Heights
Height of tide is the vertical distance between the surface of the sea and chart datum.
Datums
Chart datum is the plane of vertical reference to which all charted depths and drying heights are related. More info
| Vertical Datum | Offset (m) |
|---|---|
| IGLD85 | 173.50 |
The information contained in this product is established under the CD datum. The CHS does not establish and maintain other vertical datums such as CGVD28, CGVD2013, IGLD (1955) and IGLD (1985). References to these datums represent the best available information, to be used with caution and sound judgment where required, but it is not intended to be used for navigation.
