Abstract

Method and applied systems for point determination of material structures from long distances (4,000 û 16,000 meters), with simultaneous digital recording thereof in a geographical information system (GIS), applied by two users, walking or wheeled or by one walking and one wheeled user, by the use of a portable system for detecting material structures from long distances, operating by the exploitation of the magnetic resonance effect, as previously described in the patents GR1005224, GR1004926, and the patent application 20060100352. The method requires two users, the one (65) moving independently from the other (66) and by the use of a portable magnetic resonator (1) they locate the precise direction of the material structure (44), the position of which is determined as a point from the intersection between the directions ((70), (69)) of the two magnetic resonance devices (1), by the portable computer carried by the users or on a vehicle (10). The position ((66), (67)) and the direction ((70), (69)) of the users is determined by the portable GPS device (57). A mobile-telephony relay system (e.g. a 3G card) (36), relays the signal ((63, 64)) from the one user (66)to the other (67) and to all the computers (35) of this particular aerial network, so that each user knows the position and direction of the other from the relevant points ((9), (43)) on the screens of their computers, and direct themselves. This intersection point between the lines (45) is the exactpoint where the material structure (44) to be investigated is present. The method solves serious problems, such as that of the automatic recording of minefields, ôsuspect areasö, non-recorded minefields, other minefields laid randomly, non-standardized explosive materials, without any plan for laying or removal elements for these. It provides the advantage of the automatic digital recording without entering the minefield, the operation being instead performe mplete safety. Also, it allows the remote digital recording of explosive materials from long distances, the terrorist-owner being unaware of that, resulting to the ôinvisibleö surveillance and recording of the actions of terrorist groups.
