Satellite satellite mapping is developing in Turkmenistan

Internet

Turkmenistan, like the rest of the world, celebrated Cosmonautics Day and honored the feat of the first earthling in outer space. This year, six decades have passed since the first human spaceflight - Yuri Gagarin conquered the cosmic expanse on April 12, 1961.

It became a significant milestone in the history of human development, having stimulated the development of a whole range of branches of science, economy and technology and caused the appearance of completely new spheres of human activity. One of them was space cartography, which allowed researchers to get reliable information about the features of the Earth's surface without the need to travel long distances and costly expeditions. Now geographers and landscape scientists also have an opportunity to carry out their activities not in the field, but in comfortable laboratory conditions.

Turkmenistan, like other countries, actively uses space imaging capabilities to study the Karakum and other hard-to-reach areas within the country.

The accuracy of terrain recognition at this stage exceeds 90%. Surveyors are able to carry out the identification and study of three degrees - modern, historical and paleographic - of slices of evolution of various territories. This will make it possible to know not only their past and present, but also to make a fairly accurate prediction of the future.

The territory of Turkmenistan is covered with space imagery of various scales and types. Obtained images are used in compiling maps, intended not only for economic activities, but also for implementation of activities aimed at protection of natural environment.

As a result of cartographic surveys we received detailed large-scale maps and colorful atlases showing the results achieved by Turkmenistan during the 30 years of its independence. In particular, large industrial facilities such as the gas-chemical complex in the territory of Kiyanly village, the International Sea Port in the city of Turkmenbashi, new installations of the Turkmen refinery and others can be clearly seen on the maps.

At the moment, researchers are working together to study and map the dynamics of desert geosystems as part of the fight against desertification. For this purpose, a three-step scheme is used - the previous state, the current state as well as the predicted state are considered.

The test site located between Ashgabat and Bakhardok was chosen as the place for investigations. Its area is about 10 thousand square meters. The area is of interest both in terms of science and in practical terms. There are not only modern but also rather ancient landscapes with a direct connection to many archaeological monuments. There are also a number of new buildings, settlements and the development of new lands.

Researchers obtain data using repeated space images taken by Landsat 7 eTM+ and Landsat Mapping8 satellites in 1987, 1999, 2005. Their analysis is carried out by the method of "reverse indication", comparative-geographical and remote methods. This made it possible to map the landscape-ecological zones and divide the periods of the Holocene epoch. As a result, 5 historical-geographical slices have been defined. They allow to restore the former contour of the geo-ecological situation, to map it and to predict possible changes.

Other thematic maps are expected to be created in the future, as well as the work on making ecological passports of landscapes will be continued. This will be facilitated to a great extent by the scheduled launch of the Turkmen satellite into the sun-synchronous orbit in the nearest future, designed specifically for land surface imaging.
