基于DLG数据制作省级基础地理实体的方法

Production Method for Creating Provincial-Level Fundamental Geographical Entities Based on DLG Data

摘要: 广东省新型基础测绘体系建设正在稳步推进，其中省级基础地理实体制作与建库是重要任务之一。本文根据新型基础测绘与实景三维中国系列技术文件，总结了一种基于DLG数据制作省级基础地理实体的生产方法。此方法已应用于广东省省级基础地理实体生产，经生产验证，其生产流程和技术路线可行，可为其他地区省级基础地理实体生产提供技术参考。

Abstract: The construction of Guangdong Province’s new fundamental surveying and mapping system has entered its steady implementation phase, with the development and database construction of provincial-level fundamental geographical entities serving as one of its key tasks. Drawing upon the series of technical specifications for New Fundamental Surveying and Mapping and the 3D Real Scene China initiative, this paper summarizes a methodology for creating provincial fundamental geographical entities based on DLG data. This approach has been successfully applied to the production of provincial-level fundamental geographical entities in Guangdong Province. As demonstrated in practice, its production workflow and technical roadmap are feasible and can serve as a technical reference for similar provincial-level basic geographic entity production in other regions.
