This report describes a study performed in the autumn of 2006 within the project "Technical Decision Support" (TEBE). The purpose of the study was to continue studies initiated during 2005 regarding which type of geographical information that is critical for international missions in urban environments. Besides identifying which geographical information that is critical, the study has also addressed issues regarding resolution of map information, how fragmentary geographical data from different sources could be integrated to one dataset for visualisation in 2D and 3D, and which kind of terrain analysis that can be performed on this type of data. The study is based upon, like previous year, earlier work about dynamic decision making, geographical information for tactical command and control, extensive interviews performed with Swedish officers with solid experience from critical situations in international environments. New for this study is the use of theories regarding Planning Under Time pressure, PUT. The study has been performed during a number of workshops, by means of a research platform used to highlight different aspects of the research areas mentioned above. The results are based upon discussions during the workshops and analysis of recordings from the different workshops.
