Methodology for creating a geoinformation-analytical system to monitor irrigated lands in the South-East of Kazakhstan
Аннотация
At present, the study of natural objects without modern information technologies is almost impossible. The use of GIS for monitoring spatial features of irrigation systems uncovers broad opportunities. The development of the organizational structure, the selection of the necessary software tools for the collection, storage, processing and analysis of semantic data integrated with spatial objects is an urgent task and has important scientific and practical value. The irrigated lands located in the southeast of Kazakhstan within the Almaty region are the object of research. Monitoring of these land salinization is carried out, including hydrogeological and hydrological observations and soil reclamation studies. The article discusses the methodology for creating a geographic information and analytical system to monitor irrigated lands, and describes its organizational structure. The content of the database, the composition of functional components, the basic properties and capabilities of laboratory processing and analyzes of field materials are described. The cartographic material component describes its basic properties, including properties intended for analysis of database objects and their spatial point analogues. Also, the possibilities for ArcGIS application modules to automate the process of constructing maps of the hydrogeological and reclamation conditions of irrigated objects, and the possibilities for automated calculation of areas in specified gradations of depth and groundwater salinity to assess the reclamation state of these lands are shown.
