intersects (Function)

Two available sets of parameters:

• First set returns true if the incoming geo.json.geometry event intersects the given geo.json.geometryFence.
• Second set returns true if the specified coordinates intersect the given geo.json.geometryFence.

Syntax

<BOOL> geo:intersects(<DOUBLE> longitude, <DOUBLE> latitude, <STRING> geo.json.geometry.fence)
<BOOL> geo:intersects(<STRING> geo.json.geometry, <STRING> geo.json.geometry.fence)

Query Parameters

Name	Description	Possible Data Types	Optional	Dynamic
longitude	Longitude of the geo location.	DOUBLE	Yes	Yes
latitude	Latitude of the geo location.	DOUBLE	Yes	Yes
geo.json.geometry	String that contains geometry type and coordinates for a GeoJSON geometry.	STRING	Yes	Yes
geo.json.geometry.fence	String that contains geometry type and coordinates for a GeoJSON geometry fence.	String	No	Yes

Example 1

geo:intersects( {'type':'Polygon','coordinates':[[[0.5, 0.5],[0.5, 1.5],[1.5, 1.5],[1.5, 0.5],[0.5, 0.5]]]} , {'type':'Polygon','coordinates':[[[0, 0],[0, 1],[1, 1],[1, 0],[0, 0]]]} )

This example returns true because geo.json.geometry intersects with geo.json.geometry.fence.

Example 2

geo:intersects(0.5. 0.5 , {'type':'Polygon','coordinates':[[[0, 0],[0, 1],[1, 1],[1, 0],[0, 0]]]})

This example returns true because the coordinates intersect with geo.json.geometry.fence.
