A method for sharing visual situational information of objects among a number of command and control units. The method includes the steps of providing to each command and control unit a mechanism for storing a digital reference map of a geographical area, receiving by one or more command and control unit an image of a scene which includes one or more object within the geographical area, registration of the received image of the scene to the digital reference map, updating a situational information of the object in the reference map, and transferring the updating of the situational information to one or more other command and control unit.

What is claimed is: 1. A method for sharing visual situational information of objects among a plurality of command and control units comprising the steps of: (a) providing to each command and control unit a mechanism for storing a digital reference map of a geographical area; (b) receiving by at least one command and control unit an image of a scene which includes at least one object within said geographical area; (c) registration of said received image of said scene to said digital reference map of said at least one command and control unit; (d) updating a situational information of said at least one object in said digital reference map of said at least one command control unit according to said received image of said scene and, (e) transferring said updating of said situational information of said at least one object to at least one other command and control unit among said plurality of command and control units. 2. The method as in claim 1 wherein said digital reference map includes a digitized orthogonal photograph of said geographical area. 3. The method as in claim 1 wherein said image of said scene includes a perspective view of said at least one object. 4. The method as in claim 1 wherein said situational information of said at least one object includes information in regard to a damage inflicted to said at least one object. 5. The method as in claim 3 further comprising the steps of: (f) acquiring of said image of said scene. 6. The method as in claim 5 wherein said acquiring is effected using an imaging device whose location is selected from the group consisting of onboard of an airborne vehicle, on a topographically elevated surveillance point and upon a top of a mast. 7. The method as in claim 1 wherein said image is selected from the group consisting of optical images in the visible, infrared images, thermal images, laser radar images, radar images, images of an output of a chemical sensor and images of an output of a biological sensor. 8. The method as in claim 1 wherein said registering is effected using at least one technique selected from the group consisting of a polynomial transform method, a sensor model transform method and a features matching transformation method. 9. The method as in claim 1 further comprising the step of: (f) displaying visually said digital reference map. 10. The method as in claim 3 further comprising the step of: (f) displaying visually said perspective view of said at least one object. 11. The method as in claim 9 wherein said updating of said situational information of said at least one object in said visually displayed digital reference map includes electronically marking of a registered image of said at least one object in said visually displayed digital reference map. 12. The method as in claim 1 wherein said transferring includes transferring over a digital data link. 13. The method as in claim 12 further including the steps of: (f) incorporating said data-link transferred situational information of said at least one object in said digital reference map of said at least one other command and control unit, and (g) visually rendering by said at least one other command and control unit of said data-link transferred situational information of said at least one object. 14. A system for improving the situational awareness of a plurality of command and control units, the system comprising: (a) a plurality of command and control units; in each command and control unit a database located in an addressable memory of said each of command and control units, each said database storing a digital reference map of a geographical area which includes a location of at least one object under a surveillance of at least one command and control unit; (b) a mechanism for image registration of a scene in said digital reference map in accordance to a received image of said scene which includes said at least one object, and (c) a communication mechanism between said at least one command and control unit and at least one other command and control unit. 15. The system as in claim 14 wherein a command and control unit among said plurality of command and control units is a ground station. 16. The system as in claim 14 wherein a command and control unit among said plurality of command and control units is on board of an aircraft. 17. The system as in claim 14 wherein a command and control unit among said plurality of command and control units is on board a ship. 18. The system as in claim 14 wherein said digital reference map includes a digitized orthogonal photograph of said geographical area. 19. The system as in claim 14 wherein said situational information of said at least one object includes information in regard to a damage inflicted to said at least one object. 20. The system as in claim 14 wherein said communication mechanism includes a digital data link among said command and control units. 21. The system as in claim 14 further comprising: (d) an imaging device to form an image of a perspective view of a scene which includes said at least one object; (e) an image transmission device communicatively coupled to said imaging device, and (f) an image receiving device in said at least one command and control unit communicatively connected to said image transmission device. 22. The method as in claim 21 wherein a location of said imaging device is selected from the group consisting of onboard of an airborne vehicle, on a topographically elevated surveillance point and upon a top of a mast. 23. The system as in claim 21 wherein said imaging device is remotely controlled by said at least one command and control unit. 24. The system as in claim 21 wherein said imaging device is selected from the group consisting of optical imagers in the visible, infrared imagers, thermal imagers, laser radar imagers radar imagers, chemical imagers and biological imagers. 25. The system as in claim 21 further comprising: in said at least one command and control unit; (i) a display for displaying visually said digital reference map stored in said at least one command and control unit; (ii) a display for displaying visually said image of said scene and, (iii) a mechanism for marking of a selected object among said at least one object in said digital reference map stored in at least one command and control unit in accordance to said situational information of said selected object. 26. The system as in claim 20 wherein said at least one other command and control unit includes a mechanism for visually rendering of data received via said digital data-link. 27. The system as in claim 26 wherein said at least one other command and control unit includes a mechanism for incorporating said visual rendering in said digital reference map stored in at least one other command and control unit.
