问题描述
尝试在ES 6.6.1上创建geo_shape时遇到奇怪的错误.
I'm getting a weird error while trying to create a geo_shape on ES 6.6.1.
说我的索引具有以下映射:
Say my index has the following mapping:
PUT index
{
"mappings" : {
"doc" : {
"properties" : {
"parcel" : {
"type" : "geo_shape"
}
}
}
}
}
然后我尝试索引以下形状:
Then I try to index the following shape:
PUT index/doc/1
{
"parcel": {
"type": "Polygon",
"coordinates": [

我收到以下错误，这对我来说没有意义，因为我要发送的多边形明显有4个以上的多边形点并且已关闭.
And I'm getting the following error, which doesn't make sense to me since the polygon I'm sending clearly has more than 4 polygon points and is closed.
{
"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:
Drawing the same polygon on http://geojson.io yields the following valid polygon:
如果有人知道此错误的原因，我将不胜感激.
I'd appreciate if someone has an idea of what could be the reason of this error.
推荐答案
The problem was related to the fact that the shape is self-intersecting (kudos goes to David Turner). Other self-intersecting shapes also exhibit the same issue.
GeoJSON规范中没有阻止多边形自相交的东西，但ES却不喜欢.
There's nothing in the GeoJSON spec preventing polygons from self-intersecting, yet ES doesn't like it.
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.
Splitting that Polygon into a MultiPolygon with an outline shape and a hole shape fixes the issue.
