But it is convenient to study this kind of information at home, sitting at the computer, and in this case it is difficult to trace the connection between the historical and modern infrastructure of the city. Other disadvantages of this method are also obvious: a lot of time spent searching for the necessary information, lack of access to archival data for each of the objects, especially during a walk. In the "KharkivHeritage" project, we tried to solve these problems and provide smartphone or tablet users with real-time access to photos and text information on more than 120 city objects (about 1,300 illustrations).
