As provided for in the Department of Environment and Natural Resources (DENR) Administrative Order No. 31, series of 1988, which prescribed the guidelines implementing Section 22 (a) of Executive Order 192, NAMRIA is mandated to provide the public with mapmaking services and to act as the central mapping agency, depository, and distribution facility for natural resources data in the form of maps, charts, texts, and statistics.
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.  A modern NGS is anchored on a more robust, accurate, and globally consistent reference frame that takes into consideration the complex geodynamic behavior of the Philippine archipelago, and makes full use of modern positioning technologies, such as the global navigation satellite system, for improved positioning, geographic information interoperability, and international surveying and mapping cooperation.


Topographic Base Mapping

Topographic Base 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.  They 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.


Land Classification Mapping

Environment and Natural Resource Mapping

NAMRIAs conducts nationwide environment and natural resource assessment and mapping of various thematic geospatial information such as land cover, coastal resources, low-lying areas vulnerable to sea-level rise, tenurial instruments, and upland/forestland population, among others.  These fundamental datasets serve as vital inputs in policy formulation, physical and developmental planning, provision of social services, disaster-risk reduction and management, and climate change mitigation and adaptation studies at various levels.  In addition, the agency continues to provide information on classification of lands of the public domain as well as technical assistance to the DENR on the delineation of forestland boundaries to support legislation by Congress of the final limits of forestlands and national parks.


Benham Rise

Maritime Zones and Boundaries Mapping

NAMRIA is responsible for the survey and mapping of the country’s terrestrial and maritime territories.  It delineates the different maritime zones of the archipelago including the Exclusive Economic Zone and continental shelves.  It spearheaded the successful submission to the United Nations Commission on the Limits of the Continental Shelf the Philippine extended continental shelf in the Benham Rise Region.  It also provides technical support to various government agencies on matters pertaining to maritime boundary delimitation and Law of the Sea issues, as well as to the local government units in the delineation and delimitation of the 15-kilometer municipal water boundaries.


Philippine Geoportal Project

Geospatial Information Management and Services

NAMRIA's geospatial information management and services include information system strategic planning; geospatial databasing; information and web system development; information and communications technology resource and network management; geographic information systems (GIS) project collaboration and technical assistance; GIS trainings; packaging of geospatial information knowledge products and services; stakeholder relations and partnership development; information, education, and communication; and customer services.  NAMRIA also plays active roles and even acts as lead in various international working groups, fora, conferences, symposiums, and other activities in the area of geospatial information management and services relevant to disaster risk reduction and management and climate change adaptation.  NAMRIA leads in the implementation of a national spatial data infrastructure (NSDI), which is designed to provide a mechanism for sharing of and access to geospatial information produced and maintained by the various stakeholders and custodians across the country.  A major output of the NSDI is the Philippine Geoportal.  This application system, managed by NAMRIA, serves as a platform for online and open sharing of geospatial information.

The governance and policy direction of NAMRIA is provided by a five-member Board of Governors, and an Administrator who is assisted by two (2) Deputy Administrators.

There are four (4) core or technical branches, and one (1) Support Services Branch, with four (4) divisions each. (View Organizational Chart)

Mapping and Geodesy Branch

As the sole mapping agency of the government, NAMRIA through its Mapping and Geodesy Branch (MGB) produces, maintains, and updates base maps that will serve as basic inputs in various development activities of the government, the academic and scientific community, and the private sector.

Another function is to establish and maintain a national geodetic control network to serve as common reference for all surveying and mapping activities in the country.

Hydrography Branch

The functions of the Hydrography Branch (HB) is to acquire and analyze hydrographic and oceanographic data used for promoting navigational safety and oceanographic research. Outputs are nautical charts, navigational warnings, tide and current predictions.

The Hydrography Branch also actively participates to the International Hydrographic Organization (IHO), and its regional office, the East Asia Hydrographic Commission, which aims to ensure that all the world's seas, oceans and navigable waters are surveyed and charted according to internationally-accepted standards.

Resource Data Analysis Branch

The Resource Data Analysis Branch (RDAB) is mandated to conduct land cover assessment/evaluation and land classification. Its functions are:

(1) to provide remote sensing services and vital data on the environment, land cover, forestry, agriculture, water resources, and coastal zone, among others; and

(2) to conduct researches on remote sensing and GIS applications.

Geospatial Information System Management Branch

Geospatial Information System Management Branch (GISMB) works toward the sharing, transfer, exchange, packaging, and dissemination of environment and natural resources data. It develops and maintains information systems and ENR databases for use not only within NAMRIA but also by outside clients.

It also serves as the marketing arm of the agency for all its products and services.

The NAMRIA Map Sales Office or MSO sells maps, nautical charts, and publications produced by the agency. The maps that are available are topographic maps in various map scales and other thematic maps like planimetric and administrative (national, regional, and provincial) maps.

To this date, there are 16 map sales offices located nationwide aside from the ones located at our main offices in Taguig and Binondo. They are usually located or housed in the regional offices of the Department of Environment and Natural Resources (DENR).

Museum of Surveying & Mapping :

The NAMRIA museum is the only museum that traces the history of Philippine surveying and mapping from 1900 to present. It exhibits the 20th Century collections of old survey instruments and equipment used in surveying the Philippine archipelago. The instruments and equipment were used by the United States Coast and Geodetic Survey (USCGS) and later by the Bureau of Coast and Geodetic Surveys (BCGS).

The museum showcases three features. First, the Timeline narrates the history of surveying and mapping in the Philippines, including piece of the country's geodetic datum origin. Second, the Equipment Collection that features old surveying and mapping equipment, the centerpieces of which are the tide-predicting machine and multiplex projector optical system. And third, the Map Gallery displays maps of various kinds-from early Spanish maps of the Philippines to the first NAMRIA-produced analog and digital topographic maps, nautical charts, orthophoto maps, and land classification maps.



   

The museum is open Mondays to Fridays from 9:00 a.m. to 4:00 p.m., except on public holidays. Admission is free.

For inquiries, information, or booking, please call (+63-2) 810-4831 local 401 or e-mail us.
