Which of the following must an ECDIS system be able to perform?
AI Explanation
The correct answer is D) All of the above.
An ECDIS (Electronic Chart Display and Information System) system must be able to perform the following functions:
1. Transformation of local datum to WGS-84 datum: ECDIS systems must be able to convert chart data from local or regional datums to the global WGS-84 datum, which is the standard used for GPS and other navigation systems.
2. Conversion of "graphical coordinates" to "display coordinates": ECDIS systems need to be able to translate the geographic coordinates of chart data into the appropriate screen coordinates for display.
3. Calculation of true azimuth and distance between two geographical points: ECDIS systems must be able to calculate the true bearing and distance between any two points on the chart, which is crucial for navigation.
All of these functions are required for an ECDIS system to properly display and utilize electronic chart data, which is why option D) is the correct answer.
