Q & A

What is the main topic of the lecture for NAV 6 Module 2 Week 9?

The main topic of the lecture is the basic standard function of ECDIS (Electronic Chart Display and Information System) as a continuation from the previous week's topic.

How do you open the chart panel in ECDIS?

You open the chart panel by selecting the appropriate line of the task list menu on the control panel.

What is the purpose of the tab in the left part of the chart panel?

The tab in the left part of the chart panel is used to switch between the complete list or back position, depending on which chart is required to be found.

What happens when you select a chart number and press enter?

When you select a chart number and press enter, the chart details such as chart number, scale, original scale, issue date, last correction, and format will be displayed.

What does the message 'No chart found' or 'Partial match found' indicate?

The message 'No chart found' indicates that no chart matches the entered number. 'Partial match found' means a group of charts has been found that starts with the entered character.

How can you load a chart in ECDIS?

You can load a chart by typing the chart number, highlighting it, and then pressing the 'Load Chart' button, which will display the chart in the chart area.

What is the function of the 'Chart Autoload' button in the General page of the chart panel?

The 'Chart Autoload' button is used to turn on the chart autoload mode, which automatically loads the largest scale chart available.

What does the 'Chart Fixing Mode' do in ECDIS?

The 'Chart Fixing Mode' keeps the chart fixed until the loading mode is switched off, meaning the chart remains loaded even if the vessel moves or another chart is manually loaded.

What is the difference between 'Auto Scale' and 'Off' in the chart scaling mode?

With 'Auto Scale' on, the chart is loaded on its original scale. When 'Off', the chart is loaded on the screen's current scale, maintaining the same scale as the previous chart.

What is the purpose of the 'Priority Chart' setting?

The 'Priority Chart' setting determines which type of chart to load first, such as ENC (Electronic Navigational Chart), DNC (Digital Navigational Chart), or HCF (Hydrographic Chart Raster Format).

How does the 'Conditional Symbolization' feature work in ECDIS?

Conditional Symbolization controls the display of certain objects, such as isolated rocks, based on safety contour settings. If an object is within the safety contour, it may not be displayed to prevent the vessel from entering a shallow area.

What is the Electronic Range and Bearing Line (ERBL) and how is it used?

The Electronic Range and Bearing Line (ERBL) is a tool used to measure the direction and distance from the vessel to a point. It can be activated and used to display information about the range and bearing on the ECDIS.

Keywords

💡EIS

EIS stands for Electronic Information System, which is a computer-based system utilized on ships for navigation and management purposes. In the context of the video, EIS is integral as it is the platform through which various navigational tasks are performed, including chart handling and information retrieval. The script mentions EIS in relation to its basic functions and operations, emphasizing its role in maritime navigation.

💡Chart Panel

The Chart Panel is a component of the EIS that allows users to access and manage navigational charts. The script describes how to open the chart panel through the control panel menu and how it can be used to search for and load charts. It is a critical tool for navigating as it provides essential information about the sea and coastal areas.

💡Chart Search

Chart Search refers to the process of finding specific charts within the EIS system. The script explains how to initiate a search by typing a chart number and how the system responds with results, either showing the chart details or indicating that no chart was found. This feature is crucial for quickly accessing the necessary navigational charts for a ship's route.

💡Autoload

Autoload in the context of the video refers to the automatic loading of charts based on certain criteria, such as the largest scale available. The script mentions an 'autoload mode' that can be turned on or off, which affects how charts are displayed on the EIS. This feature streamlines the process of chart management, ensuring that the most appropriate chart is always visible.

💡Scale

Scale in navigation refers to the ratio of a distance on the chart to the actual distance on the ground. The script discusses the importance of scale in chart loading, mentioning 'original scale' and 'current scale'. Understanding scale is essential for accurate navigation as it helps mariners to interpret the size and distance of features on a chart correctly.

💡ENC

ENC stands for Electronic Navigational Chart, a digital vector format used for marine navigation. The script specifies ENC as a priority in chart loading, indicating its common use in maritime navigation. ENCs provide detailed and up-to-date information about the marine environment, which is critical for safe navigation.

💡DNC

DNC stands for Digital Navigational Chart, which is a raster format used primarily by military vessels. The script distinguishes DNC from ENC, noting that it is used less commonly but is still an option within the EIS. DNC charts are similar to traditional paper charts but in a digital format, offering a different level of detail and functionality.

💡Safety Contour

Safety Contour is a feature in the EIS that determines which objects, like isolated rocks, are displayed based on their depth relative to a set safety depth. The script uses the example of an isolated rock to explain how objects within a certain depth are considered safe and thus not highlighted as dangers. This feature aids in navigating by highlighting potential hazards.

💡ERB

ERB stands for Electronic Range and Bearing line, a tool used for measuring distances and directions electronically. The script describes how to activate the ERB feature within the EIS, which then allows for dynamic measurement of distances and bearings from a selected point, typically the ship's position. This tool is valuable for precise navigational calculations.

💡Conditional Symbolization

Conditional Symbolization refers to the display of certain objects or features on a chart based on specific conditions or settings. The script explains that the visibility of objects like isolated rocks can be controlled by settings such as the safety contour. This feature allows navigators to customize the information displayed on their charts to match their safety requirements and preferences.

💡Parallel Index Line

A Parallel Index Line is a tool used for plotting or measuring courses and is mentioned in the script as a feature that can be demonstrated within the EIS. It allows navigators to draw lines parallel to a ship's course, which is useful for planning and checking navigational routes, especially in confined waterways like river channels.

of module 2 so we are now on the midterm

again I am second mate evaristo

Feliciano Okay so our learning outcome

is to demonstrate the basic standard

function of eis as a continuation from

the last week Uh module or last week

topic So this is again basic

operation so what We are going to

discuss now Uh guys is the prom search

and loading of chart that is handling

chart and chart information now to open

Uh the chart panel is by selecting the

appropriate line of task list menu on

the control panel so nasa kanan yan pag

binuksan niyo yung control panel lalabas

yan i- select lang yung chars okay

ngayon pagbukas ng charts Ito na ang

lalabas Okay so use the tab in the left

part of chart panel ito yung chart panel

which will open up to switch to complete

list or back

position Okay ito yan complete L or by

position so depending on which chart is

required to be found all the function of

these pages are identical So halos Paras

lang naman yung function niya The only

difference between them being in the set

of charts available for work so yun lang

mga mapa na dedepende na yan

kung ilang mapa ang nakad sa ating so

ito yan

Okay so pag select mo nag enter ka rito

halimbawa ng chart number so pag find

lalabas na yan

dito Okay so pagka Walang nakita ay

lalabas yyung message no chart found or

partial match found ibig sabihin a group

of chart has been found number start

with the entered character so hindi

naman buo ito ita-type mo yung una lang

Lalabas na yan okay pag pine mo lalabas

na siya Okay so ano yung makikita natin

dito yung kanyang chart number scale

yung scale niya kung ano yung kanyang

original scale ano yung issue date niya

last correction niya at saka yung format

ng chart So yun ang lalabas

Dian okay ngayon pagka nagf nga

tayo

pinindot natin onong find nag-type tayo

dito ng chart

number so ito yung lalabas na

diyan so the type of the number Ayan na

tinype mo lalabas na rito so

mag-highlight na siya and then kung

gusto mong i-load yan pindutin mo lang

Ong load chart lalabas na doon sa chart

area natin So lalabas na

siya Okay so ganun lang naman kasimple

yung ah pag-load ng chart Okay on the

tab on the right hand part so right hand

part sa kanang bahagi ay meron siyang

chart panel yung chart panel niya right

hand part A It will open to general page

So may layer enc na-discuss na natin yan

nakaraan yung layer and enc so dito muna

tayo sa General page so sa General page

mayong chart Autoload yan so chart

loading mode switching button yan So ano

yung

Uh available so meron

tayong

on okay to turn on the chart Autoload

mode so usually Uh the largest scale

chart will be automatically loaded so

yan ang magandang setting on okay pag

in-off mo naman okay now the current

chart under the sh position o kung

nasaan yung barko or the chart loaded

manually is fix until the loading mode

switch so nandon yung mapa yun pa rin

ang

naka-ads ka uli or mag-load ka ng chart

na

manual Okay so yan yung sa off natin and

then meron ka namang fix

diyan fix So this Turn on the chart

fixing mode as the shift symbol crosses

the Boundary of sa chart chart the chart

loading mode is automatically switch to

the on

position so magaa yan mag-switch siya sa

on position tapos iload niya yung chart

So parang Parehas lang din ng ng on yan

yung

Autoload okay now

yung auto scale makita natin diyan sa

baba aut scale chart scaling mode naman

yan So yung chart scaling mode to load

the chart on original scale so iload ni

naman niya doon sa original scale niya

okay pag naka-off ito yung off niya

napindot yan okay to load the chart on

the screen current scale So kung ano

yung current scale ng chart i-maintain

niya yun p naka

off Okay and then meron ding scale ratio

yan So yung ating scale ratio Set the

loaded chart scale different from each

or scale So yung pag nag-load siya ng

chart kung ano yung scale ratio mo 1 is

1 1 is 2 zero ay wala siya default niya

yan parang naka-off din siya okay zero

So ibig sabihin yung Ah yung chart niya

iload niya doon sa

scale okay yung sa scale na nandoon kung

ano yung scale nung nung mapa mo So pag

naglagay ka ng one then That Is 1 is to

one so hanggang five yan yung scale so

yan yung gusto mo kung anong gusto mong

ah ratio Okay so sa ibaba naman meron

tayong priority chart so meron tayong

enc ayan Meron tayong Ayan ang kalimitan

na ginagamit natin

enc electronic navigational chart yan

ang priority natin pag XD ang ginagamit

tandaan na yan ang ginagamit natin okay

dnc that is to load the dnc vector chart

o yung digital navigational chart

ginagamit yan mostly ng mga military

vessel mga Navy ship Ayan ginagamit yan

military ship Okay so ito namang

hcf yan yung

hydrographic chart raster format

hydrographic chart raster format ito ung

naglo-load ng arcs and CP format raster

chart so ung admiral raster chart

services ng mga mapa Andiyan yan kung

yan ang gusto mo maging priority so sa

barko ay normal yung

enc Okay yyung

hcf hydrographic chart raster format

review so pag pinindot mo yan ay lalabas

ung ung chart na naayon re-review niya

re-review natin kung gusto mong tignan

Okay Yun ang mangyayari diyan yan ung ah

review Okay so the Uh chart assistance

open the chart assistant

window Okay so yung chart assistant

window Nandiyan din yung tayo ay mag ah

mag a-update ng chart Nandiyan din yung

chart

assistant All

right let's continue okay Meron siyang

button yung chart Autoload pag pinindot

mo y button na yan magre-react

doon sa control panel merong chart area

ito yung tinatawag natin na chart area

doon sa kanan sa sidebar ng ating yung

sidebar yung mga control button doon

halo-halo na merong mga mga display ng

data lahat na nandoon mga mga control

mga option merong chart area kang

makikita rito so may mga information yan

diyan makikita kung ano yung option ba

in-off mo ma-off yan kung in-on mo ma-on

yan ngayon naka-off to ibig sabihin

sinet mo to ng off Okay so yung off eh

nak naka ung Autoload niya

naka-off So yun ung magiging ah ano mo

ah view mo o indicator mo siya na na-off

siya doon sa

setting Okay doon sa setting ng chart

loading ng chart Okay Ayan tapos

ah ayan ito yung ilalim pag na-off

Makikita mo mag-o-off siya okay pag

nag-off siya pwede kang mamili na

ng ng mapa mo kung ano ung chart mo dito

na so naka-off kasi eh so mano-mano ang

loading mo ngayon okay ikaw maglo-load

so mas maganda ay naka-auto yan palagi

naka-on yan ang pinakamagandang setting

Okay yan then selecting loading priority

ito na yun na-discuss na natin kanina

yan so ang common sa atin ay enc Okay

enc Hindi hcf ha

enc

okay Doon naman sa chart Autoload Ayan

naka-on press on yung p pinindot mo yung

on dapat yung chart auto scale

recommended ay naka-on din Hwag mong

kokontrahin para mas maganda siyang

kombinasyon nagool load yung chart yung

a yung scale niya nagool load din So

pwede mo ring i-off yung ah chart auto

scale so hindi siya maglo-load doun sa

sa original scale niya So kung ano yung

scale nung previ na mapa yun ang

maintain

ni okay ngayon pag naka-off yun yung

yung auto scale in-off mo ikaw mamimili

ng scale ratio mo diyan Okay Yun yung

scale ratio natin kanina pinakita do yan

sa chart

panel Okay yan tapos ito yan Makikita mo

naka-off siya yung chart auto scale yan

mabubuksan mo yan at ikaw bahala pumili

ng scale na gusto mo Okay so ganiyan

lang naman yan Alright ngayon doon sa

ating Uh

Uh display ng mapa May makikita tayo

doon na setting ng conditional

symbolization of certain object class so

paliwanag ko lang ' yung conditional

symbolization yung symbol halimbawa

isolated rock dedepende yan yung ah kung

lalabas yan o hindi Depende sa setting

mo ng safety contour so ung safety

contour kino-consider natin as nogo area

ibig sabihin hindi yan papasukin ng

barko pag ikaw naglagay diyan Bawal kang

pumasok kasi ibig sabihin niyan Ay

mababaw SAO yan So yung mga isolated

rock na na halimbawa 14 m nasa loob siya

So protektado ka diyan so bale wala na

to kasi ito na yung babantayan ng barko

mo sa ecdis babantayan ni eis yan Ito na

hindi na ito okay in case ito mas mataas

sa 20 m halimbawa ito 25 m

to Okay So ibig sabihin nasa labas siya

ng safety contour o babantay to lilitaw

ngayon to Ayan danger sa ito kasi

Nakabukod Okay halimbawa lang halimbawa

lang

ha Okay so that will be a a danger Ay

hindi pala Sorry Ito pala pagka mas

mataas to an ba mas malalim Siya nasa

labas siya okay

so hindi siya ah danger SAO so danger

siya sayo pag na tinamaan siya ng 20 m

kasi nasa loob ngayon irrelevant din yon

dahil protektado ka na ngayon pag nasa

labas siya mas malalim siya ibig sabihin

ah 25 m malalim naman SAO ion h ka

tatamaan non so Okay lang yung isolated

danger hindi nalil yun na danger SAO

Okay so lilitaw yun dito sa 20 meters

kaya lang protektado ka na nga pag ka

lang

papasok Okay so

next Okay setting tayo ng

arbl cursor Iyung ebl electronic range

and bearing line electronic na siya ayan

yan dito yan ayan oh bearing ito yyung

range yung bilog Okay pwedeng galing sa

barko pwedeng i-offset mo yan dadalhin

mo yan doon yung

ebl Okay dito sa laboratory natin diemon

rate ko na yan yung ah pag offset niya

doon sa ating laboratory so sa

laboratory niyo na makikita yan kung

papaano yan ino-off doon sa ating

eis Okay

so pagka lumabas na yan na-activate niyo

yan lalabas yung information ng erv sa

bandang ilalim Ayan on the bottom part

may lalabas na ganito na window so pag

ginagalaw mo yung ebl brm dito yan

gagalaw

Ito okay yan gagalaw yan So may lalabas

yan pag na-activate yung er vl Okay

Paano ba i-activate

Okay pupunta ka system information yan

diyan sa display panel Sa right side yan

then Nakikita mo yung

erb Okay diyan sa control panel diyan

dito sa Ito yung control panel yung

pinakabayan

yung display panel yun lalabas Ito okay

so buo yung control panel yan nasa kanan

yan okay yung sidebar then yung display

panel makita mo pag binuksan mo yan

click mo lalabas yung

er BL Okay tsaka brm yung electronic

bearing line yan yung bearing line yung

guhit yung direksyon yung brm yan yung

bilog yan yung yun yung sukat ng layo

distance si variable range marker So

diyan mo i-activate ngayon pag

na-activate mo ito na yung lalabas na

control doon sa sidebar doon sa control

panel lalabas yan so ito yan

lalabas

Okay so aan i-activate mo na siya A1 vm1

yan ay dinonate ko na yan doon sa

laboratory natin ng nakaraan ng week 8 I

think week 8 so week 9 na ngayon

Okay Ayan Yan so ebl dalawa yan V ebl 2

brm

2 Okay so pag inoff yung offset na yan

ay lilipat mula sa barko yung source ng

ebl brm mo lilipat kung saan mo gusto

ilagay so na-off yang parehas ebl 1 vm1

saka yyung ebl 2 brm

2 Okay so yan

yan Okay ito namang line one ah line two

yan yung parel

index line so diemon ko na rin yan doon

sa ating laboratory kung papaano gamitin

yung ah parallel index line Okay so may

line one and line two so yyung direksyon

niya ito Ito naman yung range layo niya

mula sa barko Okay kaya dalawa starboard

n4

so Kanan ng barko kaliwa ng barko pwede

mong

gamitin Okay so yan at ginagamit yan ay

protek sa atin kung hanggang saan yung

limit natin yung guide natin yan lalo na

sa river channel channeling ay gamit na

gamit yan Okay emon natin yan

pagka sa laboratory

dedemon

All

right Okay

so yung teaching and learning activities

natin ay dito sa lecture ay recitation

so isulat niyo lang lahat yung mga

topics Hindi na kailangan yung mga

procedure mga topic sa papel picturan

niyo i-turn in niyo kasama nung picture

na o screenshot na pinanonood niyo yung

video na ito at pinanonood niyo So pwede

naman yung screenshot lang nung video

natin na ito ng lecture Okay tapos

ngayon
