Zusammenfassung |
Within the framework of FP7, an EU-funded SafeLand project, a questionnaire was
prepared to collect information about the use of remote sensing for
landslide study and to evaluate its actual application in landslide
detection, mapping and monitoring. The questionnaire was designed using a
Google form and was disseminated among end-users and researchers involved in
landslide studies in Europe. In total, 49 answers from 17 different European
countries were collected. The outcomes showed that landslide detection and
mapping is mainly performed with aerial photos, often associated with
optical and radar imagery. Concerning landslide monitoring, satellite radars
prevail over the other types of data. Remote sensing is mainly used for
detection/mapping and monitoring of slides, flows and lateral spreads with a
preferably large scale of analysis (1:5000–1:25 000). All the compilers
integrate remote sensing data with other thematic data, mainly geological
maps, landslide inventory maps and DTMs and derived maps. According to the
research and working experience of the compilers, remote sensing is
generally considered to have a medium effectiveness/reliability for
landslide studies.
The results of the questionnaire can contribute to an overall sketch of the use
of remote sensing in current landslide studies and show that remote sensing
can be considered a powerful and well-established instrument for landslide
mapping, monitoring and hazard analysis. |
