| Zusammenfassung |
| We tested a high-quality laser rangefinder binocular coupled with a GPS
receiver connected to a Tablet PC running dedicated software to help
recognize and map in the field recent rainfall-induced landslides. The system
was tested in the period between March and April 2010, in the Monte Castello
di Vibio area, Umbria, Central Italy. To test the equipment, we measured
thirteen slope failures that were mapped previously during a visual
reconnaissance field campaign conducted in February and March 2010. For
reference, four slope failures were also mapped by walking the GPS receiver
along the landslide perimeter. Comparison of the different mappings revealed
that the geographical information obtained remotely for each landslide by the
rangefinder binocular and GPS was comparable to the information obtained by
walking the GPS around the landslide perimeter, and was superior to the
information obtained through the visual reconnaissance mapping. Although our
tests were not exhaustive, we maintain that the system is effective to map
recent rainfall induced landslides in the field, and we foresee the
possibility of using the same (or similar) system to map landslides, and
other geomorphological features, in other areas. |
