申请天地图开发权限
- 注册天地图
- 控制台创建应用,应用类型选浏览器端,因为我们是浏览器使用
- 创建完成后进入资源服务选择使用的地图,此处我使用经纬度矢量地图
- 点击进去可以看到地图服务的URL 后面要用
ArcGis 接入天地图
- ArcGis 4x版本中使用三方地图服务是使用WebTileLayer这个图层
- 注意坐标系:天地图提供经纬度坐标系与墨卡托两种,此处我使用的是经纬度坐标系,但是因为ArcGis 默认是墨卡托所以使用时要将spatialReference的wkid设置为4326
- 经纬度和墨卡托调用URl中的一些参数是不一样的,代码中有注明
import WebTileLayer from '@arcgis/core/layers/WebTileLayer'
import TileInfo from '@arcgis/core/layers/support/TileInfo'// 瓦片调用配置,直接复制使用
