AbstractMAXIMA is a Geosoft GX implementation of a method of identifying local maxima from gridded data described by Blakely and Simpson (1986). The routine determines local maxima in 1, 2, 3, or 4 directions. The position of the local maximum value is calculated from 9 local grid cells and is an improvement on methods using grid cell centres as the position of the maxima. Local maxima can be discriminated by a user supplied minimum input grid value. The output maxima are written to a Geosoft GDB file.
Summary(Plain Language Summary, not published)
MAXIMA provides a method of identifying local maxima from gridded geophysical data. Input gridded data can be filtered so that a local maximum represents a boundary between sources with different physical properties. The local maxima aid the interpretation of geophysical data by marking the boundaries of geophysical domains. The routine determines local maxima in 1, 2, 3, or 4 directions. The position of the local maximum value is calculated from 9 local grid cells and is an improvement on methods using grid cell centres as the position of the maxima. Local maxima can be discriminated by a user-supplied minimum input grid value.
