TGIS_CSAbstract class
DK for .NET | TatukGIS.NDK.TGIS_CSAbstract | Classes | Constructors | Methods | Properties
Base class for any WKT coordinate system units (ellipsoids, datums, prime meridians, units). Manages EPSG codes, WKT names, and metadata for coordinate system definitions.

Remarks
PURPOSE:Provide abstract foundation for all coordinate system definition elements (units, ellipsoids, datums, etc.), ensuring consistent EPSG numbering, WKT representation, and deprecation tracking across the CS framework.
BEHAVIOR:Stores EPSG code (unique ID), optional alias MasterEPSG for deprecated definitions, WKT name string, and deprecated flag. Subclasses override fget_Description and fget_FriendlyName to provide specialized formatting. EPSG numbering: 1-99999 official EPSG, 100000-199999 TatukGIS custom, 7000000+ dynamically assigned.
USAGE:Never instantiated directly; use subclasses (TGIS_CSEllipsoid, TGIS_CSDatum, TGIS_CSUnits, etc.). Access via EPSG code lookups in coordinate system factory methods. Check Deprecated property before using in new projects.
CONSTRAINTS:Abstract base class; instantiation requires concrete subclass. EPSG codes must be unique within their category. WKT field must follow WKT standard format for serialization.
