Latest Patents

Shiragami holds a patent for a spot searching device, navigation apparatus, spot searching method, spot searching program, and information recording medium having a spot searching program. This invention enables a partial update of data for spot search and enhances the efficiency of update operations. The data for spot search is structured by a plurality of spot search files containing points of interest (POI) data, a menu display file for displaying a search screen, and an area table. When a periphery search is conducted, a mesh code corresponding to a user-designated spot on the map is specified, and a search key is generated based on this mesh code. The relevant spot search file is then identified, allowing for the extraction of POI data related to facilities in the vicinity of the user-designated spot.
