Abstract
An information processing apparatus that acquires estimated altitude data corresponding to a position based on detection information detected by a sensor at or near the position, and corrects altitude data associated with the position based on the estimated altitude data.
Claims14
An information processing apparatus comprising:
- circuitry configured to:
- acquire estimated altitude data corresponding to a position based on detection information detected by a sensor at or near the position;
- compare the estimated altitude data with an altitude data received from a storage unit to determine if there is a difference between the estimated altitude data and the altitude data;
- and
- generate correction information based on the difference between the estimated altitude data and the altitude data,
- wherein the detection information is acceleration data detected by an acceleration sensor at or near the position, and
- wherein the circuitry estimates the altitude data based on a change of the acceleration data over time.
