function del_dottedpoint(name: string, map: any) {
  let arr = [];
  let tyid = name; //台风id
  let geo = map.getSource("point" + tyid)._data;
  let _data = geo.features;
  for (let i = 0; i < _data.length; i++) {
    if (_data[i].properties.type != "2") {
      arr.push(_data[i]);
    }
  }
  geo.features = arr;
  map.getSource("point" + name).setData(geo);
