Confronto sperimentale tra superfici a ceduo tagliate a raso osservate mediante immagini satellitari ad alta risoluzione e tagliate riscontrate amministrativamente

摘要: Abstract: The aim of this work is to test the potential SPOT5 satellite images for monitoring coppice clearcuts. clearcuts, delineated by on screen interpretation images, are compared with administrative statistics reported a sample 230 units. Administrative result significantly lower than those an average ratio between clearcut area observed within each unit and corresponding equal 1.45. underestimation data likely due simplified process authorization clearcuts as well eventual lack timeliness and/or loss that sometimes hinder information flow from bodies National Forest Service, in charge feeding official forest statistics. In light experimentation carried out, operational procedure proposed statistical calibration about
