摘要/Abstract

摘要：

保持基础地理信息的现势性是我国基础测绘工作的重要使命。为此,国家测绘地理信息局于2012年启动了国家基础地理信息数据库动态更新工程,对我国1:5万、1:25万、1:100万基础地理信息数据库进行持续快速更新,每年更新一次、发布一版。本文介绍了动态更新的总体技术思路,阐述了基础数据库动态更新、派生数据库联动更新、多时态数据库管理服务等主体技术方法,并介绍了主要技术特点和工程应用效果。

关键词: 基础地理信息, 数据库, 动态更新, 联动更新

Abstract:

One of the most important missions of fundamental surveying and mapping work is to keep the fundamental geographic information fresh. In this respect, National Administration of Surveying, Mapping and Geoinformation has launched the project of dynamic updating of national fundamental geographic information database since 2012, which aims to update 1:50 000, 1:250 000 and 1:1 000 000 national fundamental geographic information database continuously and quickly, by updating and publishing once a year. This paper introduces the general technical thinking of dynamic updating, states main technical methods, such as dynamic updating of fundamental database, linkage updating of derived databases, and multi-tense database management and service and so on, and finally introduces main technical characteristics and engineering applications.

Key words: fundamental geographic information, database, dynamic updating, linkage updating
