Help in complex Search Query alert

The context is Splunk is collecting data from a radar device.

Basically what it gets is the Latitude, Longitude and Id of nearby objects in a meters radius range.

The events are in JSON format and the following is an exemple:

 

 

{
  "Id": 1,
  "Latitude": x,
  "Longitude": y
}

 

 

Splunk must trigger an alert when an object which previously was at position y, now is at position z iff delta z-y is too big.

I know the alert can be triggered if the search result returns at least 1 row, but I don't know how to write this query because too complex.

Is it possibile to make this query? How can I do this?
Thank you in advance!

The JSON object only has 3 elements - of two events for the same id, how  do you determine which was the previous. Given two events for the same id, how do you determine the diff between two events especially since these look like locations on a sphere?

Sorry you are right, I forgot to specify the JSON includes the timestamp too.
