The positions of the border node and the opponent border node are moved to target points so as to accord with each other, thereby reducing a possibility to worsen an appearance of a map as a result of the update of the unit area of the map data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Map data update apparatus","description":"In a vehicular navigation apparatus, when map data of a unit area is updated, it is determined whether a border node contained in an adjoining unit area which adjoins the updated unit area is separate","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8537162","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
