The set of {@linkplain DefaultCoordinateSystemAxis coordinate system axes} that spans a given coordinate space.The type of the coordinate system implies the set of mathematical rules for calculating geometric properties like angles, distances and surfaces.

This class is conceptually abstract, even if it is technically possible to instantiate it. Typical applications should create instances of the most specific subclass with {@code Default} prefix instead.An exception to this rule may occurs when it is not possible to identify the exact type. For example it is not possible to infer the exact coordinate system from Well Known Text (WKT) version 1 in some cases (e.g. in a {@code LOCAL_CS} element). In such exceptional situation, a plain {@code AbstractCS} object may beinstantiated.

{@section Immutability and thread safety}This base class is immutable and thus thread-safe if the property values (not necessarily the map itself) and the {@link CoordinateSystemAxis} instances given to the constructor are also immutable. Most SIS subclasses andrelated classes are immutable under similar conditions. This means that unless otherwise noted in the javadoc, {@code CoordinateSystem} instances created using only SIS factories and static constants can be shared by manyobjects and passed between threads without synchronization. @author Martin Desruisseaux (IRD, Geomatys) @since 0.4 (derived from geotk-2.0) @version 0.4 @module @see DefaultCoordinateSystemAxis @see org.apache.sis.referencing.crs.AbstractCRS
