region property
Specifies the region code, specified as a ccTLD ("top-level domain") two-character value.
You can set the Directions service to return results from
a specific region by using the region
parameter. This
parameter takes a ccTLD (country code top-level domain)
argument specifying the region bias. Most ccTLD codes are
identical to ISO 3166-1 codes, with some notable exceptions.
For example, the United Kingdom's ccTLD is "uk" (.co.uk
)
while its ISO 3166-1 code is "gb" (technically for the entity
of "The United Kingdom of Great Britain and Northern Ireland").
You may utilize any domain in which the main Google Maps application has launched driving directions.
