Riferimento Datum di Marea

Cerca 2.200+ stazioni mareografiche NOAA per le tabelle complete dei datum di marea — MHHW, MHW, MSL, MLW, MLLW (chart datum), escursione di marea e relazione NAVD88. Riferimento essenziale per topografi idrografici e costieri. Gratis.

Un datum di marea è un'elevazione standard definita da una fase della marea, usata come riferimento per misurare i livelli e le quote locali dell'acqua. Il chart datum (Mean Lower Low Water negli USA) è lo zero delle carte nautiche. I topografi idrografici riducono gli scandagli al chart datum; gli ingegneri costieri relazionano le strutture a MHHW o NAVD88. Cerca qualsiasi stazione NOAA qui sotto per la sua tabella ufficiale dei datum.
