The invention discloses a Canvas-based
radar map generation method and device, a storage medium and a terminal, and the method comprises the steps of drawing a Canvas map layer on a canvas, obtaininga corresponding drawing result, and outputting the drawing result, the Canvas map layer comprising a first Canvas map layer for drawing a
radar map and / or a second Canvas map layer for drawing a coordinate
system; and displaying the drawing result on a display screen of the
display device. According to the
radar map generation method provided by the embodiment of the invention, the canvas with theCanvas elements is introduced, and the radar map and the coordinate
system can be drawn on the Canvas layer of the canvas, so that due to the introduction of the Canvas for drawing, rendering can bedirectly carried out on a front-end browser, and the rendering speed is increased by at least one time compared with that of other rendering methods at present; besides, due to the fact that the canvas with the Canvas elements is introduced, in the drawing process, the canvas can adapt to the display screen of the
display device, data does not need to be requested again, and therefore the drawingprocess is simplified.
