Which statement about the World Polyconic Grid is true?

• A. It is the predecessor to UTM in the Philippines
• B. It is the current standard in the Philippines
• C. It is a global system used for sea navigation
• D. It is identical to the UTM system

Answer: (A)

The World Polyconic Grid represents an older global mapping framework that uses a polyconic projection to lay out a grid for surveying and map reference. In the Philippines, this grid served as the earlier reference system before adopting a more modern, zone-based approach. When the Universal Transverse Mercator system was introduced, it replaced the polyconic grid for national mapping because UTM offers a consistent, worldwide standard with clearly defined zones, which makes large-area mapping and coordinate reporting more uniform. So this statement is true because it correctly describes the World Polyconic Grid as the predecessor to UTM in the Philippines. It’s not the current standard, it’s not a global system used for sea navigation, and it’s not identical to UTM—the latter is a zone-based transverse Mercator system, while the former is a different projection.
