+Specify whether the vertical coordinates in the SEG-Y file are heights
+(positive up) or depths (positive down). By default, the vertical
+coordinates are treated as heights (i.e. positive up). This means that the
+Z-axis of the dataset goes from 0 (surface) to -ve depth (last sample).
+Note. As per the SEG-Y rev 2.0 specification, this information is defined
+in the Location Data Stanza of the Extended Textual Header. However, as of
+this revision, SegYReader does not support reading the extended
+textual header.
