Methods include inverse distance, moving weighted least squares and polynomial fitting. The user has full control over grid dimensions, densities and weighting factors. Unlimited points and grid sizes. Contouring Contour maps can be created at any interval and be smoothed and labeled according to their value. Colors and line thicknesses can be assigned to labeled and unlabeled contour lines and contour labels.
Automatic annotation includes titles, x,y axes with tick marks and borders.
A Delaunay triangulation routine is also available for creating contour maps directly from x,y,z data. Point Maps Control point maps using any of 20 different symbols can be automatically created from the initial data set. Label size, color and offsets are user-defined. The GridMath program allows you to mathematically manipulate grid models. The Trend Surface module creates 1st through 6th order polynomial trend surface grids and extracts residuals.
