Challenges of integrating cadastral map and urban data infrastructure in Iran

Abstract

Producing rich cadastral maps of megacities is time-consuming and imposes exorbitant costs on the concerned organizations. Due to rapid urban expansion and development, keeping maps up-to-date is a significant challenge for spatially enabled government and land administration affairs. Therefore, in order to keep urban cadastral maps up-to-date and enrich their content geometrically and thematically, a number of issues should be resolved. In this research, challenges in integrating and enriching the urban and cadastral map data of different organizations in some parts of a District of the mega city of Tehran, the capital of Iran, have been investigated. Some of the important challenges are the heterogeneous methods of map production, inconsistency in the employed maps currency, existence of a variety of map scales produced in different urban organizations, lack of coordination and cooperation in map data formats, production methods, and standardization. This paper has attempted to overcome these challenges.
