Question

尝试在ES 6.6.1上创建geo_shape时遇到奇怪的错误。

说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,

    ]

}

我得到了以下错误，这对我来说没有意义，因为我要发送的多边形显然有四个以上的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]",
    "caused_by": {
      "type": "illegal_argument_exception",
      "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的多边形：

如果有人知道此错误的原因，我将不胜感激。

Answer 1

该问题与the shape is self-intersecting（对David Turner表示敬意）有关。其他自相交的形状也存在相同的问题。

GeoJSON规范中没有阻止多边形自相交的东西，但ES并不喜欢。

将该多边形拆分为具有轮廓形状和孔形状的MultiPolygon可解决此问题。

无法创建有效的geo_shape
