Overview

This is a base class for all OGC coordinate system objects. This includes both interfaces and data types from the OGC Coordinate Transformation spec.

This is a non-instantiable abstract class.

#eql?(rhs_) ⇒ Boolean Also known as: ==

Tests for equality. Two objects are defined as equal if they have the same type (class) and the same WKT representation.

Returns:

  • (Boolean)

#to_wkt(opts_ = {}) ⇒ Object

Computes the WKT representation. Options include:

:standard_brackets

If set to true, outputs parentheses rather than square brackets. Default is false.
