Geo-point and geo-shape types in Elasticsearch - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a geo-point field in the mapping.

Elasticsearch

{
  "mappings": {
    "properties": {
      "location": {
        "type": "[1]"
      }
    }
  }
}

Ckeyword

Dgeo_point

💡 Hint

Common Mistakes

Using 'geo_shape' instead of 'geo_point' for simple coordinates.

Using 'text' or 'keyword' which are not geo types.

The geo_point type is used to store latitude and longitude coordinates for geo-location queries.

2fill in blank

medium

Complete the code to define a geo-shape field in the mapping.

Elasticsearch

{
  "mappings": {
    "properties": {
      "area": {
        "type": "[1]"
      }
    }
  }
}

Drag options to blanks, or click blank then click option'

Ageo_point

Bgeo_shape

Cinteger

Ddate

💡 Hint

Common Mistakes

Using 'geo_point' when a shape is needed.

Using non-geo types like 'integer' or 'date'.

The geo_shape type is used to store complex shapes like polygons, lines, and circles.

3fill in blank

hard

Fix the error in the geo-point document by completing the coordinates array correctly.

Elasticsearch

{
  "location": {
    "type": "point",
    "coordinates": [[1]]
  }
}

Drag options to blanks, or click blank then click option'

A"lat", "lon"

B"40.12", "-71.34"

C[-71.34, 40.12]

D40.12, -71.34

💡 Hint

Common Mistakes

Reversing latitude and longitude order.

Using strings instead of numbers.

Including keys inside the coordinates array.

Geo-point coordinates must be an array with longitude first, then latitude, as numbers.

4fill in blank

hard

Fill both blanks to create a geo-shape polygon with the correct type and coordinates.

Elasticsearch

{
  "area": {
    "type": "[1]",
    "coordinates": [2]
  }
}

Drag options to blanks, or click blank then click option'

Apolygon

B[[[-70, 40], [-80, 30], [-90, 40], [-70, 40]]]

C[[-70, 40], [-80, 30], [-90, 40], [-70, 40]]

Dpoint

💡 Hint

Common Mistakes

Using 'point' type for polygons.

Not nesting coordinates correctly as an array of arrays.

The polygon type requires coordinates as an array of linear rings (arrays of points). The outer array wraps the ring.

5fill in blank

hard

Fill all three blanks to define a geo-shape circle with the correct type, coordinates, and radius.

Elasticsearch

{
  "area": {
    "type": "[1]",
    "coordinates": [2],
    "radius": "[3]"
  }
}

Drag options to blanks, or click blank then click option'

Acircle

B[-77.03653, 38.897676]

C100m

Dpolygon

Attempts:

💡 Hint

Common Mistakes

Using 'polygon' type for circles.

Providing radius without units.

Swapping latitude and longitude in coordinates.

A geo-shape circle requires type as 'circle', coordinates as [longitude, latitude], and radius as a string with units.
