| Summary: | In Malaysia, the cadastre system is controlled by two main ag
encies, namely, Department of
Surveying and Mapping Malaysia
(DSMM) and Land Offices (L.O). The DSMM is
responsible for the cadastral spatial information i.e. land parcel boundaries. The
mission is to enhance quality in surveying and mapping services
along with managing the geospatial data. On the other hand, Lan
d
Office is responsible for the cadas
tral attribute information i.e. legal rights that attached to the cadastral objects or plots
. The current
system only involves with 2D maps and no effo
rt towards 3D registration yet. This pape
r discusses 3D cadastre in the aspect of
property registration i.e. complex building
and overlapping properties on di
fferent land use. We also
discuss the interoperabil
ity of
the two systems between the two different ag
encies. This 3D cadastre re
gistration will serve as a first attempt to develop a mo
re
complete Integrated Malaysian 3D Cadastre System. A complex system needs a clear a
nd concise method to show the representation
of data, and here we utilize Unified Modeli
ng Language (UML) for the data modeling task
as it has been considered better techni
que
for such real world data modeling like cadastre data compared
to the traditional entity relationship approach. Besides 3D regis
tration,
the paper also discusses 3D mode
ling, 3D geo databasing and 3D vi
sualization. Malaysia could emba
rk on this 3D cadastre system
relatively straight forward since it has good 2D cadastre framework.
From the research and discussion it can be realized that t
he
hybrid approach certainly would be a good to
start with. This approach means preservation of 2D cadastre and the integration of the
registration of the situation in 3D by registering 3D situations integrated and being
part of the 2D cadastral geographical dat
a set.
Nevertheless it is reasonable to believe that there are some
irregularities and different inform
ation as both systems operates
separately. This situation shall trigger a good basis why there is
a need for the integration. The challenge is to transform th
e proposed
model into computer means i.e. logical model. The validation of logical model will be then encoded in the spatial database. Spa
tial
DBMS is the foundation for both GIS (presenta
tion, analysis) and CAD (creating models). It offers spatial data type in its data
model
structure and also in the query language and it can interact with
the spatial DBMS. This paper elaborates on an integration of
Oracle
Spatial and Autodesk Map 3D for an integrated 3D Cadastre. The 3D Cadastre database
development especially
on the aspect of 3D
objects registration form major contributi
ons of the paper towards the developm
ent of an integrated 3D Cadastre.
