2. Definiation of Photogrammetry 
  
This point refers to question 2. We think that the standardization of the PKL 
of Soil Photointerpreters only can be clearly established after a clear de- 
finition of Photogrammetry, or at least after an unequivocal delimination of 
the real scope of this science. To be more explicit I will take some statements 
made by Gruner (1980) in the Fourth Edition of the Manual of Photogrammetry. 
As he says, in the previous editions of the Manual of Photogrammetry, the de- 
finition of Photogrammetry was given as: "the science of art of obtaining re- 
liable measurements by means of photographs".
