Given picked stacking velocities, is there an easy way to grid and visualise them?
If I pick every 100th CDP, I would like to see a full velocity model for the line, in either time or depth.
Cheers

Hi unisam and unisam2 can do the job of interpolation. 1) you pick what you can in a file (suximage mpicks=), one file/cdp with the CDP number in its name 2) transform the file in a par file (mkparfile string1= string2=, according to unisam parameters) 3) regularize your pick with unisam in a binary regularly sampled file with the cdp number in its name too 4) make a 2D interpolation of the 1D cdp analyses with unisam2, using the cdp numbers in a binary grid...
easily scriptable, of course
That's it ! At least, it's the way I do :-)
Good luck D.
Sorry, I have no SU installation by me, I can't check the parameters...
