- Abstract
- The utilisation of airborne laser scanning (Light Detection And Ranging, LiDAR) technology in archaeological research has developed signifcantly in recent years. The application of specifc algorithms to appropriate software can provide an accurate digital model of the Earth’s surface from LiDAR datasets, which helps to identify archaeological objects by the use and comparison of different visualisation techniques of the digital terrain model (DTM). Besides using LiDAR data, the application of various methods (e.g. documentation by terrestrial laser scanner and Total Station, aerial photographs, modern and historical maps, archaeological information, historical documents, on-site examination of earthwork features) helps to assure a more precise identifcation and interpretation process of the archaeological features. In addition, the Geographical Information System (GIS) offers a good solution for managing together all these various types of information in the same coordinate system. In this paper, the application of LiDAR analysis in GIS environment will be discussed and compared in two different research programmes. The HiMAT programme (History of Mining Activities in the Tyrol and adjacent areas) investigates the history of mining in the Eastern Alps and the APSAT project (Environment and Landscapes of Upland Sites of Trentino) focuses on the study of the upland anthropic system in Trentino area. In both research projects, LiDAR surveys were applied to investigate the archaeological areas such as mining regions and hilltop sites of upland areas. Some of the results from the sites surveyed by LiDAR and additional methods are presented in this paper including the discovery of new sites and the detection of new structures at known sites as well as the mapping of archaeological settings.
