USE OF THE SPATIAL EFFECT FOR PHOTOGRAMMETRIC DETERMINATION OF THE NEAR-SURFACE MASS-MOVEMENTS AND OTHERS DURING THE GEOLOGICAL RESEARCHES

Summary
The article deals with the spatial effect obtained during the spectroscopic examination of two photograms executed out of one site at an equal spatial orientation of the projection plane (plate), differing, however, on each photogram, by the situation changes of the terrain photographed. Situation changes that cause the change of spatial location of some portions of the terrain photographed are to be seen under the stereoscope as the spatial effect that can be presented quantitatively.
Therefore, if we successively make, after a definite time interval, the two photogrammetric surveys of a terrain comprising for example the slide movements, we can precisely determine for this slide, under conditions presented in the paper, the area of movements, the linear values of displacements, their velocity in any point photographed, as well as we may estimate qualitatively the rising of definite morphological slide forms such as swellings, fissures, wrinkles, outline of earth slide a. o.
