◆ can_be_modified_to()

bool dd::Spatial_reference_system_impl::can_be_modified_to ( const Spatial_reference_system srs) const
inlineoverridevirtual

Checks if this SRS can be changed to another SRS definition without changing any computations.

It's not allowed to change any numbers that affect computations, but it is allowed to add TOWGS84 parameters if the SRS doesn't already have any.

Parameters
[in]srsThe SRS to compare with.
Return values
trueThe two SRSs are semantically the same.
falseThe two SRss are not semantically the same, or of types which comparison rules are unknown (e.g., unknown projection).
