【摘要】 针对海洋测绘基准的特点,本文讨论陆海空间基准现状及存在问题:提出了直接采用CORS网络构建和维持陆海一体化空间基准,创建了基于CORS的陆海一体化现代高精度三维测绘基准模型,初步构建了连云港海域基准服务CORS工作基点网,并尝试建立新一代国家三维地心大地坐标系统(CGCS2000)空间框架结构体系。更多还原

【Abstract】 Aiming at the characteristics of the hydrograpic surveying and charting datum,the status and problems were discussed for the Space Datum of Land & Sea.The author is brought forward the direct use of CORS network to build and maintain the integration of land and ocean space datum.The modern high-precise three-dimensional Integrative Land & sea Model of the surveying and mapping datum was oreated.The CORS service point network was initially built in Lianyungang sea area.To achieve national unity CGCS2000 geocentric geodetic coordinate system,dynamic three-dimensional space frame structure was established.更多还原
