A map labeling method that uses all-digital forms to mark the position and orientation of the city as the center

Abstract

The invention discloses a method for marking a map with a city as the center and marking the position and location in full digital form. The steps are as follows: S1: determine the fixed-point position, and identify the code of the fixed-point city where the fixed-point position is located; S2: input in the electronic map The code of the fixed-point city is used to obtain the regional map of the fixed-point city; S3: In the regional map of the fixed-point city, the center of the fixed-point city is determined, and a plane Cartesian coordinate system is established. Determine the coordinates of the fixed-point position in the plane Cartesian coordinate system, and mark the fixed-point position. The invention uses numbers instead of text input, which not only makes input simple, but also facilitates memorization, release and mutual communication. At the same time, digital expressions can be directly calculated without secondary translation into machine codes, so they can be widely used in big data and urban digitization It can also meet the requirements of future digitalization of geographic information.

Description

technical field [0001] The invention relates to the technical field of position labeling, in particular to a map labeling method centering on a city and marking the position and positioning in full digital form. Background technique [0002] An electronic map is a digital map, which is a map that is stored and consulted digitally using computer technology. The method of storing information in electronic maps generally uses vector image storage. The map scale can be enlarged, reduced or rotated without affecting the display effect. In the early days, bitmap storage was used, and the map scale could not be enlarged or reduced. Modern electronic map software generally uses geographic information systems to store and transmit map data, and other information systems. [0003] At present, the map markers entered in the navigation terminal are generally limited to POI (Point of Interest). Use the map browsing mode to move the center of the map to the location of the registration p...
