Hi Lester, I am pretty sure it can be done with GMT, but some scripting programming could be required. If you want command-line solution to process bulk amount of data it is certainly way to go. The other answer might be off the list, but there is "magpick" program available from http://www.geometrics.com/geometrics-products/geometrics-magnetometers/download-magnetometer-software/ direct download link: ftp://geom.geometrics.com/pub/mag/Software/magpick-latest.exe MagPick can load / save GMT grid NC files. It also has all potential fields transformations implemented, such as reduction to the pole, analytic signal, pseudo gravity etc. There are some limitations however: 1. Grids must be projected (not Lat/Lon grids) 2. There should be no gaps in the grid. This could be circumvented by making transformation and clipping grid after. There is also Linux version with the same functionality, not widely used. Let me know if you are interested in Linux. I hope it helps, Best Regards Mikhail Tchernychev On 2/4/2014 1:21 AM, Lester Anderson wrote: > Hello, > > Is there a way to get the pseudogravity from magnetics using GMT yet? > I have not spotted that option in any of the obvious functions. > > Cheers > > Lester > To unsubscribe, send the message "signoff gmt-help" to > [email protected] PLEASE NOTE: This message, including any attachments, may include privileged, confidential and/or inside information.
