Abstract:Land information management can serves many actors involved in land related activities. As an integral part of land administration, it manages parcel-based datasets as the core component. However, the overlap and duplication of effort to gather and produce parcel-based datasets can occur. Therefore evaluating redundancy of parcel-based datasets is needed. The main objective of this research is to evaluate the extent and nature of parcel-based datasets redundancy. Identifying the actors with their roles and the parcel-based data flows are treated as entrance to evaluate the redundancy phenomenon. From the identified actors, the users and producers who related to parcel-based datasets can be determined. The frame of case study is used in conducting this research. Depok City serves as a case study. The literatures concern with the component of land administration, the use and users of land information management, the concept and cause of redundancy, the concept of SNA and the way to address redundancy are reviewed. From literatures, the variation types and the related indicators to evaluate the extent, the cause of redundancy and the role of social networks are developed as a framework. Interview is the only method applied for the primary data collection. The interview questions are based on the developed indicators. Documents related to the policy, regulation and the proposal to address redundancy are examined to amplify the views given by the respondents. The results show who the actors are, the users and the producers of parcel based datasets. From the users it can be known from whom they obtain the data and from the producers it can be known who use their data. The results also reveal that more than one organization creates and manages parcel-based data for different purposes in line with their institutional mandates. The occurrence of the repetition on data creation and maintenance which involve certain processes and tasks to conduct based on certain policies and regulations can be found. The different standards in generating data are applied among producers. The data exchanges among producers also happen. The results also showing the awareness among producers about the redundancy issue. Related to the role of social network, the data is insufficient to derive any conclusions in relation to the indicators that have been developed. According to the redundancy conceptual framework used, redundancy is constituted by repetition and management, repetition of processes and tasks, and management to handle replication and fault handling. The results of the evaluation show that the availability of data which meet to the standards that can be used to achieve defined objectives is a factor which can lead to redundancy. The redundant data on parcel-based datasets is generated through repetition of tasks and activities which related to the data handling. The management to replicate the data is in order to ensure the availability of data that can be used to meet the defined objectives. Keywords: Redundancy, Parcel-based datasets, Evaluation
