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.
