Abstract:
The results of fine quality indicators assessment for images, obtained with various aerial surveying systems for mapping purposes are presented. The values of parameters that characterize technical conditions, technical parameters of airborne imaging and technologic settings for imagery postprocessing, natural conditions of aerial surveying are determined. The author presents a comparative analysis of fine quality indicators assessment both for photos, the quality of which was found to be satisfactory as production technical control results and those rejected due to some relevant indicators (haze, blurring, etc) and accepted unsuitable for creating cartographic products based on them. It is shown, that some quality indicators, such as spatial resolution, sharpness and the degree (standard deviation) of random noise, are advisable to be determined at performing factory calibration of aerial cameras and included in certificate as well as other calibration parameters as metrological characteristics of the obtained imagery. Acceptable values of fine quality indicators, obtained during joint analysis of previous theoretical researches results and experimental verification, based on images, obtained by various aerial surveying systems for mapping purposes were generalized and recommended during the research.
