Kazakhstani satellites acquired more than 220 million sq. km. of the territory in the flood period.

ASTANA. KAZINFORM - The most important source of information for flood monitoring in the regions of Kazakhstan is the data of the Earth's remote sensing space system (ERS SS), the correspondent of MIA Kazinform reports. 

The current flood situation on the territory of the country has been and still is difficult, since practically on the whole territory of the country and in the river basins snow reserves exceeded the norm by 1.5-2 times, emergency services in the regions report. 

Space monitoring of spring floods is conducted in regions with a high risk of flooding, located along the channels of large rivers, said Aydin Aimbetov, vice president on space technologies of JSC "NC "Kazakhstan Gharysh Sapary". 

So, for today, within the framework of concluded contracts, a space monitoring of the flood situation with emergency departments of Akmola, Almaty, Karaganda, Pavlodar, Aktyubinsk, Atyrau, East Kazakhstan, West Kazakhstan and South Kazakhstan oblasts was carried out. The ERS SS data for evaluating the snow cover and flood situation are provided to the customers of space monitoring on a daily basis, twice a day. In total, starting from March 1, 2017, the volume of transmitted space images during the flood period for state agencies and emergency services amounted to more than 220 million square kilometers. 

For efficiency and promptness of solving problems related to natural disasters, employees of the company "Kazakhstan Gharysh Sapary" developed a geoportal for providing access to Earth remote sensing data and analyzing the current situation on the basis of geoinformation technologies. The results of ERS SS space monitoring are displayed in real-time mode on the geoportals of departments of Emergency Situations of the RK regions, A.Aimbetov noted.

A geoinformation system (GIS) was created on the territory of the regions, containing cartographic and attributive data, which were used to create operational maps transmitted to the regional emergency departments. Kazakhstan's ERS satellites made a space imaging of the Aktyubinsk, East Kazakhstan, Akmola, Karaganda and West Kazakhstan regions, the territory of the city of Astana during the flood situation. And satellite images of the basins of the trans-boundary rivers Syr-Darya, Ili, and Chu were transferred online, space monitoring of the Koksarai counter regulator, glaciers of the Altai Mountains, Charvak and Shardara, and Vyacheslav reservoirs was done. 

According to the Emergency Department of the Aktobe Oblast, an information and analytical geoportal service was created in the framework of the agreement on the space monitoring of the flood situation in Aktyubinsk oblast to monitor the flood situation. The imaging was performed from the KazEOSat-2 spacecraft, where the zone of flooding and flooding of the rivers Ilek, Kargaly, and Sazd was shown.

Space monitoring of Lake Karasor in the Karkaralinsky region with the support of the KazEOSat-2 satellite revealed the zone of under-flooding of the railway section and allowed to determine the area of ​​the flooded territory. When the village of Zharly was flooded in the Karkaralinsky region, space images from the KazEOSat-2 spacecraft revealed the overflow of the Zharly River and the direction of the tide of water, noted in the emergency department of the Karaganda region. 

During the spring flood, the Aerospace Committee of the MDAI RK worked closely with the republican and local emergency services in order to prevent emergence situations, in particular, with the Committee of Emergency Situations of the Ministry of Internal Affairs, the Committee on Water Resources and RSE "Kazgeodesy" of the Ministry of Agriculture, RSE "Kazgidromet". 

Operative and actual photography from space allowed state bodies and emergency services to monitor water resources in all regions and take emergency measures whenever possible, said Aydin Aimbetov. 

Kazakhstan's ERS space system, which includes two satellites - KazEOSat-1 with a high spatial resolution of 1 meter and KazEOSat-2 medium spatial resolution of 6.5 meters, was accepted for regular operation in 2015, and a ground satellite control and processing complex of space images began operations a year earlier. Both ERS spacecrafts are currently operating in the normal mode, doing round-the-clock monitoring of the Earth's surface. 

Within one day KazEOSat-1 can acquire more than 220 thousand sq.km. and KazEOSat-2 up to 1 million sq.km. By the way, in the first year of regular operation ERS SS conducted a successful monitoring and forecast of seasonal floods and floods of the rivers of Kazakhstan. In 2015, using the Earth remote sensing satellite KazEOSat-1, an assessment was made of the scale of large flood zones in the Akmola region: the Nura River and adjacent settlements in the Karaganda region: the village of Kievka, Nurinsky District, Koktenkol Settlement, Shetsky District, Koktas, Tengizshilik settlements in the Karkaralinsky District .

Space days in Kazakhstan
International seminar “Space days in Kazakhstan”, which is organized by JSC “NC “Kazakhstan Gharysh Sapary” is devoted to the creation and operation of the Earth remote sensing space system of the Republic of Kazakhstan (ERS SS RK). The objective of the seminar: exchange of experience with the world leaders in ERS systems, informing of large public about possibility to apply products and services of ERS SS and HSNS of the Republic of Kazakhstan to solve industry problems of the economy of Kazakhstan.
