National Mapping and Resource Information Authority (NAMRIA)
Also known as: NAMRIA (official acronym) · Philippine central mapping agency
Definition
The National Mapping and Resource Information Authority (NAMRIA) is the Philippine government’s central mapping agency, attached to the Department of Environment and Natural Resources (DENR). It is responsible for producing and maintaining the country’s topographic base maps, nautical charts, geodetic control networks, and natural resource information, serving as the authoritative source of geographic and spatial data for land and marine administration.

Examples and Analogies
NAMRIA functions like a national surveyor and cartographer combined, analogous to the United States Geological Survey (USGS) or the United Kingdom’s Ordnance Survey. Just as a city engineer needs an accurate base plan before building infrastructure, national agencies rely on NAMRIA’s maps and geodetic reference before planning roads, determining administrative boundaries, or titling land.
Usage Scenarios
NAMRIA data is used in cadastral and land titling programs, delineating municipal waters for coastal local government units, producing nautical charts for mariners navigating Philippine seas, preparing hazard and topographic maps for disaster risk reduction, maintaining the Philippine Reference System of 1992 (PRS92), and standardizing geographic names through its Board on Geographic Names function.
Strategies
The agency pursues digital modernization of its mapping production lines, adoption of satellite remote sensing and LiDAR-derived data, integration of information into a national spatial data infrastructure, and capacity-building partnerships with international mapping organizations to keep Philippine geospatial standards current.
Security and Safety Measures
NAMRIA data is subject to national security protocols: certain high-resolution maps, geodetic information near sensitive installations, and nautical charts are regulated, and the agency coordinates with defense authorities on the release of strategically sensitive geographic information.
Historical Context
NAMRIA was created in 1987 by Executive Order No. 192, which reorganized the DENR. It consolidated the functions of the former Bureau of Coast and Geodetic Survey, the National Cartography Authority, the Land Registration Authority’s mapping units concerned with natural resources, and the Natural Resources Management Center, unifying mapping and resource information work under one agency.
Challenges and Controversies
The agency faces backlogs in cadastral survey coverage, funding constraints for modernizing aerial and satellite data acquisition, and the persistent problem of fake or erroneous maps circulating online, which it counters by asserting its mandate as the official source of authoritative base maps.
