摘要
海陆地理空间信息一体化是当前GIS领域研究的热点和难点。由于海陆地理空间数据存在空间基准不统一、语义表达不一致、多部门分散管理等诸多问题,因此实现海陆地理空间数据整合,实现最大程度的实现地理空间数据共享,是海洋测绘工程急需解决的一个重要问题。测绘基准是表示地理要素在真实世界的空间位置的基准,因此开展海陆地理空间数据一体化的首要任务是建立海陆一体化测绘基准。主要分析了目前我国测绘基准的现状,提出了海陆一体化测绘基准建设的思路,列出了现有测绘基准的变换方法,并对下一步一体化测绘基准建设提出了政策意见。海陆一体化测绘基准建设对维护国家主权、保障国家安全、实施海洋开发具有重要的现实意义和深远的战略意义。
The integration of marine and terrestrial geospatial information is a hot topic and difficult point in GIS research.Due to many problems such as inconsistent spatial benchmarks,inconsistent semantic expressions,and decentralized management of marine and terrestrial geospatial data,the integration of marine and terrestrial geospatial data and the sharing of geospatial data to the maximum extent can be achieved.It is an important problem that needs to be solved urgently in marine surveying and mapping project.Mapping datum is the datum that represents the spatial position of geographical elements in the real world.Therefore,the primary task of land and sea geospatial data integration is to establish the mapping datum of land and sea integration.This paper mainly analyzes the current situation of China’s surveying and mapping benchmarks,puts forward the idea of the integrated surveying and mapping benchmark construction of land and sea,lists the transformation methods of existing surveying and mapping benchmarks,and puts forward policy opinions on the next step of integrated surveying and mapping benchmark construction.It is of great practical and far-reaching strategic significance to safeguard national sovereignty,safeguard national security and carry out marine development to build the marine and land integrated surveying and mapping Benchmark.
