将传单 geojsonFeature 对象的坐标数组从十进制值转换为整数值

Question

我需要 convert/display 多个对象中的传单坐标从十进制到整数值，以便在 turfjs 方法中使用它：

https://www.npmjs.com/package/@turf/boolean-point-in-polygon

coord = geojsonFeature.geometry.coordinates:

{type: "D", designator: "EPD53A", availabilities: Array(1), info: Array(2), geometry: {…}}
{type: "TRA", designator: "EPTR105", availabilities: Array(1), info: Array(2), geometry: {…}}
{type: "D", designator: "UMD192", availabilities: Array(1), info: Array(2), geometry: {…}}
(...)

geometry:
  type: "Polygon"
    coordinates: Array(1)
      0: Array(8):
        0: (2) [16.845, 54.587777778]
        1: (2) [16.647777778, 54.515]
        2: (2) [16.545277778, 54.543611111]
        (...)

有什么简单的方法吗？ (angular/typescript)

我正在尝试检查点击点是否位于两个或多个图层多边形上。我真的需要将此值转换为整数吗？

    var pt2 = turf.point([22.65380859375, 49.710272582105695]);
    var multiPoly = turf.multiPolygon([[[
        [22.828611111111112, 49.68472222222222],
        [23.065833333333334, 49.9],
        [23.20861111111111, 49.843333333333334],
        [22.98611111111111, 49.650555555555556],
        [22.828611111111112, 49.68472222222222],
        [22.828611111111112, 49.68472222222222],
        [22.828611111111112, 49.68472222222222]
    ]]]);
    console.log("test-turf",turf.booleanPointInPolygon(pt2, multiPoly));

它returns假

Answer 1

所有 TurfJS 方法都接受（格式良好的）GeoJSON 作为输入。坐标不需要使用整数值。

It returns false

你对 boolanPointInPolygon returns 的调用是错误的，因为那个点在那个多边形之外：
