象进行数据库设计,提出使用GIS技术实现黑龙江省公路交通数据的可视化管理,分析公路所涉及的各类空间数据和属性数据,并对以公路为主体的各种空间要素进行编码设计,旨在利用实体的编码连接与公路相关的各类数据,以方便程序编写时调用,同时结合公路交通管理中的业务需求,对这些数据进行数据库结构设计。

It is an inevitable trend of traffic management for using GIS technology management of highway with spatial characteristics. A design of the database aiming at the object of Heilongjiang highway is proposed by using GIS technology to realize the highway traffic data visualization management. All kinds of spatial data and attribute data concerning highway are analyzed. The coding of highway various space elements is designed, which tends to make use of the entity code connecting highway related data. Based on the business requirements for the road traffic management, these data are used in the database structure design.
