montaj Geophysics software extension provides a range of filters and
statistical tools for working with large-volume geophysical data.
1D Filters enable field geophysicists to process data by applying a
variety of space domain filters (linear and non-linear).
1D FFT Filter enables you to apply a variety of Fourier domain filters
to one-dimensional (line) potential field and other data.
variety of geostatistical tools provide the ability for summary and
advanced statistics, including histogram, scatter and triplot analysis,
and the ability to subset data based on code or map group
Use montaj Geophysics to:
- Smooth data, with or without non-linear filtering, using
spatial one dimensional filters
- Apply convolution filters, including Difference, Fraser,
Laplace, Low-pass, Band-pass, High-pass, and User-Defined
the shorter wavelength features in the data using one-dimensional Fast
Fourier Filters (FFT). These include regional filters, upward/downward
continuations and vertical and horizontal derivatives
- Apply Lag Correction to a channel of data by shifting the
start fiducial by a specified lag amount
Heading Correction to data for a systematic shift (in the data) that is
a function of the direction of travel for a survey line
- Apply Magnetic base station correction to a magnetic channel
- Perform profile-based processing for interpretation and
multivariate analysis using histogram, scatter and triplot statistical
analysis tools Select and subset data interactively from maps based on
text codes, regions or map groups
