I'm trying to insert a location that is using a circle processor to generate the circle points. Location [30, 10] in the document is generated with the circle points properly.  
docs: [Circle processor | Elasticsearch Guide [8.5] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/8.5/ingest-circle-processor.html)

```auto
PUT _ingest/pipeline/polygonize_circles
{
  "description": "translate circle to polygon",
  "processors": [
    {
      "circle": {
        "field": "circle",
        "error_distance": 1,
        "shape_type": "geo_shape"
      }
    }
  ]
}

PUT circles
{
  "mappings": {
    "properties": {
      "circle": {
        "type": "geo_shape"
      }
    }
  }
}
 

PUT circles/_doc/2?pipeline=polygonize_circles
{
  "circle": {
    "type": "circle",
    "radius": "40m",
    "coordinates": [35.539917, -78.472000]
  }
}

GET circles/_doc/2

But if I use another location. The generated coordinate looks like an oval with the wrong radius.

my location [35.54171753710938, -78.472]

created coordinates:

            "type": "Polygon"
          }

```

Is it an issue or It's working as expected? Because the coordinates are not a circle so it's impacting the search result.

This is working as expected, the circle processor "polygonize" the circle as the index does not support indexing circles natively.

@Ignacio_Vera

Thanks for your reply. Is there any way to transform a point along with the radius to a circle similar CircleShape in ESS 6.8? We are doing the upgrade from 6.8 to 8.5.3 and got this issue by using the Circle Processor.  
When I map the generated coordinate in Gooogle Maps. It looks like this.

I tried your first example and indeed the generated polygon looks in kibana maps like :

But this is a problem of the precision you are using. If I change the precision to 0.001:

```auto
PUT _ingest/pipeline/polygonize_circles
{
  "description": "translate circle to polygon",
  "processors": [
    {
      "circle": {
        "field": "circle",
        "error_distance": 0.01,
        "shape_type": "geo_shape"
      }
    }
  ]
}

```

Then it looks much better:

Could you explain how are you generating the second example? I tried to see if I can reproduce it but I could not. I tried the following:

```auto
PUT _ingest/pipeline/polygonize_circles
{
  "description": "translate circle to polygon",
  "processors": [
    {
      "circle": {
        "field": "circle",
        "error_distance": 100,
        "shape_type": "geo_shape"
      }
    }
  ]
}

PUT circles/_doc/2?pipeline=polygonize_circles
{
  "circle": {
    "type": "circle",
    "radius": "2000m",
    "coordinates": [-122.25, 37.47]
  }
}

```

And it looks like:

Sorry. I missed it. The input coordinate should be lon, lat instead of lat, lon. It's working now.
