The paper assesses the potential of lidar to enhance existing records of historic environment, using a case study from a river valley in the agricultural midlands of England. Lidar elevation data at a spatial resolution of 2 m was collected over the valley of the River Dove on the Derbyshire/Staffordshire border. These data were compared with the existing inventory of sites for the study area and with a selected sample of vertical aerial photography. While this assessment is based on a British example, we feel that the results have implications for cultural resource management internationally.

In the paper laser scanning technology as one of the most accurate three-dimensional spatial data acquisition methods that is gaining in popularity in the studies of past landscapes is described. Digital elevation model, produced with REIN for the area around Kobarid, uncovered a unseen view of remains of past human activities and natural processes in the area, from the earliest hill forts, and First World War structures to the recent modifications of the landscape. Advanced visualization techniques have revealed details of known archaeological sites and indicated locations of unknown ones.

The redistribution of forest vegetation types in Slovenia, driven by the expected climate change, has been simulated. The potential spatial changes of forest vegetation have been analyzed using empirical GIS model forecasting the spatial distribution of forest vegetation in relation to climate and other ecological parameters. Based on the three different climate scenarios, the simulations showed that the spatial pattern of forest vegetation will be altered under the impacts of climate change. The results are also relevant for historical landscape management.

The paper gives a comparison of analytical hill-shading and sky-view factor. Analytical hill-shading is the most frequently used relief visualization technique, but it has several drawbacks, the most critical being its inability to represent linear objects that lie parallel to the direction of the light source, and saturation of shadow areas. The article presents a method to calculate sky-view factor that overcomes these problems. It is based on diffuse illumination and can effectively visualize the relief.

This paper proves that effective interpretation of lidar elevation models requires appropriate data visualization. The new method which is based on diffuse illumination enabled mapping of previously unknown archaeological sites and improve existing maps. In addition to the studies of the past cultural and natural landscapes it can be effectively used in other scientific fields in which digital elevation model visualizations and automatic feature extraction techniques are indispensable, e.g. geography, geomorphology, cartography, hydrology, glaciology, forestry and disaster management.
