| Summary: | In Flanders (Belgium) a large amount of remote-sensing data has been acquired and processed over the past few years, including high-resolution lidar and multi/hyperspectral aerial photography. These new data are contributing to the detection of archaeological sites and the characterisation of the cultural/historical landscape. Of particular use in historically stable areas under forest and pasture, lidar demonstrates the presence of a large number of previously unknown features and sites.
The analysis and modelling of these data, combined with other landscape data such as soil maps, augering data, geological and historical maps, and aerial photographs, also provide possible new instruments for the characterisation and evaluation of prehistoric and historic landscapes.
This vast amount of new remote-sensing data, plus the information it delivers, however, presents not only obvious opportunities but also a number of challenges. A centralised online system was developed by the 'GIS-Flanders agency', storing both processed and raw data from multispectral recordings, airborne lidar, mobile mapping images etc., and presenting several download and visualisation possibilities and tools. A new system has also been set up to handle specific archaeological and cultural historical data (historical images and aerial photographs, archaeological field data). Dialogue is needed so that the preservation and management needs of the archaeological heritage are also included.
