ABSTRACT
Rational planning of cultural landscape is one of the main challenges for the urbanization process within a military landscape of fortified areas. Local authorities governing spatial planning need reliable studies and techniques to evaluate the planned changes in the landscape. The indispensable information might be obtained from GIS and spatial analysis based on integration of different data sources. When dealing with landscape of modern fortification one might rely on Digital Terrain Model (DTM) and Digital Surface Model (DSM), for which one of the best sources is Airborne Laser Scanning (ALS). The paper presents results of experimental studies using an ALS datasets (from a country-wide project) for three different fortification complexes in Poland. The ALS datasets analyses resulted in the detailed and reliable models which can be of use for the evaluation of prospective urban changes. The presented approach takes into account the quality of the ALS dataset in order to provide reliable results of spatial analyses. Subsequently, we generated and integrated ALS derived DTM and DSM with other data sources such as historical plans and CAD designs. Finally, the results from an integrated approach of spatial analyses were visualized.
