Abstract:
The method of transformation of a vectorized situation from remote-sensed data to digital map, using fictive points, by means of rational polynoms of different degrees is reported. Those points are not really existing corresponding points of entities and their images in the picture. Actually they are the intersections of appropriate corresponding lines both on the map and on the picture (photo). These lines have been drawn through the identical edges of contours and also new vectors, formed by fictive points. Those ones were used to calculate transform parameters of rational polynoms. We may take the degrees of polynoms (the numerator and denominator) separately from the first to the third degree. The degree of rational polynoms be applied depends on situation in the map and on the geometry of material in use. If any coefficient in particular polynoms of 1t, 2nd or 3d degree, making near zero contribution, useful to eliminate it. This enlarges degree of freedom in resolution. These parameters are used for transfer entity of actualization direct from picture on the digital map. Method was tested on the special maid application ad models and on real images and maps.
