EMIGMA Premium Series

EMIGMA for Gravity

EMIGMA for Gravity is designed for geophysical data that have already been corrected for the Bouguer anomaly and terrain distortion. (Note: All basic gravity corrections can be done with the auxiliary software QCTool. All EMIGMA gravity licenses are accompanied with a QCTool software license.) The user may do a series of FFT processing procedures including derivative calculation, upward/downward continuation and wavelength filtering. EMIGMA's gridding tools are particularly useful for gravity as they allow for very irregular survey points and rectangular grid cells. Data maps of the original as well as the processed data may be made, printed and exported as GeoTIFFs.

EMIGMA offers standard 3D modeling capabilities, added to which is a new, very accurate technique developed specifically for long strike bodies. Note that EMIGMA's modeling algorithms calculate up to the 2nd order derivatives of the gravitational acceleration vector.

EMIGMA also offers several types of 3D Gravity Inversion.

EMIGMA Gravity is available as part of EMIGMA Premium Complete, as a standalone product or an add-on to other EMIGMA Premium packages.
