介绍了 GIS发展及应用情况 ,提出在高速公路数据库系统设计中引入 GIS的思想 ,直观显示地理数据 ,建立数据库与载有地理信息的电子地图之间的双向联系 ,实现地图与数据库的双向查询 ,解决传统的数据库在描述高速公路信息时累赘、呆板、数据描述不完全等缺点 ,建立地图式数据管理系统的设计思路。其基本的设计思想已通过桌面地图信息系统开发平台 Mapinfo 4.5得到实现
This paper introduces the development and application of GIS, puts forward the idea of introducing GIS into the design of expressway database system, displays the geographical data visually, establishes the two-way relationship between the database and the electronic map containing the geographic information, realizes the bidirectional query between the map and the database, To solve the traditional database in the description of highway information cumbersome, rigid, incomplete description of the data shortcomings, the establishment of map data management system design ideas. Its basic design ideas have been achieved through Mapinfo 4.5, a desktop map information system development platform
