| Abstract | Land-related information (LRI) includes various sources of information in relation to land uses and space-dependent activities compiled by functional agencies and their specialized ad-hoc systems. As no strong guide exists, these information systems rarely describe the same object in the same way. The poor conditions and wide incompatibility of many LRI sources pose a considerable bottleneck to urban planning, a multi disciplinary field that often needs wide-ranging information and depend upon many other sources to provide it. It is the objective of this research to explore a relevant model to address these issues. Focusing on developing cities and Ha Noi City in Viet Nam as the study area, the author examines the LRI conditions, information needs and factors impacting the integration and share ofLRI sources. In Ha Noi City the LRI needs for urban planners to cope with rapid urbanization are enormous. However, LRI sources such as topographic maps, planning documents, socioeconomic statistics and operational data are available at separate city agencies are often old, excessively general, incomplete in contents, and of varying standards. Detailed maps and land information are mostly not available. The LRI improvement is slow due to the lack of funds and coordination. Actual measures such as the use of planning taskforce, ad-hoc appraisal meetings are temporary, time consuming and effective in the operational system. The information programs focus mainly on hardware, not on data and application needs. Agencies proceed spontaneously with various information systems that lead to increasing fragmentation ofLRI sources. The research analyzes and defines an open multi-level integration model (OMIM) as a general framework for integration and share of LRI sources. The model employs three common integration elements: register, coding and scale. The integration structure is open and virtually handled by agency-based systems. Its implementation is progressive depending on the agency capacity and resources. In an application to urban planning in Ha Noi City, the OMIM concept is developed into a tree-like prototype using the national Gaussian coordinates, inheriting coding of administrative boundaries, land uses and street network, and three abstract scales. The integration is designed in a four-stage process as a progressive refined cycle for different agencies. A model prototype is built using data and tools similar to the Ha Noi context. Demonstrative applications of the model are carried out for several cases in the area of Lang Ha and Thanh Cong wards in Ha Noi City. The first case enables analysis of noticeable disappearance of water surfaces, and operation of primary school, which are significant for urban planning. The second case shows that coordination between utilities and socioeconomic factors in integrated planning is possible using the prototype. The third case shows the prototype as a supportive system for analyzing the correlation of dengue incidences with spatial development patterns, such as its close relation with the old housing quarter in highly urbanized Dong Da district. Designed for immediate application, the OMIM needs only a city management role to adopt and guide participating city agencies to use their own resources and information systems for better integration and share of new and existing LRI sources. This solution is institutionally relevant and cost-effective for Ha Noi City and other similar cities to uplift LRI improvement for effective urban planning. |
