geo_radius

DPU:

0.5

Purpose:

To filter for posts originating inside a circle. You specify the radius of the circle in kilometers (km) and the center as a pair of latitude and longitude coordinates.

1 mile = 1.6 km.

Case:

Not case sensitive.

Syntax:

geo_radius(latitude, longitude : radius)

Note the use of the comma and colon. Spaces and new lines in the argument are ignored.

Examples:

  1. Filter for clicks on bitly links from users within 50 kilometers of Reading:

    bitly.geo geo_radius "51.4553,-0.9689:50"

  2. Filter for clicks on bitly links from users within 250 kilometers of New York City:

    bitly.geo geo_radius "40.78, -73.97:250"

  3. Filter for interactions originating within 50 kilometers of the 10 largest US cities. Notice that we have tagged each output object, adding location metadata that can be analyzed by your client code:
