GEOCONV (non-standard SU module)
Used to convert stacking velocity functions picked in Geodepth and output in the standard 3D Handvel format into uniformly sampled depth/interval velocity functions (again in standard Geodepth ASCII format) that can then be gridded into a volume.
geoconv < rms_in.ascii nt= dt= nz= dz= > int_out.ascii
Required parameters :
nt= : The number of time samples the input functions are interpolated too prior to conversion to depth.
nz= : The number of output depth samples for the interval velocity functions.
Optional parameters :
dt=50 : sample rate to interpolated the vertical functions too prior to conversion to depth (in ms)
dz=50 : sample rate to output the vertical functions in depth (m).
npairs=50 : maximum number of time picks allowed for any one location.
outform=geodepth (this outputs in Geodepth's ASCII 3D Handvel format). The other option is 'excel' which outputs in a column format
Example :
1. geoconv < geodepth_rms.ascii nt=131 nz=241 > geodepth_int.ascii
This example will interpolate each of the supplied stacking velocity functions to 50ms (to a maximum time of 6500ms) and then convert them to depth/interval velocity functions with a sample rate of 50 m and a maximum depth of 12000m.
2. geoconv < geodepth_rms.ascii nt=131 nz=241 outform=excel > list_int.ascii
As example 1 except that the functions are output as a list suitable to inputting to Excel for plotting.
