Fuzzy multi-temporal land-use analysis and mine clearance application

This paper puts forward a pixel-based and a region-based method for detecting land-use changes using a multi-temporal pair of satellite KVR panchromatic and aerial Daedalus multispectral images. These methods, based on fuzzy logic, provide a confidence level of their post-classification change detection results. They were applied to support an early stage of mine clearance in Croatia, where mines laid during the latest conflict (1991 to 1995) cause disruption in the land-use evolution. They were used for locating the agricultural land that was abandoned during the war and is therefore considered as a mine contamination indicator. The mere location of the abandoned agricultural land is of limited use for supporting mine clearance. On the other hand, the integration of the location and spatial confidence level can help the mine experts in their decision making by evaluating both unlikelihood and likelihood of a plot of land to be abandoned.
