Record Dates

The Horizontal, Ellipsoidal, Vertical, Geoid, MLLW, and History Tabs all have two parts to each tab.  The left side of each tab is a list of Record Dates.  The right side is the record itself.  When you select a specific record date on the left side of the tab, it displays the record for that date on the right side of the tab.   Important Note:  The most current date identifies the current control information.  Previous dates identify Superceded Control Information.
