摘要： A trajectory display device includes: a display element; a current position detector; a memory for storing the current position successively; and a position determination unit for determining a plurality of certain actual distance trajectory points and a plurality of direction change points based on position data stored in the memory. The certain actual distance trajectory points are arranged at every actual distance defined by a scale of a map. The moving body changes a moving direction at each direction change point. The display element displays the trajectory including the certain actual distance trajectory points and the direction change points, which is overlapped over the map.

摘要： In a course of updating old map data on a hard disk drive to new map data, a low-priority portion of the old map data that has less importance/necessity is deleted to create a vacant area, and a high-priority portion of the new map data is copied to the vacant area as an update of the map data. Then, the high-priority portion of the old map data is deleted to create another vacant area, and a low-priority portion of the new map data is copied to the vacant area. During the update of the map data, restrictions on the usage of the map data are avoided at all efforts by having the high-priority portion of at least one of the new map data and the old map data maintained on the hard disk drive, while maximizing the utilization of storage resources in a map data management apparatus.

摘要翻译： 在将硬盘驱动器上的旧地图数据更新为新的地图数据的过程中，删除重要性/必要性较小的旧地图数据的低优先级部分以创建空白区域，并且高优先级部分 作为地图数据的更新，新的地图数据被复制到空白区域。 然后，删除旧地图数据的高优先级部分以创建另一个空白区域，并且将新地图数据的低优先级部分复制到空闲区域。 在更新地图数据期间，通过使新地图数据和旧地图数据中的至少一个的高优先级部分保持在硬盘驱动器上，在所有努力下避免了对地图数据的使用的限制，同时 最大化地图数据管理装置中的存储资源的利用。
