Contact Extension Creates an output vector segment. The vector
egment consists of line segments which trace the intersection of a
plane with the surface of a digital elevation model (DEM). The plane
is defined from the dip and strike angles of the input shape, which
are set by the DIP program. Alternatively, they may be set as
parameters in this program.
Estimation Procedure for Spatial Data Integration Combines multiple
layers of spatial data to derive a favourability model for predicting a
geological event (mineral potential, landslide, etc.). Available
algorithms include probability estimation, certainty factor
estimation, and fuzzy membership estimation. DIGRP must be run
before DIEST
Dip and Strike Calculation Calculates angles of dip and strike for a
set of 3 or more points.
Upward/Downward Continuation Filter Compute upward/downward
continuation of a potential field. The filter is applied in frequency
domain. 2D Fourier transform is first applied to the image. After
filtering, the image is transformed back to the spatial domain.
Vertical Differentiation Filter Compute the Nth order vertical
differentiation of a potential field. The filter is applied in frequency
domain after transforming the image using 2D FFT.
Inverse Distance Interpolation Generates a raster image by
interpolating image values between specified pixel locations using
the Simple Inverse Distance or Weighted Inverse Distance
algorithm.
Natural Neighbour Interpolation Generates a raster image by
interpolating image values between specified pixel locations using
natural neighbour interpolation. This program uses the NNGRIDR
code developed by Dr. D.F. Watson at the University of Western
Australia.
Radial Basis Function Interpolation Generates a raster image by
interpolating image values between specified pixel locations using a
Radial Basis Interpolation Algorithm. This program implements the
Multi-Quadric and the Thin Plate Spline schemes.
Texture Analysis Calculates a set of texture measures for all pixels
in an input image. The measurements are based on second-order
statistics computed from the grey level co-occurrence matrices.
Either texture measures for a specific direction or directional
invariant measures can be computed. The texture measures may be
used as input features to classification algorithms.

Image Grey Level Scaling and Quantization, perrforms a linear or
nonlinear mapping of image grey levels to a desired output range.
This program is typically used to scale data from "high" resolution
(32 and 16-bit) channels to "low" resolution (16 and 8-bit)
channels.
Image Contrast Stretch, Generates a lookup table segment to
perform contrast stretching of image data on database files.
Image Enhancement via Lookup Table, Enhances imagery on disk
by passing it through an 8-bit Lookup Table segment (LUT type
