The height should be given in metres (xx.x) with a resolution of 0.1 metre.
Format:
CCYYMMDDThhmm,xx.x,CCYYMMDDThhmm,xx.x
Example:
19950428T1020,1.2,19950428T1455,4.8,...
Remarks:
The attribute 'tide - high and low water values' encodes information on the times and heights of
high
and low waters for each day of the duration of the time series.
Attribute: Tide - time and height differences
Acronym: T_THDF Code: 164
Attribute type: A
Indication:
time difference in hours and minutes: " hhmm (according to ISO 8106: 1988)
height difference: metres (preceded with A-@ if negative value)
rate difference: knots (preceded with A-@ if negative value)
Example:
Tidal height: 63230, Darwin,-0040,-0.7,0.9
Tidal stream: 59060, Cairns,+0130,1.2,-0.7
Remarks:
The attribute 'tide - time and height differences' encodes the time and tidal height or tidal stream
rate
difference comparative to a reference station.
The format is the same for tides and tidal streams, with height difference being replaced by rate
difference. The relation to a reference station is encoded by the use of a collection object.
The attribute is used to contain the identification of the reference station and , encoded in
triplets,
mean time difference (+ or -), height or rate difference for mean high water or mean high rate
(preceded with A-@ if negative value), height or rate difference for mean low water or mean
low rate
(preceded with A-@ if negative value), each value separated by a comma.
Attribute: Time end
Acronym: TIMEND Code: 168
