我有两个边界框,想要创建一个包含这个2的大框 - 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? 感谢
答案 0 :(得分:1)
也许可以使用bboxPolygon
,combine
和bbox
的组合来解决这个问题。 bboxPolygon
将边界框转换为多边形要素。
var resBbox = turf.bbox(turf.bboxPolygon(bboxCircles).combine(turf.bboxPolygon(bboxPoly)));
