In the paper we will present the adjustments we implemented on the map
ping procedure. We consider them as important improvements to make the
maps more user-friendly. The improvements concern the implementation
of graphical user interfaces, and the addition of 'map-external' infor
mation. This interface enables the users of the maps to focus onto the
ir specific areas of interest and to determine the position of actors
in the field. In addition the 'map-external' information contributes t
o an objective validation of the maps. The presentation will include a
demonstration of the electronic maps and added tools.
