3 results about "Map making" patented technology

The application belongs to the technical field of map knowledge, and particularly relates to a map knowledge representation method based on a knowledge graph. The method first acquires map data, extracts map knowledge therefrom, including concept class knowledge and rule class knowledge, the concept class knowledge being common sense knowledge in the field of cartography and including map element knowledge; the rule class knowledge being various models, rules and principles formed in the process of map making; then generates a map knowledge network graph based on the knowledge graph according to the map element knowledge; and finally performs knowledge reasoning according to the rule class knowledge, completes the map knowledge network graph, and generates new entities and / or new entity relationships. The application fully mines geographical knowledge contained in a map, provides a basis for all-round knowledge mining and fusion of the map, and has certain reference value for realizing the transformation of 'data-information-knowledge'.

A game map generation method and apparatus, and a program product and an electronic device. The game map generation method comprises: displaying a game editing scene in a graphical user interface, wherein the game editing scene comprises a scene component (S110); in response to an attribute editing operation for a map component, editing an attribute parameter of the map component, wherein the attribute parameter comprises a scene valid area corresponding to the map component, and the scene valid area is an area in the game editing scene (S120); performing image acquisition of the scene valid area by means of a map camera, so as to obtain a scene image of the scene valid area (S130); and displaying the scene image by means of the map component (S140). An editable map component is provided, such that the convenience of making a map is improved, and the personalized customization of maps can also be realized for different game scenes. The present invention has strong applicability and can meet different creation requirements of users.

This application discloses a method, apparatus, device, medium, and program product for drawing map data, relating to the field of computer technology. The method includes: receiving a selection operation for a first point cloud location in a point cloud data space; obtaining marker parameters corresponding to ground markers based on the first point cloud location; constructing a bounding box corresponding to the marker parameters; traversing the bounding box's range to determine the distribution range of the point cloud data of the ground markers on the ground in the point cloud data space, generating a drawing area corresponding to the distribution range; and generating map drawing data of the ground markers based on the drawing area. In this application, the operator only needs to select a specific point cloud location to obtain the map drawing data of the ground markers, simplifying the drawing operation steps and improving map drawing efficiency. This application can be applied to scenarios such as large-scale transportation, map production, 3D modeling, and architectural design.
