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

Who Carry's out Reconnaissance

Carried out by a Senior Surveyor/Charge Surveyor

Reconnaissance Phases

Office phase and field phase


Office phase

Reconnaissance phase,


Gathering required data ie. Topographic maps, Aerial photographs and geodetic stations in the area

Field phase

Reconnaissance phase


Visiting the area, finding spots for tidal or positioning sites

Established Reconissance Tasks

- Geodetic sites (known position points)


- Accommodation for shore party


- landing sites for RHIB


- Establishing local relationships

HI/ CONTRACT Storage (not the list)

Who checks LINZ survey reports

Charge Surveyor

Pre-Survey (Plan) order of events

○ Hydrographic instruction Received


○ Planning Chart constructed, system initialized


○ Reconnaissance of survey area


○ Stores uplifted


○ Calibrate and check gear


○Tidal stations & Geodetic stations established.


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'
