javascript - 加入两个边界框 bboxes

Question

我有两个边界框，想创建一个包含这 2 个的大边界框 - 加入它们。

例如（turf.bbox 的 2 个结果）：

  var bboxCircles = turf.bbox({
            "type": "FeatureCollection",
            "name": "bboxes",
            "features": circles
          });

          var bboxPoly = turf.bbox({
            "type": "FeatureCollection",
            "name": "bboxes",
            "features": polygon
          });

        bboxCircles = [10, 5, 15, 12];
        bboxPoly = [-35.9999999999999, -18.9999999999999, 35.4250000000001, 45.5000000000001];

var resBbox = bboxCircles.concat(bboxPoly).reduce(function(result, value, index, array) {
        if (index % 2 === 0)
          result.push(array.slice(index, index + 2));
        return result;
      }, []);

      var bounds = new mapboxgl.LngLatBounds();
      resBbox.forEach(item => {
          bounds.extend(item);
      });
      map.fitBounds(bounds);

草坪等有简单的方法吗？谢谢

也许这可以使用bboxPolygon,combine和的组合来解决bbox。bboxPolygon将边界框转换为多边形特征。

var resBbox = turf.bbox(turf.bboxPolygon(bboxCircles).combine(turf.bboxPolygon(bboxPoly)));
