Hi,
Currently, I am using an ASCII grid and I would like to calculate the MBA and RMBA.
Since I am working on the land (continent), it is necessary to use the bathymetry to compute the effect of the water or should I use the topography? According to that what’s the computing methods?

Thanks!!!

please use topography alone. Since your work is restricted to the continent.

Does anybody have an example script for full shipboard gravity to RMBA?
