一、EXAMPLE

{
  "type": "FeatureCollection",
  "features": [
    {
      "type": "Feature",
      "geometry": { "type": "Point", "coordinates": [102.0, 0.5] },
      "properties": { "prop0": "value0" }
    },
    {
      "type": "Feature",
      "geometry": {
        "type": "LineString",
        "coordinates": [
          [102.0, 0.0],
          [103.0, 1.0],
          [104.0, 0.0],
          [105.0, 1.0]
        ]
      },
      "properties": {
        "prop0": "value0",
        "prop1": 0.0
      }
    },
    {
      "type": "Feature",
      "geometry": {
        "type": "Polygon",
        "coordinates": [
          [
            [100.0, 0.0],
            [101.0, 0.0],
            [101.0, 1.0],
            [100.0, 1.0],
            [100.0, 0.0]
          ]
        ]
      },
      "properties": {
        "prop0": "value0",
        "prop1": { "this": "that" }
      }
    }
  ]
}

二、名词解释

1. *type

• 该项必填
• 可选值有
  • Point
    点(=1)
  • MultiPoint
    多点(>=2)
  • LineString
    线（>=2）
  • MultiLineString
    多线
  • Polygon
    几何
  • MultiPolygon
    多几何
  • GeometryCollection
    图形组合
  • Feature
  • FeatureCollection

2. 当type为Feature时

• geometry 必填
• properties 必填
• id 非必填

3. 当type为FeatureCollection时

• features 必填

4. coordinates

必填，数组，从属于 geometry 属性。
