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.

Land

Administration

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.

5



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

Core Model



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.
