Mapbox Gl JS-绘制汽车标记 [英] Mapbox gl js - draw a car marker

问题描述

我需要根据其位置绘制汽车标记.但是，与所有官方示例(例如此)不同，我希望标记的大小取决于缩放级别.而且，我希望它也具有方向性-我需要根据汽车的方向旋转它. Mapbox GL JS是否有可能，以及如何做到?

I need to draw a car marker based on it's position. But, unlike all official examples, like this, I want size of my marker to be dependent on zoom level. And, I want it to have heading as well - I need to rotate it based on the car's heading. Is it possible with Mapbox GL JS, and how to do it?

推荐答案

符号图层 https://www.mapbox.com/mapbox-gl-js/style-spec#layers-symbol 最适合此操作，请参见以下示例 https://www.mapbox.com/mapbox-gl-js/example/rotating-controllable -marker/

The Symbol layer https://www.mapbox.com/mapbox-gl-js/style-spec#layers-symbol is best suited for this, see this example https://www.mapbox.com/mapbox-gl-js/example/rotating-controllable-marker/
