New and redesigned settlements are needed but appropriate plots of land are not usually available. A more efficient distribution of land is required. Land readjustment is one of the approach to deal with these urbanisation problems. This paper briefly explains the land readjustment process and its potential use in urban development, then, illustrates the development of a GIS-based land readjustment model for a better land management in rural-to-urban land-use change procedures. INTRODUCTION Since land is a limited natural resource for human activities, it require effective management systems. Especially, rapid urbanisation requires serviceable land for public and private needs. Traditionally, not only in Europe but also in the other parts of the world, continued subdivision of land over the years has resulted in the fragmenting of land parcels into incredibly small units. Since land is basic and tenaciously held, remedies to the fragmenting of land parcels must be deliberate, carefully planned, and executed both by government and private bodies. However, land readjustment is one of the urban planning process that can provide with these requirements. Land readjustment (LR) may be defined as a land management tool which assists to orderly urban development by the contribution of landowners. The main objective of LR is to convert irregulary developed land parcels into the suitable forms according to town planning requirements. It has great advantages in solving the land-use problems in urban areas but the current implementations are still faced with some limitations. These included technical limitations in handling the wealth of data, economical limitations in compensation for acquiring land, and social limitations in minimising the inconvenience and conceived injustices. Therefore, the re-examination of these issues are essential. Geographical information systems (GIS) have been widely used in many urban planning applications (Maguire, 1991). To maximise the benefits from LR a new approach has been developed using GIS. In this approach, many substantial criteria which may affect a land parcel value are evaluated and their contribution spatially analysed for the LR process. This paper, first, gives a brief introduction about LR, then explains the development of a GIS-based land readjustment model for urban development.
