geodistance

The geodistance analytic returns the minimum distance between two geo points. A geo point represents the longitude and latitude coordinates.

Syntax

geodistance(latitude1, longitude1, latittude2, longitude2)

The following table describes the required and optional arguments:

Argument	Required Optional	Description
latitude1	Required	The value of the first latitude point.
longitude1	Required	The value of the first longitude point.
latitude2	Required	The value of the second latitude point.
longitude2	Required	The value of the second longitude point.

The following table provides the datatype for the parameters you can pass:

Parameter Input Options	Datatype
Event property	Real number
Watchlist values	Real number

Example

WHEN 1 boat b WITH geodistance(b.x1,b.y1,b.x2,b.y2) as distance =10 then response with 
body= “${distance}”

The following table describes the result for the event property value that you pass:

Event Property Value	Description	Result
b.x1=10 b.y1=10 b.x2=10 b.y2=20	Finds the distance between two geo points.	10
