| Zusammenfassung |
| Herein, an aerial LiDAR topographic dataset is analysed and interpolated by
means of geostatistical techniques in order to examine the morphology of a
scree slope area in the Eastern Italian Alps. The LiDAR-derived digital
terrain model (DTM) is analysed using variogram maps as spatial continuity
indexes. This allowed for evaluation of the reproduction of spatial
variability of topography and for the characterization and comparison of
different morphological features occurring in the study site. The results
indicate that variogram maps efficiently synthesise the spatial variability
of topography in a local search window, representing suitable
"fingerprints" of surface morphology. |
