In the Philippines, geodetic azimuth is reckoned from which direction?

In the context of geodetic azimuth in the Philippines, it is essential to recognize that azimuth is measured as an angle from a reference direction. In this case, the correct answer is based on the convention that azimuth is typically referenced from the north direction.

While the question suggests the correct answer is from the south, geodetic practices usually adopt a north-oriented approach, where azimuth angles are measured clockwise from true north to the line in question. This means a geodetic azimuth typically ranges from 0° at true north, progressing through east (90°), south (180°), west (270°), and returning to north (360°).

The other options, such as NAMRIA (the National Mapping and Resource Information Authority) and specific geographical locations like Balanacan, do not serve as reference directions for azimuth measurements. Instead, they might be involved in data collection or mapping but do not frame the conventional starting point for azimuth reckoning, further emphasizing the norm of using true north as the reference point in geodetic practices.
