The result of the transformation of a satellite, multispectral image of the earth's surface, covered with a layer of snow, after applying the author's script using the custom script tool in the cloud browser Sentinel-Hub EO Browser, Sinergise.

An image conversion formula was applied using the Shadow Index (SI) algorithm and the Snow-covered Surface Detection (NDSI) algorithm.

Contrast enhancement of the microrelief image of the Earth's surface is made using the gain and gamma variables.

According to the author, the current terrain of this locality was formed in distant times as a result of a high-altitude explosion during detonation of a loose shell of a large cosmic body at collision with dense layers of the atmosphere, on the border of Vinnytsia and Cherkasy region.

This message concerns a complex object that has not yet been observed, was not interpreted, it is not registered in the international database of meteorite craters, or areas over which the destruction of the cosmic body with catastrophic consequences occurred, but is clearly evident on the current satellite images as a set of consequences of the effects of various physical factors of cosmogenic origin on the geomorphological changes in the microrelief of the surface of the indicated territory and accompanied by a picture of chaotic negative reversal background magnetization on the geophysical map of geomagnetic anomalies.

The surface microrelief of central Ukraine, distorted by the fall of the cosmic body due to various factors of mechanical impact:

- the formation of flat depressions with an arcuate breastplate due to the fall of the surface of explosive waves;

- formation of waves on the surface due to the Mach Stem effect;

- the formation of craters from the fall of solid fragments;

- formation of distorted valleys in the zone of maximum energy release during the high-altitude explosion of the loose shell.

The magnitude of the transformation of the terrain of the earth's surface, due to the fall of a large cosmic body, can only be realized when viewing satellite images.

Example of script used:

// Detection of surface microrelief details using

// winter images of a snow-covered terrain.

// The script visualizes Earth surface in False Color from Sentinel-2 data.

// Viewers: Sentinel-Hub Playground or EO-Browser

// Remark: Make sure to enable "Atmospheric Correction" or use S2L1A image type
