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.

Map information processing apparatus and map information processing method

A map information processing apparatus includes a map information storage unitfor storing map information which is separated into multiple layers, a layer-to-be-updated-with-addition determination processing unitfor determining one or more layers which are to be updated with addition of an unregistered road which has been detected during travel of a vehicle, and an unregistered road adding and updating unitfor adding the unregistered road to the map information storage unit to update the map information with the addition being aimed at the one or more layers determined by the layer-to-be-updated-with-addition determination processing unit.

Map information processing apparatus

A map information processor includes a map information storage unitfor storing map display information including a set of pieces of mesh-by-mesh map information managed on a mesh-by-mesh basis and including road information, background information, and in-mesh image information, an image processing unitfor generating a map image on a basis of image data included in the road information, the background information, and the in-mesh image information included in the mesh-by-mesh map information read from the map information storage unit, and a display devicefor displaying the map image generated by the image processing unit.

Map information processor and data structure of map information

A map information processing apparatus is disclosed. The apparatus includes a processor for calculating a vehicle position; a data generation unit for generating traveling locus data on the basis of the calculated vehicle position when the vehicle position deviates from a road; a registration unit for registering the traveling locus data generated by the data generation unit in a temporarily registered road list as a temporarily registered road; an operation unit for selecting one of temporarily registered roads registered in the temporarily registered road list; and an official registration unit for registering the selected temporarily registered road in an officially registered road list as an officially registered road in accordance with an instruction from the operation unit, generating road data on the basis of traveling locus data relating to the temporarily registered road, and adding the generated road data to a map data stored in a map data storage unit.

A map information processing apparatus includes a road matching means () for comparing the road data with current position data to carry out map matching, an input unit () for inputting both a specified detection start point and a specified detection end point, an unregistered road detection means () to which both the specified detection start point and the specified detection end point are inputted, for detecting, as an unregistered road, a section between a detection start point and a detection end point of the unregistered road which are acquired on the basis of either the map matching carried out by the road matching means or the result of comparison between running track data and the road data, and a road data generating means () for generating road data corresponding to the detected unregistered road and storing the road data in a map data storage means.

A map information providing system has a map information providing apparatusand an onboard information terminal. The map information providing apparatusselects a road represented by the coordinate point string data indicating a newly established road in accordance with distribution request information obtained from the onboard information terminal, and distributes the distribution road information containing the coordinate point string data about the road selected to the onboard information terminal. The onboard information terminal obtains the distribution road information containing the coordinate point string data from the map information providing apparatus, and generates, in the same format at least in part as the map information, road data for adding a new road to a road network represented by the map information stored in a map information storing section from the coordinate point string data contained in the distribution road information obtained, and generates new map information from the road data and map information.
