The National Space Center of Kazakhstan (Қазақстан Ғарыш Сапары) is currently implementing digital bathymetric surveys that provide detailed riverbed mapping data, Berik Rakhymzhanov, Deputy Director of Space Remote Sensing (SRS), informed a correspondent of Kazinform IAI.

The company has received new equipment - a marine autonomous drone that can be operated remotely. This equipment is an Apache 3 unmanned hydrographic vessel, which was acquired under the program of targeted funding of the Ministry of Education and Science of Kazakhstan called "Scientific and Applied Basis of Integrated Flood Management with the Development of an Algorithm for their Prevention for the Basin of Large Rivers of Northern, Central, and Eastern Kazakhstan".

"This type of equipment for hydrographic surveys is used for the first time in Kazakhstan, and this method can be referred to as "precision hydrology". The collected data is characterized by reliability, accuracy, and high efficiency of its acquisition. Now we will be able to use it for editing high-resolution digital elevation models, in combination with radar polarimetry to develop methodologies for determining snow cover density, perform digital bathymetry, complete our GIS data analysis and provide flood modeling with a high level of detail," said Berik Rakhymzhanov.

With this Apache 3 marine drone procurement, the Kazakhstan National Space Centre (Қазақстан Ғарыш Сапары), which operates the national remote sensing space system, has gained new expertise using USVs for underwater surveys, which qualitatively enhances the research capabilities in remote sensing, geoinformation systems analysis and hydrology in the Republic of Kazakhstan.
