Dear GMT community.
I am using GMT for my research a while ago but does not familiar to tackle this problem.
I have a text file that contains 4 columns(long, lat, depth, and values) at regular intervals.
Is it possible to make a 3D grid w.r.t 4 columns and later extract the values and plot at a specific depth?
below images will be an ideal solution but I could not get it with xyz2grid.
Thank you very much
