How to construct geo\_point field in logstash from Kafka input? This is my logstash config file. But Kibana not recognizing as a geo\_point field.

input {

```
kafka {
        bootstrap_servers => "localhost:9095"
        topics => ["ma_readings", "sms_log"]
		decorate_events => true
}

```

}

filter {

```
json {
	source => "message"
	remove_field => ["message"]
}

if [@metadata][kafka][topic] == "ma_readings" {
	mutate{
		add_field => { "Location" => ["%{Lat}","%{Lon}"] }        		
		remove_field => ["Lat", "Lon"]
	}
	mutate {
	  convert => { "Location" => "float" }
	}
}

```

}

output {

```
elasticsearch {
	hosts => ["https://localhost:9200"]
	index => "%{[@metadata][kafka][topic]}"
	workers => 1
	user => 'logstash_internal2'
	password => 'logstash_internal2'
	ssl_certificate_verification => false

```

}

Welcome,

Just a check, but did you assign it the geopoint type in your mapping?  
see: [Geopoint field type | Elasticsearch Guide [8.7] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/geo-point.html)

```auto
PUT <index-name>
{
  "mappings": {
    "properties": {
      "Location": {
        "type": "geo_point"
      }
    }
  }
}

```

And according to the documentation, if you provide the geopoint as an array, the order is **lon** , **lat**. So you need to change the order in your filter.  
And maybe you need to do the conversion to float before you create the array, but I am not sure.
