Geologically Driven Geophysical Consulting

Custom Software Development

Services we provide

With a history of leading in development of processing algorithms, PGW can quickly assess your requirements and come up with an appropriate software solution that fits your exact requirements.

Some of our GXs are shown on this web site. These executables rapidly process large amounts of data to client-derived using the latest in algorithms and the depth of knowledge available through PGW.

  • Decorrugation and Microlevelling

    The GX's, decorr.gx and miclev.gx, implement PGW's algorithm for microlevelling, which removes any low amplitude component of flightline noise still remaining in airborne survey data after tie line levelling.

  • Compu-drape™ 1D for Profile Data

    The Compu-DrapeTM1D GX performs height continuation on aeromagnetic profile data to transform it from the original magnetic field on an arbitrary observation surface to the magnetic field on a new surface of specified height. Its most useful application is to remove the effects of variation in terrain clearance from line-to-line and/or at traverse-tie line intersections.

  • Compu-drape™ 2D for Grid Data

    The GX, drape2d.gx, drapes potential field data to any reference surface. PGW’s well-proven Compu-Drape technique can be applied to...

  • Total Field Calculated from Horizontal Gradients (GRAD2TMI)

    GRAD2TMI.GX (horizontal gradients to total field) is an Oasis montajTM based GX tool for calculating a total magnetic field grid from two horizontal gradient Hx and Hy grids (Nelson, 1994).

  • Keating Magnetic Correlation Coefficients for Kimberlite Explora

    Keating's method utilizes a simple pattern recognition technique to locate magnetic anomalies that resemble the response of a modelled kimberlite pipe. The magnetic response of a vertically dipping cylinder is computed in grid form. The model parameters that may be adjusted include the depth, radius and length of the cylinder, the local magnetic inclination and declination, and the spatial e...

  • Source Edge Detection (SED)

    SED GX estimates the location of abrupt lateral changes in magnetization or mass density of upper crustal rocks. Its procedure is to identify maxima on a grid of horizontal gradient magnitudes.

  • Source Parameter Imaging™ (SPI)

    SPITM is a quick, easy, and powerful method for calculating the depth of magnetic sources. Its accuracy has been shown to be 20% in tests on real datasets with drill hole control.

  • Continuous Reduction to the Pole (VaryRTP)

    The local inclination and declination of the Earth's magnetic field can vary quite dramatically over large regional surveys. One value of inclination and declination will not satisfy the reduction to the pole operator at all places on the grid.
