Constructors

Constructor and Description
GriddedLatLonSet(MathType type, float[][] samples, int lengthX, int lengthY) a 2-D set whose topology is a lengthX x lengthY grid, with null errors, CoordinateSystem and Units are defaults from type
GriddedLatLonSet(MathType type, float[][] samples, int lengthX, int lengthY, CoordinateSystem coord_sys, Unit[] units, ErrorEstimate[] errors) a 2-D set whose topology is a lengthX x lengthY grid; samples array is organized float[2][number_of_samples] where lengthX * lengthY = number_of_samples; samples must form a non-degenerate 2-D grid (no bow-tie-shaped grid boxes); the X component increases fastest in the second index of samples; coordinate_system and units must be compatible with defaults for type, or may be null; errors may be null
