Rendering style determination method, rendering method and rendering device for road gland elements

The invention provides a rendering style determination method, rendering method and device for road cover elements. The rendering style determination method for the road cover elements comprises the steps of obtaining first drawing data of a target road in an electronic map and second drawing data of elements located in a preset range of the target road; based on the position information of the first drawing data and the second drawing data, determining a road gland element forming a gland for the first drawing data in the second drawing data and a gland type of the road gland element; determining a blurring rendering style of the road gland element based on the gland type of the road gland element; the blurring rendering style is used for weakening the capping effect of the road capping element on the first drawing data. By rendering the gland elements based on gland type differentiation blurring, the influence of the road gland elements on road display is weakened, and the readability of the electronic map
