摘要
区域精化似大地水准面在全国多个地区已经建立,同时也得到了广泛应用。在应用过程中,大大提高了测绘工作效率,缩短了生产周期,减轻了外业作业强度。随着区域CORS系统的建立及GNSS(全球导航卫星系统)的广泛应用,区域精化似大地水准面的应用前景更加广泛。但同时我们也应该掌握如何让似大地水准面成果的应用符合现行的《规范》要求,保障测绘成果的准确性,避免粗差。
The local refined Quasi-Geoid has been constructed in several regions and widely applied.During the applying process,it improved the working efficiency of surveying and mapping,shortened the production period,and reduced the working load of fieldwork.With the establishing of regional CORS system and the widely applying of GNSS(Global Navigation Satellite Systems),the application of local refined Quasi-Geoid will be wider.Meanwhile,the application of Quasi-Geoid results should accord with the requirements of existed specification to ensure the accuracy of surveying and mapping results,and avoid coarse error.
