摘要
Abstract
Taking a typical gulf region for example,the paper studies the transfer and unification of land and sea vertical datum according to practical principles and accuracy.This paper combines methods of MSL transfer and GPS height fitting to set up the unified vertical datum in the typical gulf region.It carries out the seamless contiguity of coastal topographic maps and bathymetric charts.The study shows that the algorithm is feasible and the technique route is very correct,and it can meet the demands of mapping in gulf regions.关键词
