A new explainable DTM generation algorithm with airborne LIDAR data: grounds are smoothly connected eventually. (arXiv:2208.11243v1 [cs.CV])

The digital terrain model (DTM) is fundamental geospatial data for various
studies in urban, environmental, and Earth science. The reliability of the
results obtained from such studies can be considerably affected by the errors
and uncertainties of the underlying DTM. Numerous algorithms have been
developed to mitigate the errors and uncertainties of DTM. However, most
algorithms involve tricky parameter selection and complicated procedures that
make the algorithm's decision rule obscure, so it is often difficult to explain
and predict the …
