Abstract
3D cadaster is a tool in a land administration system to digitally manage and represent stratified
rights, restrictions, and responsibilities (legal models) and their corresponding physical models
such as buildings, utilities, on, above or under the ground surface in 3D. In Adama Town the
registration of land holders in the time being cannot expresses the 3D information and the 3D
cadastral data modeling application. Using 2D cadaster data model have no much more importance
to clearly register and manage the property of individuals. Due to unregistered 3D
objects(Building), individual property has no security, illegal settlements inside the town and
around the town increasing time to time, financial institution has no grantee for mortgaging for the
individual properties. The aim of this research is to develop 3D Cadaster Data Modeling in case
study in Adama in order to digitally represent real property ownership rights, restrictions, and
responsibilities (legal models) and their physical counterparts to secure individual property and
control illegal settlements inside the town and around the town. The methodology used to develop
the 3D Cadastral Data Modeling was based on the data-modelling development cycle using Entity
Relationship (E-R) Model techniques/method in this research and the top down approach was also
used for data modeling. The data-modelling development cycle method was, gathering the
requirements of 3D cadaster data (Business Analysis) from the real world, conceptual data
modeling of 3D cadaster, logical data modeling of 3D cadaster and physical data modeling of 3D
cadaster. The software used in this research thesis was, ArcGIS 10.3, Visio 2016, Object oriented
programming language. After the requirement gathered from real world, conceptual, logical and
Physical data model were modeled for the implementation of 3D cadaster in Adama Town
developed different data entry for fully implementation of the 3D cadaster.
