Provided are a computer system and methods related to a map display. A method includes but is not limited to receiving a request for the map, the map illustrating one or more locations; determining a status associated with at least one of the one or more locations on the map, the status being a function of one or more location interaction rules associated with the at least one of the one or more locations on the map; and generating a signal related to indicating on the map the status associated with the at least one of the one or more locations.

A visual teaching aid (100) assists teaching a cleaning order for a predefined area (106). The visual teaching aid can include a legend portion (103) defining a plurality of portions (105) of the predefined area, while a predefined area portion (104) pictorially illustrates the plurality of portions. The legend portion can define a plurality of sequential numerical indicia (107) indicating a predefined order in which the plurality of portions should be cleaned. The predefined area portion can include a plurality of visual indicators (110) assigned to the plurality of portions on a one-to-one basis. The visual teaching aid can be included with one or more cleaning cloths (400,600) or microfiber booklets (801,808) in a cleaning package assembly (1300).

Techniques in this disclosure may provide a user interface that concurrently displays multiple panels which provide visualization of emergency call data of a law enforcement agency. The user interface can provide a high-level overview of emergency calls in a geographical area. Each panel in the user interface can provide visualization of the emergency calls and/or statistics relating to the calls. A user can customize which panels to include in the user interface and/or customize setting for each panel. The user may apply various types of filters to the data displayed in the user interface, and the panels can update the visualizations according to the filters. The user interface can also provide the ability to show data at various levels of detail within the same user interface or panel. The techniques in the disclosure can provide a convenient, digestible overview of tactical and/or strategic data in a single user interface.

A projection (projected image) is drawn by perspective projection of a three-dimensional model with a background image having improved reality. When a sightline of the perspective projection looks down from above, the projected image is drawn into an object drawing area which is a lower part of an image picture. A background layer representing the stratosphere is separately generated by two-dimensionally drawing a background image, in which the stratosphere (hatched area) is opaque, while the remaining area is transparent. The boundary between the opaque portion and the transparent portion forms a curved line that is convex upward to express a curved horizon. The background layer is superimposed in front of the projected image, not behind the projected image, thereby covering an upper edge portion of the projected image including a straight-lined upper edge, so as to provide a curved boundary realizing a curved pseudo horizon in the image picture.

Drive assist systems, methods, and programs display, on a display, an image in which a destination location icon that indicates a destination location is superimposed on a scene in front of a mobile body. The systems, methods, and programs acquire a length of a frontage of the destination location along a road on which the mobile body is present and specify a display position of the destination location icon on the basis of an estimated position of the mobile body such that the display position of the destination location icon is a position within the frontage. The systems, methods, and programs display on the display, an image in which the destination location icon is superimposed on the display position of the destination location icon in the scene in front of the mobile body.

Provided are a first DSM generating unit, a ground DEM storing unit, a first DEM generating unit, a 2 m ground DEM storing unit, a first DHM generating unit, a first inclination image generating unit, a first inclination image storing unit, a first red relief image generating unit, a first gradient-tinted image generating unit, a first feature height-based colored image generating unit, a first building height comparison image generating unit, and the like. Accordingly, an image does not look dirty, and an image in which a shape of a feature is outlined clearly is obtained.

A navigation method and system, a map data management cloud and data update method thereof, wherein the navigation method includes: a map data management cloud receiving a navigation request from a mobile terminal, wherein the navigation request includes: requesting for route information of the navigation; the map data management cloud obtaining an optimal route according to the navigation request and collected real-time route condition information; wherein the real-time route condition information includes: route condition information, uploaded by at least one mobile terminal, collected during navigation processes of the at least one mobile terminal; the map data management cloud sending the optimal route to the mobile terminal which sends the navigation request, thereby providing real-time navigation data and improving navigation efficiency.

An electronic route navigation method is used in navigating an autonomous vehicle in a road network. In an implementation of the method a map is stored on at least one computer, and is sectioned into quads by a processor. The smallest size quads are grouped as base level quads. Extended area quads are defined to contain the area of a plurality of base level quads. Thereafter, a route along a road is calculated from a start point to a destination point. Further extended area quads on the map that do not contain the start point or the destination point are used for cross routing. In said cross routing only the road routes crossing the extended area quad leading from the start point to destination point are calculated.
