HIPS supports a standard Canadian Hydrographic Service tide format called COWLIS as well as two NOS/NOAA formats. HIPS also supports a basic format consisting of just the required date, time, and tide values.
HIPS does not use predicted tide tables. The time zone of the tidal observation data must match the time zone of the bathymetry to which it will be applied.
As an alternative, a Computed GPS Tide calculation can be used with data in HIPS
