1. Providing mapping rectification of earth''s surface radiation scanned by an artificial satellite along scan lines which are substantially perpendicular to the satellite orbital plane, said satellite transmitting radiation scan signals varying as a function of a radiation parameter along each scan line, comprising the steps of: applying the radiation scan signals transmitted by the satellite to a cathode ray tube having a concave screen congruent with a spherical surface to generate on the screen a succession of images, each image corresponding to a scan line and having a visible parameter which varies as the radiation parameter of the scan line to which it corresponds; placing the front nodal point of a photographic camera at a point on said spherical surface which corresponds to one of the North and South poles of the earth and which is at the same relationship with the image on the cathode ray tube screen with respect to the spherical surface as the relationship between the scan line and the earth pole corresponding to the pole at which the camera lens front nodal point is placed; photographing the image on a photosensitive surface contained by the camera, said photosensitive surface placed perpendicularly to a line connecting the camera lens front nodal point and the center of said spherical surface.
2. Providing mapping rectification as in claim 1 including providing a compensation for the earth''s rotation with respect to the satellite orbital plane by means of rotating the photosensitive surface inside the camera around an axis connecting the front nodal point of the camera lens and the center of the spherical surface at a velocity corresponding to the earth''s rotation with respect to the satellite orbital plane.
3. Providing mapping rectification as in claim 1 including providing compensation for the satellite orbital motion by establishing and maintaining relative motion between the cathode ray tube and the camera, with the front nodal poiNt of the camera remaining on the spherical surface and the cathode ray tube screen remaining congruent with the spherical surface, said relative motion corresponding to the relative displacement of satellite scan lines with respect to the earth poles.
4. Providing mapping rectification as in claim 3 including providing compensation for the earth''s rotation with respect to the satellite orbital plane by means of rotating the photosensitive surface in the camera around an axis connecting the front nodal point of the camera lens and the center of the spherical surface at a constant velocity corresponding to the rotation of the earth with respect to the satellite orbital plane.
5. Providing mapping rectification of earth''s surface radiation scanned by artificial satellite along scanning lines comprising the steps of receiving from an artificial satellite radiation scanning signals of the earth''s surface, applying said signals to a cathode-ray tube having a spherically concave screen surface to generate an image on said concave screen surface, the attitude and shape of said image being made proportional in attitude and shape to the actual attitude and shape of the radiation scanning lines on the earth''s surface by appropriately deflecting the electron beam of said cathode-ray tube.
6. Providing mapping rectification of earth''s surface radiation scanned by artificial satellite according to claim 5 including placing the front nodal point of a camera lens at a point corresponding to one of the South and North Poles of the earth on a spherical surface which coincides with the screen surface of the above-mentioned cathode-ray tube, and causing an image produced on said cathode-ray tube screen to coincide with a polarstereographic map by projecting said image on a photosensitive plane that is placed perpendicularly to a straight line connecting the center of said spherical surface and the front nodal point of said lens.
7. Providing mapping rectification of earth''s surface radiation scanned by artificial satellite according to claim 6, wherein an accurate radiation image of the earth''s surface is obtained as polarstereographically mapped by compensating for the effect of the earth rotation by means of photographing the image shown on the cathode-ray tube screen while rotating the camera, with the front nodal point of the camera lens being placed at a point corresponding to one of the South and North Poles of the earth on the spherical surface that coincides with the screen surface of said cathode-ray tube around an axis passing through said one of the South and North poles and through the center of said spherical surface.
