GIS technologies allow an analyzis of large data sets at the lowest cost. To date, when forming a network of secondary schools, almost no geographic information systems have been used. GIS plays a special role in the study of transport and walking accessibility to GSEI. The article analyzes the theoretical, methodological and practical problems of using geographic information systems in studies of walking accessibility to general secondary schools of Chernivtsi city territorial community and describes the general secondary education institutions of the studied community. Based on geoinformation systems developed in Open Route Service and QGIS, the areas of the community with the best and worst walking accessibility to secondary schools were identified, which is certainly of great practical importance in creating pivotal institutions, their service zone and overcoming the problem of overcrowding in some schools. The most convenient location of the general secondary education institutions of Chernivtsi city territorial community was observed in the central part of the city, as well as in microdistricts Prospect and Boulevard, where there is a fairly dense arrangement of general secondary education institutions. There are also areas in the community that are outside the 2-kilometer walking accessibility zone and require transportation for students. Such areas are the Shantsi, Tsetsyno and Slobidka and Rohizna microdistricts, which have a cottage type accommodations. In general, most of the community is within walking accessibility. An important aspect of the location of GSEI is the availability indicator, which ranges 0.2 to 0.81. The average rate of accessibility to GSEI in the Chernivtsi city territorial community is 0.65. It should be noted that in the community there is a relevant problem of providing students with places in GSEI in those areas, where today the construction of new residential areas is actively carried out, while educational institutions are not expanding and not being built.
