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.

Transcripts
Hell Good day gentlemen so we are again
here in our lecture for nav 6 and this
is for module 9 Sorry module 2 week 9
that is again module 2 week 9 or week 9
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
ay tapos na yung quiz assignment naman
So May assignment kayo gawin niyo na
lang okay guys thank you very much for
listening Have a good day
