The general field of the invention is that of synthetic vision systems for a vehicle, said vehicle having a particular navigation direction. The system in accordance with the invention includes at least: a cartographic database representative of the terrain travelled over by the vehicle, means for geolocation of said vehicle, electronic means for computing a representation of the principal parameters of said vehicle; graphic generator means for generating a three-dimensional synthetic representation of said terrain; and a display device displaying said three-dimensional synthetic representation in a particular field of view (FOV) and in a particular display direction, means for modifying the display direction to a direction different from the particular navigation direction of the vehicle, said modification means being manual or automatic, the display direction then being a function of a piloting or navigation parameter.

An information provision system includes a terminal device, and an information provision device that can communicate with the terminal device. The information provision device includes a communicating section configured to communicate with the terminal device, a head count information managing section configured to manage current head count information for each position, and a crowd information generating section configured to determine a position for making a notification display based on the managed head count information, and generate crowd information containing information of the determined position, and a transmission control section configured to transmit the generated crowd information from the communicating section to the terminal device. The terminal device includes a communicating section configured to communicate with the information provision device, and a control section configured to execute display of a map image on a display section, and execute a display based on the transmitted crowd information on the map image.

Technology for generating high perceptual-quality distance cartograms, which use geo-contextual anchors to avoid topological violations, is disclosed. A system can calculate the travel times between a selected origin of the graph, and other locations within the graph based on a graph describing the transportation network within a region (e.g., an urban setting) and data describing travel conditions. Other nodes are then shifted such that the distances between them and the origin are reflective of the travel times between them. When a shifted node violates the topology of the transportation network, which hamper a user's ability to utilize a map due to disruptions in the physical relations between adjacent nodes and map overlaps, the node is instead placed at an alternate location that does not result in a violation. A graphical projection, or geo-contextual anchor, is then generated that indicates where the node would be located but-for the violation.

In order to create an accurate map with a simple operation, the map creation system includes: a relative position acquisition means to measure distances and directions from a sensor to points on a surface of an infrastructure or an object and to create point cloud data in a relative space with the sensor at the center thereof; a sensor position acquisition means to measure the position and the attitude of the sensor and to create sensor position data; an absolute position calculation means to calculate position information of the point cloud in the absolute space on the basis of the point cloud data in the relative space and the sensor position data; a direction-vector calculation means to obtain a direction vector from the sensor to each point of the point cloud in the absolute space on the basis of the point cloud data in the relative space and the sensor position data; an area detection means to extract points composing a plane area on the basis of the position information and the direction vectors of the point cloud in the absolute space and to obtain the area outline on the basis of the distribution of the extracted points; and a drawing means to draw a picture representing the detected area outline with a line.

A system and method for stadium seating selection provides a computer-implemented interactive website and software application that allows a user to determine which stadium seats are in the shade or sun at a given time during an outdoor event and to view a stadium's seating in relationship to the sun and shade according to the date and time of day. The website or app displays a diagram of the stadium of interest with seat or section numbers and shows the orientation of the sun and a progressively moving shade shadow corresponding to the date and time of day. The shade and sun information may also be provided in text or audio format.

A map generation system includes: an extraction unit that collects vehicle speed information, which includes at least a speed, acceleration, and deceleration, from a vehicle and that extracts rapid deceleration information, which includes a first location where a rapid deceleration event satisfying predetermined conditions has occurred, and a traveling direction of the vehicle at the time when the rapid deceleration event has occurred from the collected vehicle speed information; a storage unit that stores map data; a division unit that generates mesh map data by dividing the map data stored in the storage unit into a plurality of meshes in a predetermined size and a predetermined number of divisions; and an estimation unit that estimates a location that requires caution when the vehicle travels therethrough, as a caution-required place, based on the rapid deceleration information extracted by the extraction unit and the mesh map data generated by the division unit.

A computer server prepares application-specific map data responsive to a request from a client device. The application-specific map data includes map feature data and label data which itself includes information that specifies one or more zoom levels for which the label information is appropriate to display. When generating the label data, a type table that designates label style information by feature type and by zoom level may be used at the server. The map feature data may also include a relative rank for each feature that is passed to its corresponding label. The display order allows the map client, when generating the map, to select the most appropriate labels to display when the display of all possible labels would cause clutter or otherwise violate label display rules.

An information terminal transmits present position information and acceleration information to a server device. The server device receives the present position information and the acceleration information of the information terminal, generates congestion prediction degree using the acceleration information, associates the congestion prediction degree with map data such that the congestion prediction degree can be displayed on a road map, and transmits association information indicating the association. The information terminal displays the congestion prediction degree on the road map on the display device using the association information transmitted from the server device.
