Creation of anaglyphic relief maps in GIS with open object code

To date, no one will be surprised by 3D technologies, for users, monitor screens with visualization in the form of three-dimensional 3D images have become common and familiar. There are many ways to add volume to still and moving images. Accordingly, technologies for creating three-dimensional graphics are extremely diverse in nature, allowing you to model virtual objects and create images based on them. At the same time, various visualization systems of numerous three-dimensional (3D) models (including digital terrain models (DEM)) using stereo effect are the most effective and characterized by the maximum degree of clarity. This determines the purpose of this work – to study and analyze the possibilities and features of creating anaglyphic relief maps using free software for geographic information systems with open object code. Three-dimensional geo-images of the relief were created by implementing the anaglyphic method on the example of the territory of the Republic of Mordovia. The relevance of the presented research is determined primarily by the fact that the active and widespread introduction of various variants of 3D geo-images into our daily life and the practice of scientific research simultaneously reveals the presence of a number of problems related in one way or another to technologies and means of obtaining and perceiving them. The theoretical aspects and modern methods of creating anaglyphic relief images using various GIS products were studied, their disadvantages and advantages were revealed. The results of the work confirm the possibility and accessibility of using the GIS functionality with open object code to create anaglyphic geo-images. Using the functionality of the open GIS SAGA and QGIS, a series of relief anaglyph maps for the territory of the Republic of Mordovia was obtained. The results of the research performed, the data obtained and the author's materials created confirm the need and identify possible ways to improve the overall technological scheme for creating anaglyphic maps and plans. The given technological schemes for the creation of anaglyphic geo-images and the obtained materials can be used in organizing and conducting further studies of the features of the relief of the Republic of Mordovia.
