1• Classic methods for point transfer .1 1.1 The most rigorous method for this purpose is to use signalized tie points. However costs for field crews are considerable. 1.2 Another method uses natural points (stones, tufts of grass..) that can easily be identified on the photographs. Some manufacturers offer point transfer devices which permit to engrave a circular mark around around the selected points. 1.3 In Cctse that no natural points can be found, artificial points must be marked by a mechanical device. 1 •k Three-stage-comparator permit point transfer without mechanical dammage of the emulsion. However the price for such an instrument is likely to be higher than for an ordinary stereocomparator. 1,5 In order to avoid the disadvantages of the different point transfer methods, Albertz, Kreiling, Wiesel developed a block adjustment program which is based on parallax measurements in overlapping photographs. Point transfer is no more necessary. 2, Use of an analytical plotting instrument for point transfer 2.1 Principle The conception of an analytical photogrammetrie instrument permits to store coordinates of transfer points in core № mory of the control computer. When in course of strip measurements photo 1 will be replaced by photo 3 , the photo coordinates of tie points in photo 2 are still available. This permits to move the floating mark
