Abstract

Abstract. Recently in our country, the construction of buildings become more complex and it seems that strata objects database becomes more important in registering the real world as people now own and use multilevel of spaces. Furthermore, strata title was increasingly important and need to be well-managed. LADM is a standard model for land administration and it allows integrated 2D and 3D representation of spatial units. LADM also known as ISO 19152. The aim of this paper is to develop a strata objects database using LADM. This paper discusses the current 2D geospatial database and needs for 3D geospatial database in future. This paper also attempts to develop a strata objects database using a standard data model (LADM) and to analyze the developed strata objects database using LADM data model. The current cadastre system in Malaysia includes the strata title is discussed in this paper. The problems in the 2D geospatial database were listed and the needs for 3D geospatial database in future also is discussed. The processes to design a strata objects database are conceptual, logical and physical database design. The strata objects database will allow us to find the information on both non-spatial and spatial strata title information thus shows the location of the strata unit. This development of strata objects database may help to handle the strata title and information.

Highlights

  • In developing a place to store all the information of strata, strata objects database seems could give a new approach and a new direction of strata title

  • The proposed draft country profile based on the LADM provides a conceptual model for 2D and 3D cadastral situations for the relevant land administration agencies in Malaysia

  • This paper is organized as follows: Section 2 describes the previous works related with LADM and the current cadastre system in Malaysia includes the strata title

Summary

INTRODUCTION

In developing a place to store all the information of strata, strata objects database seems could give a new approach and a new direction of strata title. The needs for the strata objects database had been clearly mentioned and discussed in the 3rd International Federation of Surveyors (FIG) Workshop which held in Shenzhen, China in October 2012. This idea can provide exact 3D objects or properties with their boundaries regarding strata title of features and assist the management including the RRRs (right, restriction, responsibility) of strata title. The proposed draft country profile based on the LADM provides a conceptual model for 2D and 3D cadastral situations for the relevant land administration agencies in Malaysia. This paper is organized as follows: Section 2 describes the previous works related with LADM and the current cadastre system in Malaysia includes the strata title.
