Translation from PtNorms to Regular
DDS
Grid
PtNorms2dds
Transforms PtNorms data into
a regular, rectangular surface according
to criteria set by the field= argument.
Any
dds supported format
can be used for
the output.
(i.e. usp, fcube, segy, disco, ...)
Syntax Summary
-
PtNorms2dds fn_norms=Input_PtNorms_file
-
out=outfile

axis= x y z
-
delta.x=10
-
delta.y=20
-
size.x=100
-
size.y=200
-
nx=100
-
ny=200
-
format= usp
dx=10
-
dy=20
-
field= X | Y | Z | Tx | Ty | Tz | Time|
EL| AZ| Fold
Field Selection
The field= argument can be used to select any
of the columns from the PtNorms file as the values sent to the
output gridded surface. That is you may elect to create a
time surface, depth surface, direction surface, fold surface,
and even an "x" surface.
-
field= Fold (or F or f ) causes the
output file to contain a count of the
number of rays that hit each bin.
-
field= EL | ELevation | elevation causes
the output dds file to contain the
degrees from vertical of the ray
direction.
(assuming that tx**2+ty**2+tz**2=1. )
-
field= AZ | AZimuth causes the output
file to contain the degrees E of north
(assuming that the 1 axis points north).
-
field= Tx | Ty | Tz causes the output file
to contain the corresponding direction
cosine of the ray propagation direction.
-
field=X | Y | Z causes the output surface
to contain the X, Y, or Z location of
of the ray.
That is, field= Z will cause the output file to contain
a depth surface.
-
field= Time | t | T causes the output file
to contain the travel time.
