Dramatic increase in the
establishment and
improvement of land
administration systems.
Tools are required to facilitate
the implementation of a proper
land policy. This is where land
administration (LA) and land
administration system (LAS)
enter.
Land Administration (LA)
refers to the processes of
recording and disseminating
information about theownership, value and use of
land and its associated
resources. (UNECE, 1996)
2010)
Introduction
The retrieving, updating
and tracking of land
related data are still
paper-based; this is
often true for LGU’s.
Several attempts to
improve LAS were
undertaken primarily to
provide formal recognition
of rights in land.
Government needs information
to govern. An efficient solution
to achieving this is a software
application built on top of a data
model.

General Specific Poor mechanism of data
exchange and sharing and
lack of equipment for records
management.
Poor linkages between
different stakeholders in landadministration.
LA processes is not easily
accessible and is complex.
Inability of the current LA to
address user requirements
efficiently and effectively.

• What is the status of LA in the
Philippines?
• What are the current
initiatives taken by the
government to upgrade its
LAS?
• What is the scope of the
model?
• What LADM classes are
included and what are notincluded?
• What are the benefits of the
development of the model?

Research Objective - General
Development of a model based
on the ISO 19152 Standards –
the Land Administration Domain
Model (LADM) Standards,
representing the currentsituation of the LA of the
Philippines focusing on the
perspective of the Local
Government Unit (LGU)
describing its relationship withthe two main agencies involved
in land administration, LRA and
DENR.

One
• Study the current situation of LA in the Philippines.
Identify LA-related problems and its possible solutions.
Two
• Identify, from documents gathered, classes adopted,modified and added based on LADM.
Three
• Provide a Dictionary of Terms used within the model.
Four
• Provide the LGU a model as an initial reference to attain apaperless-based and more efficient land administration.
Five
• Define how the model displays the relationship betweenthe LGU with LRA and DENR in terms of data sharing.
Research Objectives - Specific

Significance of the Study
The data model is the core, data to include
and how to structure this.
The study will provide connections of
different entities related to land
administration (relationships between
classes in packages).
The model will establish relationships on
how the LGU with interact with the LRA and
DENR for an efficient data management.
The results will satisfy the need for a
coordinated land information system for an
efficient data management.
The research will provide a foundation on
building LGU’s own software application

Scope and Limitations of the Research
The research only takes into account three (3) of those agencies namely the DENR, LRA and LGU.
The research is limited to construction of a model and does not include its implementation on aplatform.
The model will only take into consideration 2Dcadastre.
LGU indicated here refers to Makati LocalAssessor’s Office. LGU does not necessarilyencompass all of the LGU’s throughout the
country.
The construction of the model is confined andbased on the documents gathered and interviews done.

One of the most complex systemsin Asia and is currently plagued
with institutional defects,
inconsistencies and corruption.
Generally neither efficient noreffective.
19 agencies involved LA and the
two principal agencies are DENR
and LRA.
There are two legal processes in
gaining title to land—
administrative and judicial

• The LADM is a conceptual schema derived from CCDM.
• LADM is a simplification and standardization of CCDM.
Core Cadastral Domain Model (CCDM) and Land
Administration Domain Model (LADM)
Organised in packages:Party Package,
Administrative Package and
Spatial Unit Package.
The purpose of the LADM is
not to replace existingsystems, but rather to
provide a formal language
for describing them, so that
their similarities and
differences can be better
understood.
The heart of the model isbased on the three classes:
RegisterObject; RRR, and
Person.
Goal is to avoid re-inventing
and re-implementing thesame functionality but
provide a extensible basis
for efficient and effective
cadastral system
development enable
involved parties tocommunicate based on the
shared ontology.

Validation Scheme
ISO 19105 - Geographic Information Conformance and Testing
Specifies the framework, concepts and methodology for testing and criteria to be
achieved to claim conformance to the family of ISO geographic information
standards.Abstract Test Suite (ATS)This test suite specifies the
requirements that the
implementation under test has tomeet in order to be conformant to
an International Standard.
Conformity element: conformant,
not conformant, not evaluated .
Conformance Levels: 1, 2, 3
User RequirementsThe user requirements will become
the basis if the model will fit their
needs.
