Who maintains the National Database on Surveying Instruments?

• A. Land Management Bureau
• B. Lands Management Service
• C. Denr
• D. National Mapping Authority

Answer: (A)

Surveying instruments are central to reliable land surveys and the administration of land records. The National Database on Surveying Instruments falls under the Land Management Bureau because this bureau oversees land administration, cadastral surveys, and the standards and equipment used in these activities. Maintaining an official inventory of surveying instruments ensures proper accountability, calibration status, and consistent use across DENR surveying operations, which aligns with LMB’s mandate. The other options don’t fit as neatly: the Lands Management Service is a functional unit within the broader land management realm but is not identified as the central holder of the instrument database; the DENR as an entire department is too broad for a specialized instrument database; and the National Mapping Authority (NAMRIA) concentrates on mapping and geospatial data, rather than maintaining a national database of surveying instruments.
