The aerial vehicle can receive the first real-time map and the position information from the first computing device, obtain a second real-time map based on second scanning data collected using the second scanning sensor, and obtain a third real-time map based on the first real-time map and the second real-time map.

A tablet-like device is configured to have a slightly negative buoyancy and to hold a sheet of waterproof synthetic paper, or another removable, waterproof recording sheet, onto which notes or messages or sketches can be recorded via a writing implement, in an underwater or marine environment, or another extreme or severe environment.

A method is provided for generating and revising map geometry based on a received image and probe data. A method may include: receiving probe data from a first period of time, where the probe data from a first period of time is from a plurality of probes within a predefined geographic region; generating a first image of the predefined geographic region based on the probe data from the first period of time; receiving probe data from a second period of time different from the first period of time, where the probe data from the second period of time is from a plurality of probes within the predefined geographic region; generating a second image based on the probe data from the second period of time; comparing the first image to the second image; and generating a revised route geometry based on changes detected between the first image and the second image.

An information processing device (100) includes a map information generation unit (11) and a usage amount calculation unit (12). The map information generation unit (11) generates map information by using measurement information including a plurality of types of information measured by a measurement device (300) which measures information on features and is mounted on a measurement vehicle (310). The usage amount calculation unit (12) calculates a usage amount of the map information generation unit (11) used for generating the map information by using at least one of the plurality of types of information included in measurement information.

A flexible light emitting substrate in accordance with an embodiment hereof includes a controller, a base substrate that carries a data source printed or displayed thereon, which defines a plurality of grid locations, and a data display source provided on, under, or within the base substrate and is wirelessly or wiredly coupled to the controller. Each data display source is associated with a respective grid coordinate or with a specific location or with a position of an object or person relative to a boundary displayed on the base substrate. The embodiment further includes a position sensor for determining the current location of a person or object, and a power source for providing power to the data display source and the controller, where the controller is configured for selectively controlling operation of the data display source based at least partially on the determined current location of the person or object.

A mobile body (200) includes a generation unit (264), a first communication unit (220), a second communication unit (230), an acquisition unit (265), a providing unit (266), and an integration unit (267). A generation unit (264) generates map information. The first communication unit (220) communicates with a management device (100). The second communication unit (230) communicates with other mobile body using a communication band different from a communication band used by the first communication unit (220). The acquisition unit (265) acquires first map information generated in other mobile body through communication by the second communication unit (230). The providing unit (266) provides second map information to other mobile body through communication by the second communication unit (230). The integration unit (267) integrates the first map information and the second map information to generate integrated map information.

The present disclosure includes a radar configured to detect surrounding objects and terrain, and a LIDAR configured to detect the surrounding objects and terrain using a narrower detection range and a higher resolution than the radar. The disclosure also includes a first map, such as a wide-area map, generated based on information about the surrounding as detected by the radar, a second map, such as a high-resolution map, based on information about the surroundings as detected by the LIDAR, and a composite map that has the grid width of the first map and the grid width of the second map.

An example of an apparatus is provided. The apparatus includes a light source to emit light. The apparatus further includes a light source controller to control the light source. The light source controller is to change an intensity of the light emitted by the light source. In addition, the apparatus includes a low resolution sensor to measure light data from a reflection of the light off a wall. Also, the apparatus includes a memory storage unit to store the light data and corresponding control data. The apparatus includes an image processing engine to locate and to classify the wall based on the light data and the control data.

Systems, methods, and computing devices for building, operating and using map systems with signature-based map caches are disclosed. Based on the desired map properties included in a formatted map request, a map signature can be generated. The map signature can be used to access a signature based map cache to determine whether a map with identical map properties has been previously generated and stored in cache or otherwise available for retrieval. If the map signature exists in the map cache, the corresponding map can be delivered to a map client. If the map signature does not exist in the map cache, then a map can be generated or rendered based on the map properties in the map request. Once the map is generated, it can be saved to the map cache along with associated map signature for future retrieval.

Various methods, systems, and apparatus for implementing aspects of a digital mapping system are disclosed. One such method includes sending a location request from a client-side computing device to a map tile server, receiving a set of map tiles in response to the location request, assembling said received map tiles into a tile grid, aligning the tile grid relative to a clipping shape, and displaying the result as a map image. Direction control or zoom control objects may be included as interactive overlays on the displayed map image. The displayed map image may also include route or location overlays.
