Block adjustment

As block adjustment or block compensation in the will photogrammetry simultaneous adjustment of numerous aerial photographs indicated.

The method was developed in the 1970s at several technical universities and replaced the previously prevalent method of image models from stereoscopic image pairs (two photograms each ), which were then linked together.

The advantages of the block methods, which have been prevalent since around 1980, are a higher level of accuracy and a lower number of terrestrial control points required ; a certain disadvantage is their significantly higher computational effort.
