Abstract

The objective of the present invention is to provide a relative location data correction apparatus, a relative location data correction method and a relative location data correction program that can cope with the shifting of a relative location between different digital map databases, and can accurately display a desired point.A relative position information correction device, a relative position information correction method, a relative position information correction program capable of absorbing a relative position shift between different digital map databases and correctly displaying a desired point. The relative position information correction device includes a transmission side device (100a) for transmitting to a reception side device (200a) event information such as an accident and traffic jam created according to the digital map database (101) and the reception side device (200a) for displaying an event occurrence point on the map indicated by the digital map database (207) according to the event information received from the transmission side device (100a) and performing position correction when displaying the event occurrence point. The transmission side device (100a) calculates the total length of the road section and transmits shape vector expression information including this total length to the reception side device (200a). The reception side device (200a) calculates the total length of the road section so as to correct the relative position of the event occurrence point by using the two total lengths.

Description

Technical field

[0001] The present invention relates to a relative position information correction device, a relative position information correction method, and a relative position information correction program, which are used to absorb information in different digital places. Graph database The relative position offset between and is used to accurately display the desired point. The present invention also relates to a shape vector generation device, a shape vector generation method, and a shape vector generation program, which are used for digitally Graph database When a shape vector indicating a predetermined road section is generated from the map data stored in the map data, a feature node is set in the shape vector. Background technique

[0002] Car navigation systems used in vehicles, for example, have the following functions: use digital ground Graph database And based on the location data obtained from the information received by the GPS receiver, to display a map of ...
