Which map type is prepared and kept up to date for each city, municipality, or municipal district, covering a spheroidal quadrangle of 15 minutes of arc in latitude and 10 minutes of arc in longitude, and drawn in the Philippine Plane Coordinate System at a scale of 1:60,000?

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

Answer: (A)

Municipal base maps are prepared and kept up to date for each city, municipality, or municipal district. They cover a standardized spheroidal quadrangle of 15 minutes of latitude by 10 minutes of longitude and are drawn in the Philippine Plane Coordinate System at a scale of 1:60,000. This combination—local coverage, regular updates, a fixed 15′×10′ quadrangle, and the country-specific coordinate system—makes them the reference base map for planning and mapping at the municipal level. Cadastral maps focus on parcel boundaries, provincial base maps cover larger areas than a single municipality, and regional base maps span even broader regions, so they don’t match the描述 exactly.
