Abstract:Key words: cadastral map, map conversion, digital map, map renovation The rapid development of technology, social changes, globalization, and economic growth related to land, cause changes in the cadastral trend (ELayachi and Semlali, 2001). Nowadays, it is not only used for land registration processes or fiscal and legal purposes but more in supporting the management of land and land use, and facilitating sustainable development (FIG, 1995). In order to achieve its purposes, the cadastral system must provide reliable, accessible and advanced information related to land. With regard to this condition, the performance of traditional cadastral systems is no longer compatible and adequate (Kaufmann and Steudler, 2001) to achieve the purpose. They are difficult to adjust to all new developments and to meet all user requirements. The traditional cadastral systems are also hard to provide efficient and cost effective services. As stated in Cadastre 2014 (Kaufmann and Steudler, 2001), automation is recognized as a suitable tool to improve the performance of cadastral systems. The automation processes can be attained through computerization. Through computerization, faster speed on acquiring, storing, retrieving, and disseminating data can be achieved, and it also provides the basis for quality control. The other benefits of computerization are accessibility of wide area network and provide the possibility of data manipulation used in data analyzing and modelling. The existing conditions of cadastral maps in Indonesia are far away of being so called accurate, complete and up-to-date. They were established by BPN using different methods and scales causing the different qualities of cadastral maps. Moreover, as stated by Winoto (2009), the number of land parcels registered and titled is 24.5 million land parcels out of the number of 84.5 million land parcels all over the Indonesian territory (including forest areas). Among the 24.5 million land parcels, 40% of the maps they are still paper based maps and databases (non-digitized) and also still broadly looselyconnected each other. Meanwhile, there is an expectation on building National Spatial Data Infrastructure (NSDI) where cadastral maps as the basis of this system; hence the cadastral maps have to be in digital environment with a uniform structure such as uniform in data quality. In order to have cadastral map data in digital environment, there should be data conversion from analogue to digital format. Basically, there are four methods of data conversion: (1) manual digitizing, (2) scanning (heads-up digitizing and automated vectorization), (3) coordinate geometry (COGO), and (4) conversion of the existing digital. As the aim of this research is to design a conversion strategy of cadastral map data from analogue to digital and also to analyze its implementation to provide an accurate, complete and up-to-date data of cadastral system, hence the investigation of the existing data conversion that can be applied for Indonesia is going to the main concern of this research and the selected method should be minimal loss of data quality, low cost and minimal time. v Map conversion is not only limited to make cadastral map available in digital format but more than that the digital cadastral map has to be accurate, complete, and up-to-date. Due to this there is a need to improving the existing cadastral maps through map renovation. The purpose of map renovation is to improve the quality of cadastral maps either from geometric or semantic specification (Salzmann, Hoekstra et al., 1998) so that they can be used nationwide. Hence a frame work for map renovation as apart of map conversion is going to be built for this research.
