Abstract

The article is devoted to the issues of evaluating errors of remote measurement of thermokarst lakes characteristics in the Arctic zone using high resolution Kanopus-V images. Remote investigations were carried out at 98 test sites, located in the territory of the cryolithic zone of Western Siberia and north-east of the European part of Russia. To describe the tortuosity of lake boundaries were used the spatial object shape index, accepted in cartography, which is calculated based on the results of lake area and perimeter measurements using satellite images. A histogram of the distribution of the lakes coastal borders tortuosity degree in a wide range of their sizes from 50 m2 to 20 ha was built. The analysis of the histogram showed that the distribution of tortuosity degree corresponds to the theoretical log-normal law. For investigation of errors of remote measurement of lake parameters the technique of construction of random flat geometrical figures (model objects) with given value of tortuosity degree is offered. Relative error of object area measurement using space image is studied. Influence of object boundaries smoothing on errors of remote sensing of areas and tortuosity of boundaries is studied. It is shown that smoothing practically does not affect the errors of area measurement and has a significant impact on perimeter and tortuosity measurements.
