In the development process of many navigation frameworks and libraries, there were opportunities for introducing technology to wide spectrum of industries and services, as well for offices like firefighter departments. The main goal of every system is some process automatization that is needlessly done manually. On te other hand, every system has a certain risk percentage because it needs to provide support for every behaviour corner case in order to keep the process safe through its key moments. Firefighter departments were having a process of publishing new firefighter intervention by manually searching through paper cards which contained the fastest ways descriptions to reach the intervention destination and then carrying those cards to the vehicle up until now. Speed, accuracy and synchronization of firefighter units were the main factors in this process. Command center and vehicle on the intervention were communicating exclusively by radio connection. The main goal of whole new navigation system that was designed for this occasion was assigning intervention to vehicles automatization, enabling a currently active vehicles overview from the command center on the interactive map, displaying all needed information about the intervention to the device that is set in the vehicle (tablet). Goal of this application was uniquely and safely introduce a mobile device – tablet to the whole navigation system, displaying needed intervention route description in textual form, updating intervention location components on the device interactive map, sending an updated vehicle location to the server in real-time communication and enabling manual choosing of interventions and vehicles to the application user (firefighter on the ground).
