我需要使用PHP計算多段線周圍的多段線。PHP計算多段線周圍的多邊形
所以輸入看起來像
[42.8476193, -78.8186415]
[42.8476193, -78.8186415]
[42.8476974, -78.8183599]
[42.847746, -78.818281]
[42.84806, -78.81784]
[42.848293, -78.817524]
[42.848507, -78.817246]
[42.848708337614, -78.816972090002]
[42.848710725944, -78.816968742025]
輸出將被給予寬的多邊形線。在MAP圖所示。這應該計算基於折線(藍色)綠色多邊形的線
簾線
謝謝
