計算沿線的點

var line = turf.lineString([
        [109.502991, 29.68718],
        [108.837829, 32.969237],
        [113.567871, 37.200787]
      ]);
var options = {units: 'miles'};

var along = turf.along(line, 300, options);

計算區(qū)域面積

var polygon = turf.polygon([[
        [108.09876, 37.200787],
        [106.398901, 33.648651],
        [114.972103, 33.340483],
        [113.715685, 37.845557],
        [108.09876, 37.200787]
      ]]);

var area = turf.area(polygon);

計算邊界框

var line = turf.lineString([
        [104.99467, 30.071677],
        [107.13797, 36.550462],
        [112.607082, 34.991467]
      ]);
var bbox = turf.bbox(line);
var bboxPolygon = turf.bboxPolygon(bbox);

計算多邊形

var bbox = [105.361046, 35.356724, 111.59974, 30.934089];

var poly = turf.bboxPolygon(bbox);
