假设我有 45.6987 和 34.34433 这样的点 现在该点显示为圆圈，我想将该点显示为正方形或方框。
最佳答案
以下是对https://www.mapbox.com/mapbox-gl-js/example/custom-marker-icons/的轻微修改使用自定义 CSS 的地方。
图像被注释掉并使用带颜色的 DIVS。请注意，给定 GEOJSON 的属性包括“图标大小”——这用于“正方形”的宽度和长度。
总而言之，此示例使用 document.createElement 创建您需要的自定义标记。如果图层中有更多内在选项(如正方形等)而不是仅仅用圆圈来指示 map 上的点，那就太好了。
-确保添加您的 token 以使代码正常工作。
