A system for location-based analytics may include a location map data store containing electronic records that are associated with a plurality of configurable map tile polygons defining a location map. Each record may include, for example, a unique map til...

Certain aspects of the present disclosure provide a method for generating a map. A method generally includes obtaining sensor data corresponding to one or more sensors. The method includes inputting the sensor data to a map generation model. The method obt...

Systems and methods for generating three-dimensional meshes that represent road surfaces of a road network are disclosed herein. In one example, a system includes a processor and a memory having instructions that, when executed by the processor, cause the ...

In various examples, updating pose graphs using versioned data for autonomous and/or semi-autonomous systems and applications is described herein. Systems and methods herein may generate and/or update a pose graph (e.g., a pose map) associated with an envi...

An embodiment may include, for a real world moving object moving along a real world path, modeling trajectory of the moving object along a polygon. The polygon may have a plurality of line segments and vertices and may represent the real world path for the...

A method for representing linear features in a location content management system is disclosed. A linear feature is represented using a sequence of routing points that define a unique path when routed on a map through those points. A routing point consists...

A navigation device has a database which stores index data for respectively a tile (25) of a tiling. The index data includes for each one of plural cells of a grid which is superimposed on the tile respectively an identifier for each triangular face (26-39...

The method involves activating a navigation functional unit, and reading card data i.e. extending elements, of a map data storage unit (4). A check is made whether extension data are stored in an extension database (5), where the database includes attribut...

A problem to be solved by the present invention is to make it possible to compress shape information with high efficiency even with such data represent a shape of a short segment of road or the like, and further reduce the data amount. The starting-end loc...
