Definition of hydrography |
The science of the measurement, description and mapping water of the earth, with special reference to their use for navigation. |
|
|
What is hydrographic surveying |
The collection of data of an area of sea and surrounding coastal detail to enable the cartographer to portray a part of the earths surface on a flat piece of paper and indicate by soundings, height and depth contours and spot heights the various irregularities both above and below the sea surface. |
|
|
P.O.S.S.D |
Position Orientation Scale Shape Detail |
|
|
Position |
At least 1 position must be known on the earth's surface to locate the survey, Found by - previous survey info - newly established by astronomical or satellite observations All collected positions are relative to this |
|
|
Orientation |
-Direction and Azimuth must be known - One position to another must be known -Direction between two points must be known or with 1 known position the sun can be used to observe for direction. |
|
|
Scale |
Distance between a minimum of two positions. - Direct measurement -By calculation with 2 known positions, known distance is the baseline and all others are relative. |
|
|
Shape |
Once Azimouth and scale is determined additional positions are coordinated to provide framework or detail |
|
|
Detail |
- Regular Depth seaward to shoreline - obtain and position least depth over shoals -coastline, HW,LW positions -nature of seabed - position of breakers/ tide tips ect - leading lights - Topographic details - tidal observations - tidal stream measurements - views - nav mark positions - sailing directions - wreck details - port information - - |
|
|
Hydrographic instructions |
(HI) -Used before LINZ establishment -issued by the hydrographic office/ hydrographer of New Zealand -HI's were replaced by a LINZ contract system |
|
|

Replaced Hydrographic Instructions when LINZ was established in 1995. |
|
|
HI or Contract format (A-M) |
- Introduction - limits of surveyed area - scale of conducted survey - the horizontal control - The vertical control- benchmark info - Sounding requirements - use of side scan sonar - Tidal data - Tidal stream Requirements - mischellaneous information -time frame/start/completion/Rendering - financial output code, cast centre, financial responsibility - Rendered data format Tidal data, coastline data, previous survey dates
|

|
6 steps |
|
Pre-Survey (Do) |
○Ship arrives in survey area ○Ships survey systems calibrated ○Sounding datum established ○Sounding data collection commences ○Sounding data checked ○All field equipment recovered |
6 steps |
|
Post survey (write the report) |
○ Write the report ○ Records collated, survey report completed ○ Hydrographer checks completed survey. ○ LINZ checks and validates survey. ○ Survey changes accepted or returned. ○ survey data used to check or revise a chart. |

|
Field records |
Need to be clean and clear and not regarded as rough. |
|
|
Principles of recording |
- completeness of information - intelligible layout - carefully checked - neatness and legibility - honestey and accuracy |
|
|
What dictates a complete record of information. |
-Title -Ships name -HI/Contract number -Type of instrument & Serial Number -Names of observers and recorders -Dates and times of observations -Diagrams or Sketches of routes taken or structures -Metrological conditions -Dimensions of targets and structures -Correct Nomenclature (local and correct name) - Any difficulties or unusual circumstances that occurred - |
|
|
What initiates good recording |
-Collect and record all information before observations start - HB Pencil - never erase or overwrite a mistake, - notes and figures printed - all recordings made as though it is a fair copy - second copy (if required) should be checked by another person and initialed correct. - all recording checked, approved and initialed by research observer |
|
|
Post survey Record checking, how to |
-All records and Data must be free of errors and ambiguity - Checked by an independent person (higher rank prefered) - If in doubt tell someone - your name, your reputation |
|
|
Ensuring observations are recorded accurately |
-Observer calls out reading -recorder writes it down -recorder reads back observation - Observer confirms reading -Recorder calculates reading -Recorder tells observer good or 'check' |
|
