The goal of research is development of scientifically sound methods and automated information technologies for calibration and validation of satellite Earth observation data to ensure their reliability, increase accuracy, competitiveness and suitability for use in scientific and applied problems. Research methods: methods and information technologies of big data analysis, methods of machine learning, methods of cloud information processing, regression analysis, correlation analysis. The obtained results: - methods and models of biophysical parameters calibration are developed and their validation based on the in-situ data is carried out; - an approach for satellite products validation based on in-situ data and photointerpretation data has been developed; - the method for spectral research on archival satellite data and selection of test objects suitable for post-launch radiometric calibration of satellite optoelectronic sensors was developed, created a corresponding geoinformation layer for the territory of Ukraine and created the software for its implementation; - was developed and tested the method of post-start radiometric calibration of optoelectronic sensors of space observation of the Earth on the basis of the proposed differential method of estimating the spectral reflection coefficient of test objects according to in-situ data using the atmospheric transmittance calculated from the world network AERONET data; - developed and implemented procedures for subpixel processing of radar satellite data to increase their spatial resolution and showed the possibility of increasing the spatial resolution of radar images of fixed objects according to Sentinel-1 to 1 - 2 m.
