摘要
根据“只测一次”新理念的基础地理实体数据,能够达到“多级复用”,并实现对现实世界分尺度表达,是目前新型基础测绘与实景三维建设中重点关注的问题。基于基础性、经济性、示范性原则,北京市作为全国率先开展新型基础测绘体系试点与建设的城市,其基础测绘成果的转型升级与高层次应用是一项重要任务。该文以北京市新型基础测绘示范区100㎞^(2)地形图标准化产品试生产为背景,利用地理实体无级综合表达技术,将基础地理实体数据通过定制选取、实体综合、制图派生、适配成图技术处理后,自动派生出1∶500、1∶2000、1∶10000地形图产品。通过分析派生成果的效果与效率,验证了该文生产实践的可靠性,可为全国新型基础测绘体系建设项目的开展提供可借鉴的方法支撑及经验成果。
Based on the new concept of"only measuring once",the basic geographic entity data can achieve"multi-level reuse"and multi-scale representation of the real world,which is the focus of attention in the new fundamental surveying and mapping and three-dimensional(3D)construction.Based on the principles of foundation,economy,and demonstration,Beijing,the first city in China to pilot and construct a new fundamental surveying and mapping system,undertakes the important task of the transformation,upgrading,and high-level application of its fundamental surveying and mapping achievements.Based on the pilot production of a standardized relief map for 100 square kilometers in the Beijing New Fundamental Surveying and Mapping Demonstration Zone,this paper employed the technology of hierarchical comprehensive expression of the geographic entity.The relief maps of 1∶500,1∶2000,and 1∶10000 were derived automatically after the processing of the basic geographic entity data,including customized selection,entity synthesis,mapping derivation,and adaptation mapping techniques.By analyzing the effect and efficiency of the derived results,the reliability of the production practice in this paper was verified,which could provide a reference method and experience for the construction project of the national new fundamental surveying and mapping system.
