Core Functions
Geodetic Control Points
Geodetic Reference System Development
Pursuant to Executive Order number 192, NAMRIA is mandated to establish and maintain the Philippine Geodetic Reference System, the primary reference for all surveying and mapping in the country. It is in line with this mandate that the agency is undertaking the modernization of the national geodetic system (NGS) as part of its core initiatives... under its vision of helping to build a geospatially-empowered Philippines by 2020.

The program is aligned with the United Nations General Assembly Resolution A/RES/69/266 of 26 February 2015, that urges the adoption of, and calls for the active participation of member states, in the definition of a global geodetic reference frame for sustainable development. The modernization program will upgrade the existing Philippine Reference System of 1992, unify the national vertical datum, and strengthen core competencies on geodesy of the NGS stakeholders.

Topographic Base Mapping
Topographic Mapping
NAMRIA produces updated topographic base maps and derivative maps at various scales, in paper form or digital data, for use by the national government agencies, local government units, the academe, the scientific community, and the private sector. These are used as basic tools and common reference in most aspects of governance such as development planning; ...disaster-risk reduction and management, and delivery of government services.

Topographic maps are also used by the private sector in investment planning and exploration, by the academic and science communities in research and development activities, and by the general public. They are regularly updated using the latest aerial photographs, satellite imageries, and field surveys. Small and medium-scale topographic maps (1:250,000 scale and 1:50,000 scale) generally cover large areas. Large-scale topographic maps (e.g., at 1:10,000 scale or larger) generally cover smaller areas but show more detail. NAMRIA likewise produces updated administrative maps in the form of provincial and regional maps.

Nautical Chart
Hydrography, Physical Oceanography and Nautical Charting
NAMRIA conducts hydrographic and physical oceanographic surveys and produces nautical charts (berthing, harbor, approach, coastal, general sailing and overview charts), predicted tide and current tables, coast pilot book, list of lights, notices to mariners and other nautical publications depicting the country's maritime jurisdictions. The surveys and charts ensure safety in maritime ... navigation and provide basic information for the management of the maritime space and resources, as well as base data for climate change studies. The charts and hydrographic data are important in complying with the provisions of the United Nations Convention on the Law of the Sea relative to the country's maritime entitlements. Likewise, the nautical publications are required under the Safety of Life at Sea Convention.

NAMRIA is the national hydrographic office and the focal point for the International Hydrographic Organization and East Asia Hydrographic Commission. NAMRIA undertakes survey activities utilizing its two multidisciplinary survey vessels, BRP HYDROGRAPHER PRESBITERO and BRP HYDROGRAPHER VENTURA. The agency also has two 23.55-meter catamaran hydrographic survey vessels, BRP HYDROGRAPHER ANDRES HIZON and BRP HYDROGRAPHER CAYETANO PALMA for use in the expansion of the agency's hydrographic and oceanographic survey capabilities.

To date, NAMRIA operates and maintains 47 primary tide stations in the country for the continuous monitoring and recording of sea level. Twenty-four of the tide stations are equipped with telemetry system for near-real time transmission of tide data to the NAMRIA office in Manila. Another six tide stations in Manila; Legazpi, Albay; Subic, Zambales; Currimao, Ilocos Norte; Lubang Island, Occidental Mindoro; and Davao City are also linked to the Intergovernmental Oceanographic Commission's Sea-Level Station Monitoring Facility from which users can download in near real-time via the Internet.

NAMRIA also serves as the National Oceanographic Data Center and operates the Muntinlupa Magnetic Observatory which facilitates local and international exchange of oceanographic and magnetic data.
