Research on Improvement and Maintenance Strategy of Provincial Modern Surveying and Mapping Datum System
摘要
Abstract
This paper presents a systematic investigation into the improvement and maintenance of provincial modern surveying and mapping datum system.Against the backdrop of rapidly evolving spatiotemporal information technologies and the shift to intelligent surveying and mapping,the study identifies the key technologies required for constructing a high-precision datum framework.A complete set of systematic improvement and maintenance strategies is proposed covering five core components:the provincial satellite navigation and positioning service system,horizontal control network,vertical control network,gravity control network,and quasi-geoid modeling.Together these components form an integrated solution for the construction of modern spatiotemporal infrastructure.The results show that province-wide datum modernization should follow an integrated technical roadmap under a coordinated governance mechanism,which ensures the framework is scientifically sound,technologically advanced,and operationally reliable,while meeting the urgent demand for accurate,real-time,and continuously available positioning services to support socioeconomic development.The conclusions of this study provide a valuable reference for other provinces carrying out continuous improvement and maintenance of their surveying and mapping datum systems.关键词
