The Development of a Prototype SDI compliant 2D Cadastral Parcels Mode

The National Centre for Statistics & Information (NCSI) is the leading body responsible for the Oman National Spatial Data Infrastructure (ONSDI). In the absence of a national cadaster system for land management, research was undertaken to develop a 2D cadastral parcels model for Oman which is compliant with SDI and in line with the International Standard ISO 19152 Land Administration Domain Model (LADM). The research methodology involved examination of case studies for three regions (the UK and Northern Ireland, Ireland, and Denmark) that have established SDI and used a cadastral theme as a fundamental dataset. Emphasis was placed on the existing cadastral system. The examination of the existing cadastral system in the Ministry of Housing was conducted emphasis was placed on the current 2D cadastral model feature attributes and land registration. The evaluation of ortho-photos focused on coverage/duration, accuracy, resolution and processing procedures applied to produce aerial survey photography and the ortho-photo development procedure. INSPIRE and FGDC standard practices together with the existing cadaster dataset at the Ministry of Housing was used to develop the new model.
