Monitoring cultural heritage by comparing DEMs derived from historical aerial photographs and airborne laser scanning

摘要: Abstract This paper presents results from a study where identification and documentation of landscape changes using combination historical aerial photographs newer airborne laser scanning (ALS) data were examined. The was based on remotely sensed covering Norwegian protected cultural environment consisting several pebble-stone built grave cairns. Georeferenced digital elevation models (DEMs) generated air the years 1968, 1979 1999. In addition ALS datasets 2008 2010 used in study. Altogether seven difference as result conducting automated change detections between different epochs. this way detailed information about that occurred to individual monuments for almost last 50 years obtained. Further, incidents caused identified interpreted documents archives. Using approach dynamic character studied site proven. demonstrates importance valuable source makes possible retrospective monitoring past scale.
