探讨了建立新一代中国似大地水准面模型中的陆海大地水准面的拼接,分析了拼按差产生的原因,阐述了无缝拼接需要遵循的原则,提出了基于拟合拼接法的拼接方案。
The question of the merge between the Geoids of China Mainland and China Sea, which is from the project of Establishing China New Geoid Model, is mainly discussed. It is also simply analyzed that the merged difference of the two kinds geoid is mostly caused by systematic errors, and some principles which the merge of two geoids should stand to are concluded. Finally, both the so-called fitted merge technique and analysis of this technique's feasibility are suggested.
