Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

ECDIS is a marine navigation system that integrates three key components: digital nautical charts (route maps), GPS positioning data, and directional/heading data from the ship's helm. Options A and B each miss one of these three essential components.

Which of the following describes the model used by the Geodetic Extender?

  1. Flat earth

  2. E-D square

  3. Trapezoidal

  4. Round Earth
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The DB2 Geodetic Extender uses a Round Earth model (spherical model) for spatial calculations rather than flat-earth approximations. This is essential for accurate geographic and geodetic computations over long distances where Earth's curvature matters. Geodetic coordinate systems account for the Earth's spherical shape, unlike planar projections that distort distance and area measurements.

Multiple choice

The observations from a closed loop traverse around an obstacle are as follows

Segment Observation from station Length (m) Azimuth (clockwise from magnetic north)
PQ P Missing 33.7500o
QR Q 300.000 86.3847o
RS R 354.524 169.3819o
ST S 450.000 243.9003o
TP T 268.000 317.5000o

What is the value of the missing measurement (rounded off to the nearest 10 mm)?

  1. 396.86 m

  2. 396.79 m

  3. 396.05 m

  4. 396.94 m
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

For a closed traverse, the sum of latitudes and departures must be zero. By calculating the latitude (L = length * cos(azimuth)) and departure (D = length * sin(azimuth)) for each segment, one can solve for the missing length of PQ by setting the sum of all latitudes and departures to zero.

Multiple choice

What is the primary objective of data localization laws?

  1. To require companies to store data within a specific geographic location

  2. To protect personal data from unauthorized access

  3. To promote economic growth in developing countries

  4. To prevent cybercrime
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Data localization laws require companies to store data within a specific geographic location, often the country where the data was collected, in order to protect data sovereignty and comply with local regulations.

Multiple choice
