Used to limit the number of sample data points used for estimating intermediate spatial values. The search neighborhood is divided into eight equal-angle sectors. Constraints on selection of data values to include in the estimation include: minimum and maximum of samples or the number of consecutive empty sectors. If either criteria is below minimum, an interpolated value is not calculated. Applies to any interpolation method where a limited number of sample data points are used to estimate intermediate values.
