This paper explored the concept of geographic information systems and their importance for tourism. The term GIS is defined as a computer tool for creating and analyzing geographic objects or phenomena occurring in the area.. We set up two hypotheses: tourist offer is familiar with the functionality of GIS systems and applications based on GIS are useful for the development of tourism. After studying different scientific papers, case studies and articles, both hypotheses were confirmed to some extent.. At the end of this study it was concluded that GIS systems play an important role in enhancing the tourist offer and have great significance for the development of tourism and further development in the future, and applications based on GIS are useful for the development of tourism and tourist attractions.
