摘要
大比例尺数字线划图(DLG)数据是铁路勘察设计中重要、使用广泛的基础地理数据,如何实现对DLG数据的高效存储和管理是基础地理信息管理系统建设的重点和难点。研究采用VB.NET和ArcGIS Engine作为平台前端开发工具,利用ArcSDE+Oracle作为后台数据服务器存储管理空间数据,成功开发了DLG数据入库系统,实现了DLG数据的批量、分层、自动、快速入库。
The data of Digital Line Graphics（DLG） are the most important and widely used basic geographic data in the survey and design of railways. How to store and manage the DLG data efficiently was the key and difficult point for the construction of Fundamental Geographic Information Management System. Using VB.NET and ArcGIS Engine as development tools, adopting ArcSDE and Oracle as data server to store and manage spatial data, DLG Data Loading System was developed successfully, DLG data can be bulked, layered and loaded into spatial database automatically and rapidly.
