A comparative analysis of the remote sensing data, obtained by spacecrafts “Canopus-V” and “Aist-2D”, in terms of determining their actual spatial resolution – the smallest linear size of the terrain object that can be transmitted by the image. Within the researches of studied space imagery structural transfer properties the calculations of their general and local contrast for different types of underlying surface were performed. In particular, it was shown, that despite the smaller ground sampling interval (GSI), images, obtained by “Aist-2D”, are comparable in their structural transfer characteristics to the images of “Canopus-V” because of the greater blurring. However, “Canopus-V” images have a disadvantage – the artifacts due to direct solar reflection from smooth (mirror) surfaces, which “Aist-2D” images do not have. Basing on the obtained values of structural transfer characteristics and the requirements of the Instructions on photogrammetric work for digital topographic maps and plans creation, the mapping scale, corresponding the attainable accuracy of measurements, made by images, obtained by spacecrafts “Canopus-V” and “Aist-2D”, is determined. The conclusions about the comparability of considered space imagery structural transfer characteristics, the advantages and disadvantages in terms of their photographic quality, as well as the possibility of their use for mapping purposes are formulated.
