摘要

摘要: 以南通幅海洋重力编图为例,论述了如何应用海洋重力与陆地重力以及卫星重力数据等不同来源的重力数据进行海洋重力编图。讨论了编图中关键问题,如各种数据的统一改算问题,包括统一的重力基准网、统一的正常重力公式、统一的投影方式;不同来源数据间的拼接调平问题;卫星重力数据使用范围问题等,并对最新的南通幅编图结果与以往相同范围内的编图进行了比较。

Abstract: Taking gravity mapping of Nantong sheet as an example, this paper introduces how to use different kinds of gravity data for marine gravity mapping. In this case, marine gravity data, continental gravity data and satellite-derived gravity data are used. Data correction with the same standard including the same gravity base net, the same gravity normal formula and the same projection method, merging data of different sources into one integrated data set and the problem of using satellite derived gravity data are discussed. A comparison is made between this new gravity map of Nantong sheet and the former maps.
