Its objective is to determine through
interbureau action which portion of the
public domain is suitable as a forestland
and which could be released as
agricultural (alienable and disposable)
land. Lands which are found suitable
for agricultural purposes and declared
as such are then slated for distribution
to qualified beneficiaries.
NAMRIA provides inter-agency
technical assistance on the country’s
entitlement for ECS and establishment
of its baseline in accordance with the
provisions of the United Nations
Convention on the Law of the Sea
(UNCLOS), and in fulfilling other
international obligations/requirements
provided for by the International
Hydrographic Organization and the
International Maritime Organization.
NAMRIA is involved in the
delineation of the national maritime
jurisdiction in accordance with the
provisions of the UNCLOS. NAMRIA
is a member of the ECS Technical
Working Group (TWG) which is fully
engaged in the preparation of the
Philippine submission to the UN
Commission on the Limits of the
Continental Shelf. The ECS TWG is
headed by the DENR Secretary under
the supervision of the Commission on
Maritime and Ocean Affairs (CMOA),
Office of the President.

NAMRIA is
responsible for the
surveying and
charting of the
country’s maritime
zones/areas which
are the archipelagic
waters, contiguous
zone, Exclusive
Economic Zone
(EEZ), Extended
Continental Shelf
(ECS),
and
territorial sea. The
agency regularly
c o n d u c t s
hydrographic,
bathymetric, oceanographic, and
geophysical surveys wherein marine
geographic information are presented
in the form of nautical charts,
bathymetric maps, thematic maps, tide
and current tables, and special maritime
publications. These are basic requisites
for safe and efficient maritime travel and
trade, marine environmental
protection, infrastructure engineering,
military defense, and scientific studies
and researches. NAMRIA undertakes
its survey activities utilizing its two
multidisciplinary survey vessels, BRP
HYDROGRAPHER PRESBITERO and
BRP HYDROGRAPHER VENTURA,
which are equipped with modern
hydrographic, oceanographic, and
navigational systems.

Executive
Order (EO) No.
45, s. 1993 (as
amended by EO
280, s. 2000 and
EO 321, s. 2004)
mandates the use
of the Philippine
Reference System
of 1992 (PRS92) as the standard
reference system for all surveying and
mapping activities in the country by CY
2010. NAMRIA is spearheading the
implementation of PRS92 Project in
coordination with the DENR regional
offices, particularly the Lands
Management Bureau, the Forest
Management Services, and the Lands
Management Services. The project aims
to transform old maps and surveys into
PRS92. It also aims to upgrade the
horizontal and vertical control
networks of the country and ensure the
reliability, completeness, and accuracy
of PRS92 as the national geodetic
network. The other key activities of
the project are the upgrading and
densification of geodetic control points,
the conduct of leveling and gravity
surveys, and the installation
a

d
upgrading
of
tide
monitoring
stations.
Land Classification
NAMRIA
produces

topographic
base maps and
thematic
maps at
various
scales in
support
of
the
government’s
development
planning,
environmental
management, and
multihazard
mapping, among o t h e r
programs.
Digital and
cartographically enhanced largescale topographic maps (1:10,000
scale) provide more detailed
information on administrative
boundaries, drainage systems,
existing infrastructure, major
establishments, road networks,
topography, vegetation, and other
economic indicators showing the
present development in the area at
barangay level. Similarly, mediumand small-scale maps (1:50,000 and
1:250,000 scale) are support tools
for applications at municipal and
provincial levels. Administrative
maps indicate political boundaries
of provinces and regions of the
country.

CORE FUNCTIONS
NAMRIA integrates geographic
and resource data to facilitate their
access, analysis, and conversion into
useful information. It develops and
maintains databases and information
systems and networks, packages
information materials, and disseminates
geographic and resource information.
The agency is in the forefront of
developing a national spatial data
infrastructure (NSDI), which is the
integration of technologies, policies, and
people that provide the means through
which government, private and
academic organizations efficiently
produce, manage, and share geographic
or spatial data.
