Geo Bounds Aggregation

Geo Bounds Aggregation

edit

This functionality is in technical preview and may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.

A metric aggregation that computes the bounding box containing all geo_point values for a field.

Example:

{
    "query" : {
        "match" : { "business_type" : "shop" }
    },
    "aggs" : {
        "viewport" : {
            "geo_bounds" : {
                "field" : "location", 
                "wrap_longitude" : true 
            }
        }
    }
}

The geo_bounds aggregation specifies the field to use to obtain the bounds

wrap_longitude is an optional parameter which specifies whether the bounding box should be allowed to overlap the international date line. The default value is true

The above aggregation demonstrates how one would compute the bounding box of the location field for all documents with a business type of shop

The response for the above aggregation:

{
    ...

    "aggregations": {
        "viewport": {
            "bounds": {
                "top_left": {
                    "lat": 80.45,
                    "lon": -160.22
                },
                "bottom_right": {
                    "lat": 40.65,
                    "lon": 42.57
                }
            }
        }
    }
}
