Most mapping systems have many parameter switches to adjust surface modeling algorithms. Only a few are frequently used to improve the model, but the ones used often make drastic improvements. Parameters found to be useful affect items such as amount of smoothing, number of data points required, number of sectors (compass directions from which data are used) that must have data, distance to look for data, type of algorithm used, type of filter used, size of grid increment, and whether a coarse regional model is built and refined to the desired detail. | Most mapping systems have many parameter switches to adjust surface modeling algorithms.
