如何将 geojson 数据添加到 react-map-gl 的 Source 和 Layer Component
How to add geojson data to Source and Layer Component of react-map-gl
我正在使用 react-map-gl
库来处理 mapbox。我想在地图上的某些数据点上创建一条线。地图渲染良好,但地图上未显示线条。
坐标应为 LineString 的二维数组。
dataJS 应该是这样的
const dataJS = {
type: "Feature",
properties: {},
geometry: {
type: "LineString",
coordinates: [
[-67.13734351262877, 45.137451890638886],
[-66.96466, 44.8097],
[-68.03252, 44.3252],
[-69.06, 43.98],
[-70.11617, 43.68405],
