Delete Height Points and Height Points Multifile Import
By the command "Delete Height Points" height points can be deleted when the amounts of height points for a digital terrain model is too large and too detailed. After executing the command and entering a height, the height points are deleted which deviate from each other less then the defined height. By this procedure the number of height points will be reduced accordingly and calculation speed will be improved.
Delete height points
Feature "Multifile Import" allows to achieve deleting height points also when importing height point data. Several files of type „ASCIIObject“ can be selected in parallel and therefore even import of very large terrain models can be easily processed.
