Abstract

The invention discloses a map rendering method and device, a storage medium and an electronic device. Wherein, the method includes: acquiring a rendering instruction, the rendering instruction is used to at least instruct to render the inflection point between the first road segment and the second road segment in the map; in response to the rendering instruction, find the first coordinate point and the second coordinate point in the map point, the first side where the first vertex is located on the first area and the second side where the second vertex is located on the second area intersect at the first coordinate point, the extension line of the third side where the first vertex is located on the first area and The extension line of the fourth side where the second vertex is located on the second area intersects at the second coordinate point; according to the first coordinate point, the second coordinate point, the first vertex and the second vertex, a rendering for connecting the first vertex and The arc of the second vertex. The invention solves the technical problem of inaccurate borders of road inflection point areas rendered on the map in the related art.

Description

technical field [0001] The present invention relates to the field of electronic maps, and in particular, to a map rendering method and device, a storage medium, and an electronic device. Background technique [0002] The symbolization method of geospatial entities is an important research content in the field of geographic information and cartography. Compared with the commonly used point symbols and polygon symbols, line symbols are often more difficult and time-consuming because they need to be filled and drawn along the direction of linear features. In addition to the usual solid and dashed lines, the line symbols required in map representations are more complex. For example, the line symbol of the main road of the city is a double-line primitive with a frame; the railway symbol is a black and white primitive with a frame; the unilateral boundary line symbol is a toothed primitive. These line symbols use different geometric shapes to form a primitive with semantic infor...
