Tide Data Manager (QINSy version 8.1)
*Time issue between tide data and survey line data.
*Tips to correct the incorrect time zone in survey line data.
- Job done in Malaysia, but time zone is UTC:
- in Malaysia +8:00, so if survey data line start at 2:00am in 26 Aug, add 8 hours = 10:00am is the actual survey line data start time, and still in 26 Aug.
- so apply tide in tide data manager (manual method) by select 26 Aug, and 8:00am first tide data (depend on when tide is first collected, but must always before survey line data time!) and end time lets say the tide is last collected at 16:00pm on the same day.
-so we have 2 hours early from survey line data start time, this will give extra tide info as long as tide is collected before start survey till we end the survey job.
-QINSy can now process the tide data by tally the tide value with the survey line data value by refering to time of the data.
