Abstract:

The current cadastral systems in Ethiopia maintain 2D geometric descriptions of parcels linked to administrative boundary records. However this kind of cadastral system is not reflecting the use space above and under the surface of the parcel. In Ethiopia Urban have various autonomous properties at various levels parcels, single family houses and etc, with overlapping property projections in a 2D unit system. In the highly urbanized areas Addis Ababa, there are properties like condominiums, Railway of Ethiopian under or above rural land, which have overlapping projections in a 2D unit system. This system promote us to increasing requirements of the complex intertwine, such as private house, condominium building, commercial buildings. The technique to meet the objective is that make all the cadastre parcels’ elevation registration system in the cadastre works. The elevation values of the cadastre parcel corners is the main data used to model this system. Which means the main difference between 2D and 3D cadastral system is this data (elevation). At first, the 2D cadastre’s polygon points are positioned and obtain the elevation values of these points precisely reflectorless EDM method. Beside this, by using the AutoCAD technologies it will be provided that the 3D model of the cadastre parcels using the original measurement values with graphical data. Starting from modeled ground parcel by using elevation data the above space parcel modeled registered. This paper proposes a transition from the existing 2D cadastral system to a 3D cadastral system; also integrate 3D representations of the physical objects with two dimensional systems in one database. In addition to this the paper introduces the first version of a 3D urban cadastre and land registration system (3DUCLRS Version 1.0). 3DUCLRS models both the legal and physical extent of 3D properties and associated interests. A demonstration of a test system on the proposed data model is also presented. In general this problem solves by making the elevations project of the engineering constructions.
