Western Caspian Under Scrutiny

The significance of the Earth remote sensing from space for environmental studies can hardly be overestimated. The number of spacecraft, which routinely monitor the Earth’s surface, long ago has exceeded one hundred, and space data archives are measured with petabytes. With the increase in the number of spacecraft systems for the Earth remote sensing the quality and the resolution of the cameras are improving, reaching today 0.3 m. Today no less than 10 spacecraft are working with the spatial resolution better than 1 meter. However, there are many objects and processes, which can be monitored and mapped only with the data of centimetre resolution, with the combination of space-, air- and earth-based methods. Some of the phenomena and processes are still absent even on the large-scale maps, and the speed of their changes are poorly determined or completely unknown.
