The case-study area of St. Anna mainly functions as a test site for airborne laser scanning. The area of this former friary of the Discalced Carmelites is wooded, mainly with deciduous trees, with a varying degree of vegetation (mixed oak/beech with and without under storey, cleared parts overgrown with bushes, meadows) and archaeology (prehistoric hill-fort, round barrows, a ruined medieval castle, other stone structures (a monastery, remains of a medieval farm, surrounding wall etc.), stone quarries, lime kilns, field boundaries, and hollow-ways.
Before the start of the LBI ArchPro, the area had been scanned in 2006 and 2007 in high resolution and according to archaeological principles as part of the project LiDAR-supported archaeological prospection in forest areas (FWF Austrian Science Fund P 18674-G02). Therefore it is an ideal case-study area to thoroughly test various parameters in airborne laser scanning (see section methods).
Additionally, St. Anna has been also chosen to interpret a detailed mapping of the archaeological structures visible in the DTM for landscape archaeology.
