如果只是利用mapbox加载tif，那就初始化一个空白球就可以了，可以结合mapbox-gl-draw工具对tif进行标注，当然tif要发布成服务才行。

import { Component, ElementRef, ViewChild } from '@angular/core';

    const map = new mapboxgl.Map({
      container: this.mapContainer.nativeElement,
      projection: 'globe', // 设置为球体投影

        ],

        },
      });
    });
    map.flyTo({

      zoom: 12,
    });
    const draw = new MapboxDraw({
