The article presents the problem of a database access in the navigation systems. The authors were among the main creators of the prototype navigation system for the blind - “Voice Maps”. In the implemented prototype only exemplary, limited spatial data were used, therefore they could be stored in the mobile device’s memory without any difficulties. Currently the aforementioned system is being prepared for commercialization - the resulting increase of spatial data scale and complexity required a modification of the way the data are stored and accessed. Consequently, the decision was made to maintain a central spatial database. After that modification, the mobile application fetches necessary batch of spatial data remotely from the central server. The authors present the advantages and disadvantages of this new approach.
