Which map type uses a spheroidal quadrangle of one minute of latitude and one minute of longitude, drawn in the Philippine Plane Coordinate System at a 1:4000 scale on stable drafting material of approximately 54 by 54 centimeters?

• A. Projection Maps
• B. Municipal Base Maps
• C. Provincial Base Maps
• D. Cadastral Map

Answer: (D)

In cadastral work, the key idea is how land parcels are precisely mapped for legal and ownership purposes using a standardized grid. A spheroidal quadrangle of one minute of latitude by one minute of longitude is the tiniest standard map sheet in the Philippine Plane Coordinate System, designed to capture parcel boundaries with high precision. The 1:4000 scale provides enough detail to delineate individual boundaries clearly, while the ~54 by 54 centimeter stable drafting material describes the physical size and durable medium used for these cadastral sheets. This specific combination—one-minute by one-minute quadrangles in the Philippine Plane Coordinate System at a fine scale on sturdy drafting stock—is characteristic of cadastral maps whose primary purpose is showing property parcels and rights. Other map types serve different functions and typically don’t use this exact sheet size, scale, and coordinate framework for parcel delineation.
