  • Method Details

    • buildGrid

      protected void buildGrid(int numX, int numY, int power)
      Deprecated.
      Builds a regular grid. Maps the non-grid data into the regular grid using an inverse distance between grid and non-grid points. Weighting of distance can be controlled by setting through the power parameter that controls the exponent used on the distance weighting (e.g., distance^power).
      Parameters:
      numX - number grid points in along the x-axis
      numY - number grid points in along the y-axis
      power - exponent for inverse distance weighting

    • distance

      protected double distance(double xDataPt, double yDataPt, double xGrdPt, double yGrdPt)
      Deprecated.
      Calculates the distance between two points.
      Parameters:
      xDataPt - the x coordinate.
      yDataPt - the y coordinate.
      xGrdPt - the x grid coordinate.
      yGrdPt - the y grid coordinate.
      Returns:
      The distance between two points.
