A method for implementing visualization of public welfare activities includes: displaying to a target user a map of a geographic region for carrying out a public welfare activity in response to the target user's selection, wherein the map comprises a first geographic location associated with a first icon indicating that the public welfare activity has been carried out at the first geographic location and a second geographic location associated with a second icon indicating that the public welfare activity is able to be carried out at the second geographic location; when a relationship exists between the target user and a public welfare activity participant user that has carried out the public welfare activity on the map, displaying on the map user information of the public welfare activity participant user; updating the second icon to be a first icon in response to the target user's selection on the second icon.

The present application includes a search route processor that calculates a plurality of search routes between locations of a plurality of searchers belonging to a predetermined area and a search target based on position information of the search target acquired from a position information terminal held by the search target, and a plurality of portable terminals that is held by the plurality of searchers and displays the plurality of search routes calculated by the search route processor and personal information that identifies the search target.

A navigation information device is provided with a position acquisition unit for acquiring a position information of its own ship, a memory for storing display settings corresponding to a waypoint that is a via point on a planned route, and a display processing unit for performing generation processing for generating a screen in which the position information is superimposed on a chart, and performing change processing for changing display settings to display settings corresponding to the waypoint based on a positional relationship between the position information and the waypoint.

An object of the present invention is to obtain a host vehicle position estimation device capable of estimating a highly reliable traveling road. The present invention relates to a host vehicle position estimation device (100) that estimates a position on a map of a host vehicle using information of an autonomous navigation position calculated based on vehicle information (102) and output of an inertial sensor (101), and information of a positioning position acquired from a positioning satellite, and corrects the autonomous navigation position to a position of a road on the map at predetermined travel distance intervals when the information of the positioning position is unavailable. The host vehicle position estimation device (100) includes a correction determination unit (12) that determines whether or not to perform the correction based on a position and an orientation of the host vehicle traveling on the road.

Systems and methods for indexing geological features are disclosed. In one embodiment, a method for indexing geological features includes accessing a database storing a plurality of map objects that originate from documents. Each map object includes a map defined by a geographical boundary and a text caption. The method includes, for each map object, determining a plurality of geohashes within the geographical boundary, and includes, for each map object, comparing terms of the text caption with a list of geological keywords. For each map object, the method includes identifying one or more geological noun phrases within the text caption that match one or more geological noun phrases of the list. The method includes determining, for each geological noun phrase, one or more geohashes associated with the geological noun phrase and, for each geohash, determining a frequency that the geohash is associated with the geological noun phrase.

The present invention provides an information provision system that provides information to a driver of a straddle type vehicle, the system comprising: an acquisition unit configured to acquire information on a course of the straddle type vehicle; a specification unit configured to specify an attention portion to which attention of the driver should be paid in the course acquired by the acquisition unit; and a notification unit configured to notify the driver of the attention portion specified by the specification unit, wherein the specification unit is configured to specify the attention portion based on inclination information indicating an inclination on the course of a reference vehicle that has previously traveled on the course, and specify the attention portion based on a difference in a travel route on the course between the straddle type vehicle and a four-wheeled vehicle as the reference vehicles.

A server device stores on a storage unit an advanced map database which includes feature information associated with a feature. The server device receives, from vehicle mounted devices equipped with external sensors which measure features, difference information indicative of a difference between feature information and the actual feature corresponding to the feature information. In accordance with the degree of reliability which is calculated based on a plurality of the difference information, the server device sends to the vehicle mounted device a raw data request signal for requesting the transmission of raw data which is measurement data of the actual feature.

In some implementations, a computing device can provide a map application providing a representation of a physical structure of venues (e.g., shopping centers, airports) identified by the application. In addition, the application can provide an inside view that includes the physical layout and geometry of the venue's structure as well as the location, structure and layout of points of interest (e.g., stores, security check points, restrooms) within the venue. The views become more detailed as the user zooms into the venue to reveal points of interest and to give the user a feel for traversing the venue.

Superimposed-image display devices and programs display a guide image providing a guidance of information to a driver of a vehicle such that the guide image is superimposed on a view ahead of the vehicle and is visually recognized. The systems and programs obtain three-dimensional map information that specifies a three-dimensional shape of a road and a structure nearby the road and arrange the guide image in the three-dimensional map information, based on the three-dimensional shape of the road and the structure nearby the road. The systems and programs obtain a shape of the guide image that is visually recognized from a position of the driver in the three-dimensional map information and display the guide image having the obtained shape.
