Abstract
The present invention has an object to provide a technique capable of appropriately determining whether a vehicle has entered a facility range. A navigation apparatus includes a storage, a position detector, and an entry determining unit. The storage stores map information including a facility range. The position detector detects a position of an own vehicle. The entry determining unit determines that, in a case where the position of the own vehicle detected by the position detector has entered an entry determination range associated with the facility range, the own vehicle has entered the facility range.

9. A map information processing apparatus comprising:
-
a processor to execute a program; and a memory to store the program which, when executed by the processor, results in performance of steps comprising, acquiring map information including a facility range, acquiring a position of a vehicle using a vehicle position detector, determining that, in a case where the position of the vehicle acquired has entered a predetermined first range associated with said facility range, said vehicle has entered the facility range, and storing, between when it is determined that said vehicle has entered said facility range in said determining and when the position of the vehicle acquired exits said first range of the facility range, a determination history of said entry, wherein whether a current point of time is at a midpoint of a period between when it is determined that said vehicle has entered the facility range in said determining and when the position of the vehicle acquired exits said first range of the facility range is determined based on whether the determination history of said entry is stored in said storing.
