Map labeling method for labeling positions and positioning in all-digital form by taking city as center

Abstract

The invention discloses a map labeling method for labeling positions and positioning in an all-digital form by taking cities as centers, which comprises the following steps: S1, determining fixed-point positions, and identifying codes of fixed-point cities where the fixed-point positions are located; S2, inputting a code of a fixed-point city into the electronic map, and obtaining a regional map of the fixed-point city; and S3, determining the center of the fixed-point city in the regional map of the fixed-point city, establishing a plane rectangular coordinate system, determining the coordinates of the fixed-point position in the plane rectangular coordinate system according to the position relationship between the center of the fixed-point city and the fixed-point position, and marking the fixed-point position. According to the method, text input is replaced with numbers, input is easy, memorization, release and mutual communication are facilitated, meanwhile, numerical calculation can be directly conducted through number expression, secondary translation into machine codes is not needed, and therefore the method can be widely applied to big data and urban digital services, and the requirement for future geographic information digitization can be met.

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...
