Zusammenfassung:	An imaging system (10) comprises an imaging data-collection station (11) having a camera (15) with a field of view (16) mounted on platform (13) rotatable about azimuthal axis (14). Collected image data is delivered on line (20) to a monitoring station (12) together with data on line (19) representative of the angular position of platform (13) which is sensed by sensor (18). The monitoring station (12) incorporates at least one channel each channel having a display device (25) having a known display field (30, alpha 1), an operator-actuable sensor (26) which selects a particular angular position ( theta 1), within the wide angle field (17) traversed by fixed field of view (16), a gate device (28) for capturing the pertaining image data from line (20) and a store (29) for storing captured data.
