Description
Create velocity model
This procedure convert grey scale "bmp" image into the velocity depth model.
Inputdata – Grey scale bmp image
Outputdata – Velocity depth gather
Visual – Velocity depth model
Parameters
file name
256 color grey scale bmp image. In order to produce the model from final datum the layer above surface must be filled with blue (RGB: 0:0:255) color
DeltaX
Horizontal size of one pixel of the image
Default: 1
DeltaZ
Vertical size of one pixel of the image
Default: 1
Datum
Provide the datum value.
Default: 1000
Velocity for white color
Velocity that corresponds to the white color of the image
Default: 1600
Velocity for black color
Velocity that corresponds to the black color of the image. The velocities corresponding to the colors differs from white/black will be interpolated
Default: 5000
Blue color velocity
Velocity that corresponds to the blue (RGB 0:0:255) color of the image. This velocity will be used to fill model above the topography level, the topography will be determined as top of the layer below blue. The elevation below the final datum equals to zero will be written in to the output SEG-Y trace header as positive number
Default: 0
Smooth Value(0 - no smoothing)
Smooth of the output velocity model
Default: 10
