3D cadaster problems are getting attention and studied increasingly. However, correct concepts have not been established for three dimensional land uses and different rights problems around them. This is primarily due to the lack of proper methods for implementation and operation of 3D cadaster. 3D cadaster requiring far more huge data than 2D should be built in DBMS and need appropriate methods and processes for this. This study propose a method to model 3D cadaster using DBMS. First, it analyse and visualize possible problems around divided superficies in 3D spaces. Based on this, it illustrates UML models and shows an O-R mapping process to implement them using a RDBMS.

In the modern society, as the city grows and constructive technology gradually develops, land usage has been sophisticated and three-dimensionalized. Consequently, issues such as property ownership and legal claim over ground and underground space have been triggered, which disclose the problems of using two-dimensional cadastral management system. Numerous researches on building three-dimensional cadastral are ongoing such as defining the right relationship of land space and providing the registration and management scheme so as to solve the imminent matter. It is the chief aim of this study to increase efficiency by analyzing the vocational practices through adding on necessary sections and properties for current registration to original research work. If three-dimensional cadastral management system is once constructed, highly qualified services for citizens will be available by providing accurate land related information swiftly, which can result in inevitable improvement of efficiency at work. Hence, this thesis will suggest the internationally suitable feature model development method in terms of standardization by probing into the factual profession to derive each attributes and properties that are related to three-dimensional cadastral and affix them to the classified item requisites of initial research studies.
