Abstract

The Title Deeds and Properties Registration Organization (ITDPRO) in Iran was established in the early 1940s and Cadastral Organization in Iran was established 2 decades ago. All ownership deeds of the country are issued in a traditional textual form, and in this description, there is no direct mention of the coordinates indicating the corners of the land, nor is there a map attached. The result is that it is difficult to find the location of parcels of land which is causing many claims and disputes related to the real estate. In other words, the management of land and property in Iran is currently costing a lot of time and effort.
In addition to that, there is an insufficient number of staff to deal with the problems arising from this situation. The ITDPRO is managed in a traditional way, whereby experts of the ITDPRO are relying on traditional technologies. In contrast, the Cadastral Organization of the country is utilizing modernized technology and young specialists in the field of surveying, geodesy, GIS, and Computer Engineering, who were assigned to reform and reorganize the present situation of properties of the country. This duality is resulting in disagreement on the concepts used among ITDPRO and the Cadastral Organization. The main factors of disagreement of concepts and semantics are differences between advanced technology and old techniques in measuring the parcels and defining the boundary of parcels. A parcel which is placed near a river is defined in many types; connected, limited, or adjacent to the river. The concepts in the past and present can be linked and compatible using ontology. Ontology language helps to match both old techniques and advanced technology in ITDPRO and Cadastral Organization.
This disagreement and promotion of common ontologies could potentially be solved through appropriate distance learning, based on internet c.q. e-services. This article derives such services, based on a data model that deals with heterogeneous and multi source datasets. This was developed through a series of steps. With this model and software employees and experts of ITDPRO may use current Cadastral digital maps at each Cadastral department in each province. Local organizations may thus learn using Internet network in the center of the provinces and will send copies of their findings to the State Cadastral Center. This method allows getting the experts of ITDPRO as target groups to incorporate the modern technology gradually and to cooperate with the Cadastral Organization. Early pilots with the software package are showing that it encourages the experts of ITDPRO to absorb the advanced technology.
