-Coordinate Reference System (CRS) Representation
-................................................................................

-Well Known Text (WKT) is the required Coordinate
-Reference System (CRS) representation for LAS 1.5. 
-
-A "WKT" bit is included in the :ref:`Global Encoding <globalencoding_link>` field in the Public Header
-Block. This bit must be set for LAS 1.5; GeoTIFF CRS definitions for legacy
-point formats are no longer supported in LAS 1.5. The CRS for the file must be 
-located in the WKT (Extended) Variable Length Records (EVLR, VLR).
-
-It is considered a file error to have more than 
-one WKT (E)VLR in the file. A writer can append a new CRS EVLR to a file by
-"superseding" the existing CRS (E)VLR. Superseding is performed by changing the
-Record ID of the (E)VLR to match the :ref:`superseded_vlr_label` VLR defined
-later in this document.
