DISCOVERING TERRACED AREAS IN SLOVENIA: RELIABLE DETECTION WITH LIDAR
Location: Ljubljana, Slovenia
LIDAR data offer an unprecedented accurate new interpretation tool for detecting terraced landscapes. The
boundaries of terraced areas in Slovenia cannot be clearly defined without the help of a field survey even when
the configuration of the terrain makes surveys difficult. The segmentation of point cloud data into various classes of
foliage, ground, buildings, and so on makes previously hidden earthwork structures (including abandoned terraces)
instantly recognizable. The conceptual shift is that the LIDAR slope analysis layer is more revealing and instructive for
discovering terraces areas than orthophoto images ever were. Although LIDAR data are a new tool in the search for
terraced areas, orthophotos remain important but are nevertheless only a contextual aid. A quantitative comparison
between the old and new methods shows no difference in three pilot areas, shows only a minor difference in two
cases, and reveals major differences in three pilot areas. The quantitative differences in some of the pilot areas are
compelling. However, the most significant feature of the new method is its reliability for detecting the exact boundaries
of terraced areas.
