Systems and methods involving obtaining point cloud data from one or more sources corresponding to one or more zones within a real-world space, the point cloud data representing surface features of structures detected within the one or more zones; defining a plurality of first-level nodes based on the point cloud data, individual first-level nodes corresponding to obtained point cloud data corresponding to individual zones of the one or more zones; identifying connections between two or more first-level nodes, the connections between the two or more first-level nodes based on connections between the point cloud data for the zones corresponding to the two or more first-level nodes; and defining a plurality of second-level nodes, individual second-level nodes corresponding to aggregated subsets of first-level nodes for which connections are identified.

Systems and methods for generating, updating and enhancing large-scale high-precision 3D road maps and multi-level road graphs

A method for selecting at least one element of a Graphical User Interface (GUI), displayed on a display of a device using a touch interface of the device. The method includes: detecting on the touch interface a double touch input, the double touch input including a first and second touch inputs on the touch interface, the first and second touch inputs respectively corresponding to a first location and a second location on the GUI; determining a selection location between the first and second locations; upon detecting a release of the first touch input, determining a first selection location corresponding to the selection location at the moment of the release of the first touch input, determining a second selection location on the GUI as defined by a user using the touch interface; and executing a selection of at least one GUI element located between the first and second selection locations.
