Stages of photogrammetric processing of images from domestic satellite KazEOSat -1

Abstract

The number of fields using Earth remote sensing data is growing every year. There is a number of
advantages in using of remote sensing data for monitoring purposes than ground-based monitoring methods.
Photogrammetry, being one of the directions in remote sensing, is important in the correct interpretation and
analysis of remote sensing data.The work presented in this article was carried out as part of the implementation
of the scientific and technical program No BR 0533648 on program-targeted financing of applied scientific
research in the field of space activity from the Aerospace Committee of the Ministry of Defense and Aerospace
Industry of the Republic of Kazakhstan.The article discusses the main stages of photogrammetric processing
products - a digital elevation model, orthoimage and mosaiccreating, using images of the domestic KazEOSat-1
spacecraft.The possibility of a digital elevation model creation from multi-temporal images was tested.Due to
the fact that the relief is one of the main soil-forming factors, a regression analysis was carried out between the
variables - the values of the derived vegetation indices, and the heights of the relief according to the created
digital terrain model.The results of the analysis showed the effectiveness and necessity of using the DTM, built
from high-resolution images, as one of the sources of soil analysis.
