Generation of magnified raster tiles using shift tiles to improve situational awareness

Kurzfassung

Maritime infrastructures are an important part of society in many aspects (safety and security, economy, environment) and therefore require special protection. From ensuring uninterrupted global trade and economic stability to safeguarding national security and protecting coastal communities, the comprehensive situational awareness picture plays a vital role in preserving the safety and security of these vital assets. To improve the operators' situational awareness, this work suggests a novel way to provide non-linear scaling of maps to enable legacy front-ends to provide a high resolution view of disconnected areas without requiring the user to change their viewport. So-called shift tiles are generated to scale different parts of given maps, allowing users to apply the desired scaling effect to any base map, regardless of the client being used.
