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. Reformating of the main computer harddrive will result in change of the machine ID number and will require new licence.
Currently I can accept payments through PayPal system , credit card payment and conventional methods like cheque, money order or bank transfer. International bank transfer will incur 20 AUD (Australian dollars) transfer fee. Credit card payment uses secure Paypal website. Invoices can be sent if required.
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.

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 and Recalculate.This module is for changing format or byte location of existing headers or to recalculate header values using mathematical expression. Two input trace headers can be used in the expression together with all major operations such as: +, -, *, /, (), exp, ln, sqr, sqrt, ^, and more.
- 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.
- Filter - this is band pass filter together with detailed power spectrum analysis. Multiple files can be filtered with single operation. This can greatly improve quality of the segy data.
- Scale and clip - this enables clipping unusually high amplitudes, which can cause serious problems in data loading. Moreover this module provides functionality for scaling samples in order to achieve normalized amplitude range for the entire segy dataset
- Interpolate duplicate or zero trace headers - this modules is useful in situations when some trace headers contain duplicate values or values are not recorded and contain zeros. Duplicate values are often encountered in case of shotpoints recorded as integer numbers. This module will enable conversion of integer shotpoints to floating point numbers with fractional parts and prepares them for use with Segy coordinate writer.
- Segy to jpeg converter - this will enable creation of jpeg images from segy files. Multiple segy files can be selected and converted to jpeg images in single operation. Hundreds of images can be created within minutes.
- Cut multiple segy files. Content of cut files is specified by trace numbers or by XY polygon. All traces with XY coordinates inside specified polygon are copied to output file.
