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.
