Abstract

This article discusses cartographic work on creating maps of the territory of the dry bottom of the Aral Sea using conventional signs and showing the bottom with contour lines. As the sea dried up, the need arose to create topographic maps of the resulting land based on aerial and satellite images. In addition to the relief, it was necessary to show on the map the types of soils, sands, and types of vegetation. As a result of the retreat of the sea, it is necessary to identify the dynamics of the development of the land bottom and monitor the relief, how it changed in connection with this process. For such work, it is necessary to use satellite images using GIS technologies, as well as data from remote sensing of the Earth and create a digital model of the relief of the dried bottom of the Aral Sea. Based on this digital terrain model, it is possible to predict the state of the area in order to develop measures to increase the level of environmental stability and the ability to plan for the future.
