1. A computer system for managing mobile objects comprising:
- one or more processors;
one or more computer-readable memories;
one or more computer-readable storage devices; and
program instructions stored on at least one of the one or more computer-readable storage devices for execution by at least one of the one or more processors via at least one of the one or more computer-readable memories, the program instructions comprising;
a subsystem for managing a map of a geographic space including a route, wherein managing the geographic space comprises managing a mobile object, and wherein the map of the geographic space comprises a first update block and a second update block, wherein the first update block and the second update block define a boundary in which an update to the map occurs, and wherein the first update block and the second update block share a common boundary;
an update manager for managing updates to the map of the geographic space, wherein to prevent a load imbalance the update manager changes the common boundary between the first update block and the second update block based on an extent to which the first update block is updated, and wherein the extent to which the first update block is updated comprises an attribute selected from the group consisting of an update frequency, an update data amount, a number of update files, and an update data loading time of the map corresponding to the first update block, wherein the update manager divides the first update block into a plurality of update blocks if the update frequency that the first update block is updated exceeds a limit value.
