Electronic map lettering line folding method and device

Abstract

The invention provides an electronic map lettering line folding method and device, and relates to the field of electronic map lettering. The method includes the steps that length information of target lettering is acquired; according to the length information of the target lettering, whether the length of the target lettering is larger than a first threshold or not is judged; if the length of the target lettering is larger than the first threshold, word segmentation is conducted on the target lettering, and then a word segmentation result is acquired; according to the word segmentation result, automatic line folding is conducted on the target lettering. By the adoption of the method and device, automatic line folding can be conducted on the electronic map lettering quickly, efficiently, reasonably and attractively.

Description

technical field [0001] The invention relates to the field of electronic map notation, and in particular provides a method and device for noting a branch on an electronic map. Background technique [0002] Annotation is a text label that expresses the name of geographical things or the number of mountain height and water depth on the map, etc., and plays an explanatory role. [0003] Because some annotations contain too much text, it may not be reasonable to display them on the map (for example, the display is not beautiful, the text cannot be displayed in full, etc.), which requires reasonable branching of annotations. At present, branch work is mainly carried out manually, and this traditional method cannot meet the growing demand for electronic map services. In addition, there are some software that automatically divides annotations. By dividing the annotations according to the length of the annotations, and then displaying them on the map, this method of dividing annotat...

[0003] Because some annotations contain too much text, it may not be reasonable to display them on the map (for example, the display is not beautiful, the text cannot be displayed in full, etc.), which requires reasonable branching of the annotations

At this stage, branch work is mainly done manually. This traditional method cannot meet the growing demand for electronic map services.

In addition, there are some software that automatically divides annotations. By dividing the annotations according to the length of the annotations, and then displaying them on the map, this method of dividing annotations based only on the number of words is unreasonable, and the whole phrase or belonging to the The text of the same content is hard-divided into two lines, resulting in disorganized display
