Seismic Toolkit
Seismic Toolkit (STK) is a tool for seismic
signal processing in a graphical interface. It reads seismic signals
in SAC format, and provides a variety of signal processing, such as
filtering, spectral analysis, polarisation analysis, time-frequency
representation, Hilbert transform, and singular value
decomposition.
Some utilities are included for useful seismological
applications, such as
computation of Seismic Moment Mo, Mantle magnitude Mm and Moment
magnitude Mw, MTPA spectral analysis, plotting focal mechanisms,
computation (and plotting) of instrumental response from poles and
zeros, and some usefull GMT (Generic Mapping Tool) scripts for plotting
signals, responses, and time-frequency in Postscript files for high
quality prints.
Features include:
- Powerful Data Handling – The Seismic Toolkit
accesses its data through a published data interface
- Trace display type – INT new fast
rasterizer engine supports the following display types: wiggle,
variable area, variable density, interpolated density, color filled
modes, or combinations
- Built-in Processing Functions supporting a flexible trace
processing pipeline to handle
processes such as trace scaling, interpolation, filtering or Automatic
Gain Control. Each process module is an object that can be individually
controlled. Applications can replace any default module with their own
- Conversion of segy
file trace header coordinates from one datum to another datum and/or
from one UTM zone to another onespan>
- Segy header viewer and editor
- Over 200 datums and seven different projections supported
- Graphic Overlays – overlay any number of
seismic datasets, display interpretation or annotation data, and
overlay logs or contours using the WellLog or the Contour toolkits
- Local Trace Manipulation – Each trace can be
positioned independently. User has control of trace highlight,
polarity, visibility, color on a trace-by-trace basis. Fast local trace
update
- Virtual Scrolling –
offers fast display of large sections with unlimited zooming in on a
dataset. An image mode pre-rasterizes the data into an image buffer for
faster scrolling or for using into movie loops
- Orientation - support for
drawing seismic traces from left to right, right to left, bottom to top
or top to bottom
- Editing – Editor panels are provided to edit
the attributes of a section, including setting the display type,
controlling the scaling of the data, setting the range of the data, or
setting the interpolation mode. A color editor is available to
dynamically update the colormap
- Hardcopy Output – EPS is standard and CGM+
is a fully supported option
- Qt Integration
