摘要:

边界定界与管理事关国家主权与安全。以定性分析和模拟推算为主的传统技术手段,难以有效地支撑精确高效定界和动态维护管理。针对这一重大应用需求,我有关部门启动了专项建设工程,以超媒体数据建模为基础、精准化定界分析为核心、集成化信息服务为依托、建成了中国“数字国界”,为国界划界、勘界、联检及管理提供了全新技术手段,有效提升了外交国界工作的整体技术水平。

Abstract:

China has the world’s longest land boundary line with the length of over 22,000 kilometers and borders 14 countries. The state boundary and border regions are characterized by extreme diversity in terms of geology, topology as well as culture, which makes the boundary delimitation, demarcation and maintenance very complicated and challenging. This paper gives a brief introduction of the research and development on the state digital boundary. A comprehensive spatial boundary database had been set up by spatial integration of multi-media, multi-temporal and multi scale boundary documents and data. Special information processing and analysis systems for delimitation and demarcation had been successfully developed by combing boundary legal knowledge and digital terrain analysis. Information systems for regular and daily boundary maintenance were also developed and now in operational use.

Key words: digital boundary, object-oriented data modeling, delimitation and demarcation, information service
