montaj MAGMAP Filtering

The montaj™ MAGMAP Filtering extension provides a 2D-FFT filter library to allow the application of common Fourier domain filters to gridded data in Oasis montaj.

MAGMAP rapidly processes and enhances gridded datasets by applying a wide range of robust geophysical and mathematical filters. The extension lets you define your own filters, modify the filter specific parameters and apply any number of filters together in a single operation.

An Interactive Spectral filter builder provides an interactive method to modify the filter parameters and to instantly see the effect of the filter on the radially averaged power spectrum.

Use montaj MAGMAP to:

• Apply two dimensional Fast Fourier Domain filters (FFT Filters) to gridded data

• Potential Field Filters

• Reduction of magnetic data to the magnetic pole or equator

• First/second/nth vertical derivatives, including fractional derivatives

• Upward/downward continuations to any horizontal surface

• Apparent magnetic susceptibility maps from magnetic field

• Apparent density maps from residual gravity field

• Optimum Weiner depth filter

• Conversion between different directional components of the field

• Apply General Purpose Filters

• Six different regional/residual separation filters

• De-corrugation and directional filters

• First/second/nth horizontal derivatives
