Determines if the specified object or location crosses a geographic location specified by geo.json.geometry.fence.
Syntax
<BOOL> geo:crosses(<STRING> id, <DOUBLE> longitude, <DOUBLE> latitude, <STRING> geo.json.geometry.fence)
<BOOL> geo:crosses(<STRING> id, <STRING> geo.json.geometry, <STRING> geo.json.geometry.fence)
Query Parameters
| Name | Description | Possible Data Types | Optional | Dynamic |
|---|---|---|---|---|
| id | Location ID. | STRING | No | No |
| longitude | Longitude of the geo location. | DOUBLE | Yes | No |
| latitude | Latitude of the geo location. | DOUBLE | Yes | No |
| geo.json.geometry | String that contains geometry type and coordinates for a GeoJSON geometry. | STRING | Yes | No |
| geo.json.geometry.fence | String that contains geometry type and coordinates for a GeoJSON geometry fence. | STRING | No | No |
Example
geo:crosses(km-4354, -0.5, 0.5, {'type':'Polygon','coordinates':[[[0, 0],[2, 0],[2, 1],[0, 1],[0, 0]]]} )
This example returns true because the coordinates cross the geo.json.geometry.fence.
