New algorithms for verifying the consistency between satellite images and survey conditions

Abstract

This paper is concerned with the problem of verifying the consistency of the Earth remote sensing data, including digital optical images and survey parameters metadata. The solution of the problem is based on analysis of specific numerical characteristics of the image that depend directly on the survey parameters, such as position of the Sun, position of the spacecraft, and orientation of the recorder. This paper presents two fully automatic calculation procedures (algorithms) of performing such analysis and making a decision about mutual consistency or inconsistency of the data.
