Geophysics
Seismic Segy Toolkit
(Seismic
Datum Converter)
Version 3.5 available
now
Windows Vista compatible
This
software was initially developed for conversion of trace header coordinates in
segy files , but it has grown significantly and now offers much more.
Version
3.5 contains new module for padding missing traces in 3D segy files.
Version
3.4 contains new module for writing coordinates to 3D segy file. Coordinates are
calculated from three corner points and written to specified trace headers.
Version
3.4 extends 3D cutter module to allow for blanking of traces inside XY polygon.
Traces from 3D segy file, which lie inside polygon are set to zero, but trace
headers remain unchanged. This may be usefull if part of the 3D data is confidential
and needs to be excluded.
Version 3.4 contains also
many improvements and bug fixes, so it is highly recommended to install this or
later versions of Seismic Toolkit software. Release codes remain unchanged, so
if you have already purchased the licence, you do not have to pay any additional
fee.
Version 3.3 added
new module for converting coordinates (easting and northing) in ascii files. Coordinates
can be converted between different projections and geographical datums. This can
be useful if interpretation files need to be converted to new geographical datum
or different UTM zone.
Version 3.3 added new version
of 3D cutter module. 3D segy files can now be cut using polygon with XY coordinates.
All traces, which are inside polygon can be extracted from input file and saved
to new cut version of the file.
Version 3.2
added support for Windows Vista. Due to restricted access to system directories
there was problem using software under Windows Vista in earlier versions.
Currently
Seismic Toolkit contains following modules:
Seismic
Datum Converter. This module enables conversion of segy files trace header coordinates
between different UTM zones and/or between different geographical datums. Currently
over 200 datums are supported. 7 projections can be used in datum transformation.
Currently supported projections are: UTM, Transverse Mercator, Albers Equal Area
Conic, Lambert Conformal Conic (1 parallel), Lambert Conformal Conic (2 parallels),
Mercator, New Zealand Map Grid (NZMG). Multiple files can be selected.
Segy
Coordinates Writer. This module enables writing of coordinates to segy trace headers.
Coordinates are read from ascii navigation file and written at specified header
location. Software performs necessary interpolation or extrapolation of coordinates.
Multiple files can be selected.
- Segy 3D coordinate
writer. Coordinates are calculated from 3 corner points and written at specified
trace headers.
Trace
Header Viewer and Editor. This module enables
viewing of trace headers in four different formats (ibm float, ieee float, 32
bit integer, 16 bit integer). Headers can be edited and values of headers written
back to segy file in any of these formats. Interpolation of headers is also possible.Values
of the header in any of these formats can also be displayed on graph. Ebcidic
and binary header editors and viewers are also available.
- Reformat,
Add, Multiply.This module is for changing format or byte
location of existing headers and to multiply header by number or to add number
to existing header value
Trace
Header Report. Values of up to four different trace headers can be reported and
saved to text file. User specifies location and formats of reported trace headers.
Multiple files can be selected for reporting.
- Segy
file validator. This module enables validation and editing of some basic header
values, such as: number of samples per trace, sample interval and trace sample
code (format). Multiple files can be selected for validation and files with incorrect
header values are immediately distinguishable. They can be edited and correct
header values recorded back in the segy files.
- Cut
segy file. Module enables creation of new segy file, as a subset of input file.
It also enables extension of traces by adding zero samples to the top or bottom
of traces. Traces with all samples set to zero can also be added to the beginning
or end of segy file.
- Null segy file. Module enables
samples or whole traces in segy file to be set to zero.
- Concatenate
segy files. Module enables concatenation of two (or more) segy files. The result
of this process is a new segy file with traces coming from two input segy files.
- Cut 3D - Module enables creation of subset of
3D segy data file. Selection of data is based on inline and xline ranges, and
on coordinate ranges. Individual inline and xline can be selected and saved as
2D segy data files. Blanking of traces inside XY polygon.
- Pad
3D - Module enables padding missing traces in 3D segy files. Traces can be padded
to rectangular shape or alternatively only missing xlines inside inlines are filled
in. Some seismic software packages have difficulty handling missing traces in
3D segy files and padding them will eliminate the problem.
- Ascii
XY converter - converts XY coordinates in ascii files. Coordinates can be converted
between different projections and geographical datums.
Available
for download is complete version of Seismic Toolkit with all the modules included.
Available
for download is demo version of the software. Most of the features are disabled,
but others are fully functional. Demo version can be used and does not require
release key, but it has limited capability. If you decide to use full version
of the software you will have to provide your machine
ID number (see title bar of registration window) and pay registration fee.
I will send you the release code and you will be able to use full version of the
software. One registration fee covers license for one computer. Any more licenses
will require additional fee. The release code is based on machine ID number and
will not operate on any other computer.
Currently
I can accept payments through PayPal system , credit card payment and conventional
methods like cheque, money order or bank transfer. Credit card payment uses secure
Paypal website.
I have decided to
develop this software myself, because I could not find any product, which provides
these functionalities at reasonable cost. I have been using it extensively here
in Australia, but it can be useful anywhere, where segy files are used. It can
easily be extended to support more datums for datum conversions. Please contact
me, if other datums are required.
If you have any questions or suggestions regarding the software, please contact
me on my email .
