An apparatus for providing marine information is provided including a user interface, a processor, and a memory including computer program code. The memory and the computer program code are configured to, with the processor, cause the apparatus to generate a sonar image based on sonar return data received from an underwater environment, determine a location associated with the sonar return data based on location data received from one or more position sensors, and render a nautical chart on a display. The computer program code is further configured to cause the apparatus to receive a user input on the user interface directed to a portion of the display in which the nautical chart is presented, and modify presentation of the nautical chart such that the portion of the display presents the sonar image in response to receiving the user input.

A system and method include generating, by a map labeling control unit including a processor, label candidates for areas of an airport map, evaluating, by the map labeling control unit, the label candidates to determine positions of labels for the areas of the airport map, and determining, by the map labeling control unit, different sets of labels to display for different views of the airport map.

Aspects of the disclosed invention relate to alignment of standard definition (SD) maps and high definition (HD maps) which may come from different sources. Responsive to input of a destination, a route to that destination may be defined, and SD map waypoints generated from that defined route. A graph may be generated from the HD map. The waypoints may be matched with nodes and edges in the graph. One or more edges may constitute a segment in the HD map. A plurality of segments are identified to match the route.

A user can easily select a live camera image of a desired position on a map. A mobile terminal 30 displays a map on which, from among object images of a plurality of types, an object image of a type having an attribute of an image target of an image capture device disposed at a predetermined position is overlaid at a position corresponding to the predetermined position, receives selection of the displayed object image, and displays both the map and an image captured by the image capture device corresponding to the selected object image on one screen.

A computer implemented method for three-dimensional volumetric indoor location geocoding relative to a geographic location is provided. The method includes: creating a three-dimensional representation of the geographic location; notionally subdividing the three-dimensional representation into an array of discrete elements; receiving an address and converting the address into geographic coordinates; querying the array of discrete elements representing the geographic location; determining a list of all discrete elements with at least one of a matching address and sub-address element attribute; generating a notional minimum bounding three-dimensional polygon containing the matched discrete elements with the at least one matched address and matched sub-address element attribute; determining a list of geodetic coordinates defining the minimum bounding three-dimensional polygon; and presenting the list of geodetic coordinates defining the minimum bounding three-dimensional polygon.

Disclosed is a system method for aligning a plurality of electronic map data, which includes the steps of obtaining an electronic map file, defining an area of interest on the electronic map file, selecting a predetermined datum and providing the electronic map file in the predetermined datum. Also disclosed is a land yield method including the steps of obtaining an electronic map, storing the electronic map in a computer readable medium, defining an area of interest on the electronic map, referring to a database to determine whether the database contains at least one restriction value, referring to a remote database to determine whether the remote database contains an additional restriction value, the additional restriction value being distinct from the at least one restriction value, combining restriction values, and determining a total value of the parcel of land based on the combined restriction values.

A map generation device is configured to determine evaluation value of each of a plurality of evaluation items that serve as indices for evaluation the reliability of the positional information of the planimetric feature. The plurality of evaluation items include any of an error amount when arrangement of composing points of the planimetric feature is approximated, a parallelism between an arrangement direction of composing points of the planimetric feature and a movement trajectory of the measuring vehicle, a distance between a position indicated by the position information of the planimetric feature and a position of the measuring vehicle when the position of the planimetric feature is measured, an absolute value of reflection intensity of a position of the planimetric feature obtained from the measurement information or a difference between a position of the planimetric feature and surrounding reflection intensity of the planimetric feature, and so on.

A system for generating information about predicted remaining amount of energy includes processing circuitry that obtains traveling state information which contains current vehicle position information, searches a predicted passage point through which the vehicle is predicted to pass in a future on a basis of the traveling state information when a vehicle traveling route is not set, predicts a predicted remaining amount of energy, the predicted remaining amount of energy being a predicted amount of traveling energy remaining at the time when the vehicle passes the predicted passage point and controls to provide information about the predicted remaining amount of energy and the predicted passage point corresponding to the predicted remaining amount of energy for a user.
