ReQL command: line

Command syntax

r.line([lon1, lat1], [lon2, lat2], ...) → line
r.line(point1, point2, ...) → line

Description

Construct a geometry object of type Line. The line can be specified in one of two ways:

• Two or more two-item arrays, specifying latitude and longitude numbers of the line’s vertices;
• Two or more Point objects specifying the line’s vertices.

Longitude (−180 to 180) and latitude (−90 to 90) of vertices are plotted on a perfect sphere. See Geospatial support for more information on ReQL’s coordinate system.

Example: Define a line.

r.table('geo').insert({
    'id': 101,
    'route': r.line([-122.423246, 37.779388], [-121.886420, 37.329898])
}).run(conn)

Example: Define a line using an array of points.

You can use the args command to pass an array of Point objects (or latitude-longitude pairs) to line.

var route = [
    [-122.423246, 37.779388],
    [-121.886420, 37.329898]
]
r.table('geo').insert({
    'id': 102,
    'route': r.line(r.args(route))
}).run(conn)
