The availability of sufficient high quality information on the minefield scenery is an important prerequisite for the safety and the efficiency of all demining actions. Within the EU project ARC Airborne Minefield Area Reduction a system has been developed for airborne minefield survey for use in General Mine Action Assessment, Technical Survey area reduction and as far a possible mine field delineation, and Post Clearance Quality Control. An important methodological aspect of the selected approach is the pyramidal information structure, which is reflected in the use of satellite data, a helicopter UAV CamcopterTM and in the developed GIS data base structure, allowing for a hierarchical approach to the information starting from an overview of the situation down to the level of detail required for field work. The full AGM Automated Geo-reference Mosaic makes use of the pyramidal flight pattern. Image correlation techniques are used to geo-reference lower altitude imagery towards higher altitude images. Only the single image on top of the pyramidal flight requires manual geo-rectification. The top image contains sufficient contextual information for the image interpreter to manually assign ground control points. After AGM processing for each individual image the results are stored in GEOTIFF file format, thus preserving the original pixel values and full position accuracy through geo-transformation matrix information. The ARC Minefield Test trials have been conducted in Croatia during the period of May 12th 2003 till May 23rd 2003.
