Polygon

open class Polygon : Geometry<ArrayList<LngLatAlt>>

Coordinates of a Polygon are an array of linear ring coordinate arrays. The first element in the array represents the exterior ring. Any subsequent elements represent interior rings (or holes).

No holes:

  {
      "type": "Polygon",
      "coordinates": [
          [
              [100.0, 0.0],
              [101.0, 0.0],
              [101.0, 1.0],
              [100.0, 1.0],
              [100.0, 0.0]
          ]
      ]
  }

With holes:

  {
      "type": "Polygon",
      "coordinates": [
          [
              [100.0, 0.0],
              [101.0, 0.0],
              [101.0, 1.0],
              [100.0, 1.0],
              [100.0, 0.0]
          ],
          [
              [100.8, 0.8],
              [100.8, 0.2],
              [100.2, 0.2],
              [100.2, 0.8],
              [100.8, 0.8]
          ]
      ]
  }
