Geobounds aggregations
The geo_bounds metric is a multi-value metric aggregation that calculates the geographic bounding box containing all values of a given geo_point or geo_shape field. The bounding box is returned as the upper-left and lower-right vertices of the rectangle in terms of latitude and longitude.
The following example returns the geo_bounds metrics for the geoip.location field:
GET opensearch_dashboards_sample_data_ecommerce/_search
{
"size": 0,
"aggs": {
"geo": {
"geo_bounds": {
"field": "geoip.location"
}
}
}
}

Aggregating geoshapes
To run an aggregation on a geoshape field, first create an index and map the location field as a geo_shape:
PUT national_parks
{
"mappings": {
"properties": {
"location": {
"type": "geo_shape"
}
}
}
}
Next, index some documents into the national_parks index:
PUT national_parks/_doc/1
{
"name": "Yellowstone National Park",
"location":
{"type": "envelope","coordinates": [ [-111.15, 45.12], [-109.83, 44.12] ]}
}
PUT national_parks/_doc/2
{
"name": "Yosemite National Park",
"location":
{"type": "envelope","coordinates": [ [-120.23, 38.16], [-119.05, 37.45] ]}
}
PUT national_parks/_doc/3
{
"name": "Death Valley National Park",
"location":
{"type": "envelope","coordinates": [ [-117.34, 37.01], [-116.38, 36.25] ]}
}
You can run a geo_bounds aggregation on the location field as follows:
GET national_parks/_search
{
"aggregations": {
"grouped": {
"geo_bounds": {
"field": "location",
"wrap_longitude": true
}
}
}
}
The optional wrap_longitude parameter specifies whether the bounding box returned by the aggregation can overlap the international date line (180° meridian). If wrap_longitude is set to true, the bounding box can overlap the international date line and return a bounds object in which the lower-left longitude is greater than the upper-right longitude. The default value for wrap_longitude is true.
The response contains the geo-bounding box that encloses all shapes in the location field:

Currently, OpenSearch supports geoshape aggregation through the API but not in OpenSearch Dashboards visualizations. If you’d like to see geoshape aggregation implemented for visualizations, upvote the related GitHub issue.
