This page shows how to create an index with geospatial data and retrieve vector tile results using the vector tile search API.
You can learn how to:
The following requests create the museum
index and add several geospatial location
values.
PUT museums
{ "mappings": { "properties": { "location": { "type": "geo_point" }, "name": { "type": "keyword" }, "price": { "type": "long" }, "included": { "type": "boolean" } } } } POST museums/_bulk?refresh { "index": { "_id": "1" } } { "location": "POINT (4.912350 52.374081)", "name": "NEMO Science Museum", "price": 1750, "included": true } { "index": { "_id": "2" } } { "location": "POINT (4.901618 52.369219)", "name": "Museum Het Rembrandthuis", "price": 1500, "included": false } { "index": { "_id": "3" } } { "location": "POINT (4.914722 52.371667)", "name": "Nederlands Scheepvaartmuseum", "price":1650, "included": true } { "index": { "_id": "4" } } { "location": "POINT (4.914722 52.371667)", "name": "Amsterdam Centre for Architecture", "price":0, "included": true }
The following request searches the index for location
values that intersect the 13/4207/2692
vector tile.
GET museums/_mvt/location/13/4207/2692
{ "grid_agg": "geotile", "grid_precision": 2, "fields": [ "name", "price" ], "query": { "term": { "included": true } }, "aggs": { "min_price": { "min": { "field": "price" } }, "max_price": { "max": { "field": "price" } }, "avg_price": { "avg": { "field": "price" } } } }
The API returns results as a binary vector tile. When decoded into JSON, the tile contains the following data:

Elasticsearch may translate a vector tile search API request with a grid_agg
argument of geotile
and an exact_bounds
argument of true
into the following search:
GET my-index/_search
{ "size": 10000, "query": { "geo_bounding_box": { "my-geo-field": { "top_left": { "lat": -40.979898069620134, "lon": -45 }, "bottom_right": { "lat": -66.51326044311186, "lon": 0 } } } }, "aggregations": { "grid": { "geotile_grid": { "field": "my-geo-field", "precision": 11, "size": 65536, "bounds": { "top_left": { "lat": -40.979898069620134, "lon": -45 }, "bottom_right": { "lat": -66.51326044311186, "lon": 0 } } } }, "bounds": { "geo_bounds": { "field": "my-geo-field", "wrap_longitude": false } } } }
