I have RTP magnetic data and calculated analytic signal (AS) of the data. The program occured AS map and AS.grd files. How can I export the AS.grd file from oasis montaj to surfer or obtain in xyz file format?
First select "Grid and Image" from the toolbar. Then click "utilities", select "copy/convert", ---> select input grid file, ---> output grid file ---> browse, then click save as type, finally you will see surfer V6 or V7 format.
