Reference documentation and code samples for the BigQuery Client class Geography.
Represents a value with a data type of Geography.
A value is expected to be in well-known text format, but there is no validation on client side.
Polygons are oriented.
It means that, for example, value POLYGON((0 0, 1 0, 1 1, 0 1, 0 0)) represents a (almost) square region,
and POLYGON((0 0, 0 1, 1 1, 1 0, 0 0)) represents the whole Earth surface except that square.
Example:
use Google\Cloud\BigQuery\BigQueryClient;
$bigQuery = new BigQueryClient();
$geography = $bigQuery->geography('POINT(30 60)');
