This article explores the implementation of digital geoinformation systems (GIS) models in desktop applications using the Qt framework. This highlights the importance of GIS technologies in various fields and the need for powerful desktop applications capable of efficiently processing spatial data. Integration of GIS models into Qt-based applications provides a number of advantages, such as efficient data management, spatial analysis and user-friendly interfaces. The article highlights the cross-platform compatibility of the Qt framework, which allows you to deploy GIS-enabled applications on multiple operating systems. In conclusion, it should be noted that the introduction of digital GIS models into desktop applications developed using the Qt framework provides significant benefits to both developers and users. This allows users to access, analyze and visualize geospatial data, thereby improving decision-making processes. The combination of GIS and Qt capabilities allows developers to create reliable and user-friendly applications to meet the growing demand for spatial data management and analysis tools.
