In Nigeria, the spatial requirements of cadastral map for the purposes of land registration are based on 2D planimetric boundary coordinates without consideration for the elevation component of geometric space. Whereas, recent development in technology and practises in many countries requires the inclusion of elevation component into the cadastre. The specific objectives of this study are to determine elevation values for existing 2D cadastre of the study area from different data sources and to analyze those elevation values using statistical means.

The purpose of this paper is to examine the existing real property valuation practice in case of expropriation in Ethiopia and to propose potential bases and approaches compatible to the Ethiopian real property system based on desk review research in which existing literature are the main source.
