未能创建有效 geo_shape

Question

我在 ES 6.6.1 上尝试创建 geo_shape 时遇到奇怪的错误。

假设我的索引具有以下映射：

PUT index
{
    "mappings" : {
      "doc" : {
        "properties" : {
          "parcel" : {
            "type" : "geo_shape"
          }
        }
      }
    }
}

然后我尝试索引以下形状：

PUT index/doc/1
{
  "parcel": {
    "type": "Polygon",
    "coordinates": [
      [
        [
          -116.96938484446626,

    ]
  }
}

我收到以下错误，这对我来说没有意义，因为我发送的多边形显然有超过 4 个多边形点并且已关闭。

{
  "error": {
    "root_cause": [
      {
        "type": "mapper_parsing_exception",
        "reason": "failed to parse field [parcel] of type [geo_shape]"
      }
    ],
    "type": "mapper_parsing_exception",
    "reason": "failed to parse field [parcel] of type [geo_shape]",

      "reason": "at least 4 polygon points required"
    }
  },
  "status": 400
}

在 http://geojson.io 上绘制相同的多边形会产生以下有效多边形：

如果有人知道此错误的可能原因，我将不胜感激。

Answer 1

问题与 the shape is self-intersecting 这一事实有关（David Turner 的荣誉）。其他自相交形状也存在同样的问题。

GeoJSON 规范中没有任何内容可以防止多边形自相交，但 ES 不喜欢它。

将该多边形拆分为具有轮廓形状和孔形状的多边形可以解决此问题。
