Abstract
When map data is to be processed for display in a mapping or navigation apparatus, the application processor () of the apparatus first checks to see whether any existing data in a local cache memory () represents a similar map part to the new data that is to be processed. This is done by means of a similarity analysis (). If the map data already in the cache () is determined to be sufficiently similar to the map data that is to be displayed, new map data from a main map storage () is not loaded and processed, but instead the existing data in the cache () is processed for display of the map part in question. This has the benefit of a reduced system load, since already processed data does not need to be reloaded and reprocessed.
