Elasticsearch Essentials

Geo-shapes

Geo-shapes are completely different from geo-points. Until now we have worked with simple geo-location and rectangle searches. However, with geo-shapes, the sky is the limit. On a map, you can simply draw a line, polygon, or circle and ask Elasticsearch to populate the data according to the co-ordinates of your queries, as seen in the following image:

Let's see some of the most important geo-shapes.

Point

A point is a single geographical coordinate, such as your current location shown by your smart-phone. A point in Elasticsearch is represented as follows:

{
    "location" : {
        "type" : "point",
        "coordinates" : [28.498564, 77.0812823]
    }
}
