Airborne laser scanning and Mediterranean environments - Croatian case studies

Abstract

Airborne Laser scanning (ALS, also referred to as airborne LiDAR) is a widely used data acquisition method for topographic modelling. During the last decade, it had a huge impact on the archaeology of forested areas. The advantage of ALS is that the active laser is able to provide information on the topography below the tree canopy, resulting in dense and precise digital terrain models (DTM). Especially full-waveform (FWF) ALS systems show considerable advantages for the generation of DTMs in vegetated areas, as the FWF-parameters might improve classification of ALS data into terrain and off-terrain points, resulting in greater DTM quality and higher potential for the subsequent archaeological interpretation. So far, ALS proved to be extremely successful in central and northern European deciduous forests. It has, however, never been tested in Croatia with dense Mediterranean vegetation, which is a challenge for ALS: the vegetation is considerably low, extremely dense, and contains a considerable amount of evergreen plants. In 2012, a test flight was organised in the area of the Cres / Lošinj archipelago using a current FWF laser scanning system. The results of this data acquisition campain will be presented and discussed within the presentation.
