Latest Patents

One of Joseph A. Dean's latest patents focuses on optimizing offline map data updates. In this innovation, a system is designed to enhance the efficiency of offline map data updates. A server device within the system determines a metric for identifying map data objects based on their attributes. Subsequently, the server generates a quadtree that organizes these map data objects in nodes according to the identified metric. When an update to the map data is processed, the server creates update data that describes the changes for each node in the quadtree. This is achieved using a binary difference algorithm and/or a semantic difference algorithm, with the server selecting the algorithm that results in the smallest compressed size of the update data.
