Method for enhancing depth and spatial resolution of one and two dimensional residual surfaces derived from scalar potential data

摘要

An improved method is disclosed for collecting or assembling scalar potential data measurements that are to be subsequently prepared as a surface representation for analysis via frequency domain transform filters. Measurements are made over a geographic reference region which extends in all cardinal directions from the center of some previously determined primary region. The reference dimensions must contain the primary region and must be plural multiples of the greatest depth to be considered in analyzing the contributions to the measurements. A combined or separate improved method for delineating or defining geospatial information contributing to a scalar potential surface is disclosed. This method is implemented using traditional statistical techniques to construct an histogram from the set of values comprising a surface representation. This histogram constitutes a Spatially Correlated Potential Spectrum for the surface. These combined and separate methods improve resolution of geological structures over depths and spatial extents under consideration.
