Garmin GPSMAP 8000 Manuale Utente

Before you can view aerial photos on the Navigation chart, you 

must turn on the Photo setting in the chart setup.
NOTE: This feature is available with premium charts, in some 

areas.
You can use aerial photographs of landmarks, marinas, and 

harbors to help orient yourself to your surroundings or to 

acquaint yourself with a marina or a harbor prior to arrival.

From the Navigation chart, select a camera icon:
• To view an overhead photo, select 

.

• To view a perspective photo, select 

. The photo was 

taken from the location of the camera, pointed in the 

direction of the cone.

Select Review > Aerial Photo.

The Automatic Identification System (AIS) enables you to 

identify and track other vessels, and alerts you to area traffic. 

When connected to an external AIS device, the chartplotter can 

show some AIS information about other vessels that are within 

range, that are equipped with a transponder, and that are 

actively transmitting AIS information.
The information reported for each vessel includes the Maritime 

Mobile Service Identity (MMSI), location, GPS speed, GPS 

heading, time that has elapsed since the last position of the 

vessel was reported, nearest approach, and time to the nearest 

approach.
Some chartplotter models also support Blue Force Tracking. 

Vessels being tracked with Blue Force Tracking are indicated 

on the chartplotter with a blue-green color.

AIS vessel. The vessel is reporting AIS information. The 
direction in which the triangle is pointing indicates the 
direction in which the AIS vessel is moving.
Target is selected.

Target is activated. The target appears larger on the chart. A 
green line attached to the target indicates the heading of the 
target. The MMSI, speed, and direction of the vessel appear 
beneath the target, if the details setting has been set to 
Show. If the AIS transmission from the vessel is lost, a 
message banner appears.
Target is lost. A green X indicates that the AIS transmission 
from the vessel is lost, and the chartplotter displays a 
message banner asking whether the vessel should continue 
to be tracked. If you discontinue vessel tracking, the lost 
target symbol disappears from the chart or the 3D chart view.
Dangerous target in range. The target flashes while an alarm 
sounds and a message banner appears. After the alarm has 
been acknowledged, a solid red triangle with a red line 
attached to it indicates the location and the heading of the 
target. If the safe-zone collision alarm has been set to Off, the 
target flashes, but the audible alarm does not sound and the 
alarm banner does not appear. If the AIS transmission from 
the vessel is lost, a message banner appears.
Dangerous target is lost. A red X indicates that the AIS 
transmission from the vessel is lost, and the chartplotter 
displays a message banner asking whether the vessel should 
continue to be tracked. If you discontinue vessel tracking, the 
lost dangerous target symbol disappears from the chart or the 
3D chart view.
The location of this symbol indicates the closest point of 
approach to a dangerous target, and the numbers near the 
symbol indicate the time to the closest point of approach to 
that target.

NOTE: Vessels being tracked with the Blue Force Tracking 

feature are indicated with a blue-green color regardless of their 

status.

When heading and course over ground information are provided 

by an activated AIS target, the heading of the target appears on 

a chart as a solid line attached to the AIS target symbol. A 

heading line does not appear on a 3D chart view.
The projected course of an activated AIS target appears as a 

dashed line on a chart or a 3D chart view. The length of the 

projected course line is based on the value of the projected 

heading setting. If an activated AIS target is not transmitting 

speed information, or if the vessel is not moving, a projected 

course line does not appear. Changes in the speed, course over 

ground, or rate of turn information transmitted by the vessel can 

impact the calculation of the projected course line.
When course over ground, heading, and rate of turn information 

are provided by an activated AIS target, the projected course of 

the target is calculated based on the course over ground and 

the rate of turn information. The direction in which the target is 

turning, which is also based on the rate of turn information, is 

indicated by the direction of the barb at the end of the heading 

line. The length of the barb does not change.

When course over ground and heading information are provided 

by an activated AIS target, but rate of turn information is not 

provided, the projected course of the target is calculated based 

on the course over ground information.

Before you can show AIS vessels on a chart, you must have an 

external AIS device and active transponder signals from other 

vessels. Mini Automatic Radar Plotting Aid (MARPA) 

functionality works with radar.
You can configure how other vessels appear on a chart or on a 

3D chart view. The display range and MARPA settings 

configured for one chart or one 3D chart view are applied only 

to that chart or to that 3D chart view. The details, projected 

heading, and trails settings configured for one chart or one 3D 

chart view are applied to all charts and to all 3D chart views.

From a chart or a 3D chart view, select Menu > Chart Menu 

> Other Vessels > Display Setup.

Select an option:
• To indicate the distance from your location in which AIS 

vessels appear, select Display Range, and select a 

distance.

• To show MARPA-tagged vessels, select MARPA > 

Show.

• To show details about AIS-activated and MARPA-tagged 

vessels, select Details > Show.

• To set the projected heading time for AIS-activated and 

MARPA-tagged vessels, select Proj. Heading, and enter 

the time.

• To show the tracks of AIS vessels, select the length of the 

track that appears using a trail, select Trails, and select 

the length.

From a chart or a 3D chart view, select an AIS vessel.

Select AIS Vessel > Activate Target.

You can view the AIS signal status, MMSI, GPS speed, GPS 

heading, and other information that is reported about a targeted 

AIS vessel.

From a chart or a 3D chart view, select an AIS vessel.
