dc.description.abstracten	The modern approach of evaluation of errors of surface digital photogrammetric survey is considered. The possibilities of taking into account the impact of error of the system of treatment of digital representation and parameters of digital matrix on exactness of determination of actual coordinates of points are considered. The methods of quality assessment identifying cracks on the results of photogrammetric surveys and the estimation accuracy of the length and area of cracks are offered. The calculations of theoretical step of scanning for different categories of cracks using laser scanners VZ- 400, VZ-1000, VZ-4000 of the RIEGL Company are executed. The order of determination of limits of area of laser scanning is reasonably depending on the parameters of cracks and technical descriptions of the laser scanner. According to the results of the calculations the method of determining the optimal parameters of laser scanning for different types of cracks is proved. Reasonable rational directions of the use of digital surface photogrammetric surveys and laser scanning in the study of multilevel fractured deposits of minerals are substantiate.	uk_UA
