Geoportal is a necessary component of the spatial data infrastructure or a means of web-mapping, widely used for educational purposes, one of the means of training specialists in the field of Earth sciences. Their classification is given, examples of geoportals of leading universities, including those included in the UNIGEO consortium, are given. Among them are Moscow State University named after M. V. Lomonosov, Tver State University and Belgorod State National Research University. Existing geoportals are used in laboratory classes, field practices, master classes, in the preparation of course and diploma papers. One of their advantages is the availability of remote sensing data and software for processing them for further use in the GIS environment when implementing GIS projects. Among the shortcomings is the «static» maps due to the lack of tools for managing the parameters of cartographic visualization. The overwhelming number of geoportals and their prototypes are visualization only and lacks the ability to search for data and the spatial metadata management system.
