Sets the SRID copying behaviour. This value can be one of the values found in Geos::Constants::SRID_COPY_POLICIES and are local to the current thread. A special value of :default can also be used, which will use a global default that can be set with srid_copy_policy_default=. Setting this value will cause all future threads to use this global default rather than the true default value which is set to :zero for the sake of backwards compatibility with

The available values for policy are:

:default - use the value set with srid_copy_policy_default=, which itself is :zero.
:zero - set all SRIDs to 0. The only exception to this is when cloning a Geometry, in which the SRID is always copied as per the previous behaviour.
:lenient - when copying SRIDs, use the SRID of the object that the operation is being performed on, even if operation involves multiple Geometry objects that may have different SRIDs.
:strict - when copying SRIDs, raise a Geos::MixedSRIDsError exception if an operation is performed on mixed SRIDs. This setting
