From the above list, selecting the correct gridding algorithm is most notable for Surfer users. Beex uses Surfer to grid and create 3D surface maps from LiDAR data, and he outlines how using different gridding algorithms will result in very different surfaces.
His recommendation for the most accurate surface? Utilize the Kriging method and elongate the search neighborhood.
By stretching the search neighborhood and testing its affect on your dataset you can generate a model that is more representative of the Earth’s surface than utilizing the default search parameters with Kriging. The images to the right are taken from Beex’s article and demonstrate the differences.
