Methodology of measuring processes and evaluation of water resources of the Republic of Kazakhstan

Abstract

The article highlights the methodology of evaluating the changing processes and water resources of the Republic of Kazakhstan with the help of geoinformation technologies, determining their dynamic parameters based on thematic satellite data processing methods and techniques for theoretical and applied purposes. A review of space imaging systems with different technical characteristics was carried out. A technological scheme for making precision mosaics using high-resolution optical electronic space imagery is proposed; this is supplied with mosaics composed of LANDSAT space imagery of the Ertis river basin. A schematic map has been developed showing the water basins of transboundary rivers in Kazakhstan and neighbouring countries with a list of cartographic layers, objects and information, including administrative territorial divisions and terrain (contours, heights, forms of relief), as well as the structure of the GIS database.
