The article discusses aspects of the application of geoinformation systems in the tourism business. The rational use of tourism resources in the modern world is becoming an increasingly complex and urgent task. Software in geographic information systems enables people engaged in the tourism business to easily integrate and use available sources of tabular and cartographic information to improve the quality of decisions. Modern geoinformation technologies can be used in organizing and stimulating tourist activity. The main problem in this activity is the lack of information about the area in which the organization of tourism is carried out. We must take into account the terrain, the availability of recreation areas. If tourism is organized, then you need to know the locations of hotels, as well as attractions in the area of the route. If we are dealing with individual travel, it is necessary to know the schedule of transport, rates of hotel rooms, etc. Tourism is one of the industries that have used GIS in their development. The result was the mass application of GIS technology in solving many current and strategic tasks of this area of activity. It should be noted that geoinformation systems will help not only the organizers of the tourism business of the region, but also end users. The tourism business requires improving the quality of management and monitoring of natural and cultural resources, improving the perception of geoinformation in an accessible form for the user. The application of geoinformation technologies for the development of hiking, water and mountain tourism is discussed. Specific geoportals developed for the areas of the Caucasian State Biosphere Reserve, East Kazakhstan region, Astrakhan region are considered. It can be noted that recently there has been an active integration of geoinformation systems and tourism business, which brings great benefits to both tourism and geoinformatics.
