Tide Observation and Chart Datum 16

• Comprehend the importance of tide observation to produce ENCs.

• Need close cooperation with the Littoral States for collecting tidal data.

• Ask the Littoral States to make us visit temporary tide stations with officials.

In the tidal corrections, the Zo zone divided into 1cm increment interpolated from the 10 cm standard zone shall be identified.

Chart Datum Level (CDL))=MSL-Z0

Technical Approach - Installation of Equipment -

Example of Installation of Survey Equipment

High quality, low noise data can only be acquired by the rigid installation of Transducer/equipment onto the hull

Non-prism laser rangefinder - - Measurements of nav - aids

Technical Approach - Equipment and Software -

Digital Hydrographic Survey Data Acquisition System (DHSDAS)

19

Technical Approach - Data Acquisition -

Setting various parameters for DHSDAS

• Accuracy of survey ship’s position is within 1m. • Sounding Accuracy is kept within 1a of S-44. • Data Acquisition time is the International Standard Time. • HYPACK SURVEY & HYSEEP Software are used of Data acquisition.

＊ Carry out the MB sounding by round trip in the TSS of the one way route. Prior to the survey, We notify the each sounding area in advance and would like to request to issue Notice to Marinas & Navigation Warning to HOs

• Plan parallel sounding line along contour line • Measure of each layer’s Sound Velocity in

water by SVP meter • Acquire good S/N depth data in order to get

high quality depth • Synchronize output time between each

Technical Approach - Data Processing -

c) Area-based data processing

Filtering by“ 0.5 2 + (0.013 × 𝐝𝐞𝐩𝐭𝐡)2

a) line survey noise deletion data processing b) Comparison with adjacent sounding and cross line

Verification of overall depth data • Combine the "XYZ file" of each survey line file, • Create a "intermediate XYZ File" of the entire survey area • Create and "three-dimensional bird's-eye view DTM file“ & “1m Contour file“ • Examine unnatural depths relate to continuity and geomorphology of the adjacent

survey line on "1m Contour file" and "three-dimensional bird's-eye view DTM file“ • Examine the consistency by collating the existing charts

24

Example 2 (process of noise reduction)

Technical Approach - Data Processing -

Methodology of Creating fair sheet file and Selecting radius sorting

25

Technical Approach - Creating Fair Sheet file-

The Fair Sheet (file) is created by considering a suitable scale for ENC compilation in response to request of the littoral State as following method.

• To create "SOUNDG_5m" from "MBES sounding edit file“ • To create "SOUNDG" file of the density to describe the depth in

Fair sheet by using HYPACK sort function from "SOUNDG_5m“ • To create contour file "DEPCNT“ by TIN function of HYPACK from

"SOUNDG_5m in automatic processing. • To create a "SURVEY_AREA" from "SOUNDG_5m“ • Create Fair Sheet file (XYZ format) using "SOUNDG", "DEPCNT“,

"SURVEY_AREA" and Nav-Aid file • To create Data Processing Report in a series of data processing

• Investigate variation/change of remarkable Sand Wave area by comparison with previous data of same SW area.

• Capture a soaring phenomenon of sand in digital and analog records at the top of Sand Wave terrain at the time of strong tidal current of Spring tide, and check the difference of them.

• Positioning measurement of Navigation buoys using non-prism laser from survey vessel in the survey area.

Suggestions 29

Aero Asahi Corporation will

• Observe administrative requirements of the Littoral States

• Communicate frequently with observers

• Do strictly management of all acquired and processed data

Aero Asahi Corporation appreciate if the HSTWG meeting approves Aero Asahi Corporation as an appropriate survey company to be participated in this significant project.

Thank you for your attention !
