Hi Abhash- That is a good question. However, grdgradient with -D and -S can also return the direction of the gradient or the strike (-Dn), as well as the absolute value of the gradient. If your units are correct (all meters or geographic with -fg (or -M in GMT4)) then take atan of the gradient and that should give you dip, no? -p On Feb 12, 2014, at 3:37 PM, Mr Abhash Kumar <[email protected]> wrote: > Hi, > I have a 2-D grid file for the subducting slab surface. I need to find dip of the slab at a particular latitude and longitude. I looked at the man page of grdgradient and it can only calculate the gradient along a particular azimuth. I would be extremely grateful for any suggestions in this regards. > > Thanks > Abhash kumar > PHD candidate > University of North Carolina at Chapel Hill > To unsubscribe, send the message "signoff gmt-help" to [email protected] To unsubscribe, send the message "signoff gmt-help" to [email protected]
