Using spatial types

3D point creation

Complete the following code to create a 3D point to represent the Burj Khalifa in Dubai.

python
from neo4j.spatial import WGS84Point

longitude = 55.296233
latitude = 25.276987
height = 828

point = WGS84Point(
  #select:(longitude, latitude, height)
)

  • ❏ (latitude, longitude, height)

  • ✓ (longitude, latitude, height)

  • ❏ point=(longitude, latitude, height)

  • ❏ WGS84Point.latlng(latitude, longitude, height)

Hint

The WGS84Point constructor takes coordinates in the order: longitude, latitude, height. The height parameter is optional but makes it a 3D point.

Solution

The correct answer is (longitude, latitude, height).

The following code creates a WGS84Point representing the Burj Khalifa in Dubai:

python
point = WGS84Point((longitude, latitude, height))

The coordinates must be provided in the order longitude, latitude, height. Including the height value creates a 3D point with an SRID of 4979.
