The present projection used in cadastral project and topographic projects in the Philippines is :

• A. Transverse Mercator Projection
• B. Mercator Projection
• C. Polyconic Projection
• D. Lambert Conformal Projection

Answer: (A)

The Transverse Mercator projection is used because it provides a conformal, zone-based grid that minimizes distortion along each central meridian, making it ideal for precise cadastral and topographic work. In cadastral surveys you need accurate measurements of parcel boundaries, bearings, and areas, and a projection that preserves local shapes and keeps scale consistent within each zone supports that reliability. The Philippines often uses a grid system built from these TM zones (similar to UTM), which suits the country's narrow north-south extent and the need for uniform, map-ready coordinates. Other projections either distort areas or scales more noticeably in this region (Mercator distorts distant areas, Lambert Conformal Conic is better for different extents, and Polyconic is older and less aligned with modern national mapping practices), so Transverse Mercator remains the standard choice.
