Geocode functions

The geocode data type contains the longitude and latitude values that represent a geocode property.

Note that all distances are expressed in kilometers.

Function	Description
`LATITUDE(mdex:geocode)`	Returns the latitude of a geocode as a floating-point number.
`LONGITUDE(mdex:geocode)`	Returns the longitude of a geocode as a floating-point number.
`DISTANCE(mdex:geocode, mdex:geocode)`	Returns the distance (in kilometers) between the two geocodes, using the haversine formula.
`TO_GEOCODE(mdex:double, mdex:double)`	Creates a geocode from the given latitude and longitude.

The following example enables the display of a map with a pin for each location where a claim has been filed:

RETURN Result AS
SELECT
	LATITUDE(geo) AS Lat,
	LONGITUDE(geo) AS Lon,
	DISTANCE(geo, TO_GEOCODE(42.37, 71.13)) AS DistanceFromCambridge
WHERE
	DISTANCE(geo, TO_GEOCODE(42.37, 71.13)) BETWEEN 1 AND 10

Note: All distances are expressed in kilometers.
