The development of appropriate land-use decisions in the sustainable management of rural and urban areas has great importance. This is particularly the case for central developers (Ministry, Municipality, Special Administration and so on) in the development of land use decisions. As a matter of fact, one of the duties placed in front of our country Turkey during the EU membership process is the preparation of the main spatial data infrastructures on the basis of each basin to manage river basins. In this process, first of all the following procedures should be done to determine watershed based land use within administrative borders. Protected areas, wetlands, forests, rangeland and plateau areas, agricultural protected areas, water collection lines, creek deposits, geologically objectionable areas, built-up areas, landslide susceptible areas should be digitally created in the ITRF system together with property information and ownership data. The use of this data will greatly facilitate the determination of decision-makers, appropriate land management and practices. It is known that basin based spatial data infrastructures have not yet been established in Turkey at this point. It has been found that environmental planning has been established without these data and based on these plans, so incorrect land use decisions have been developed. With this study, spatial data structures for river basins, which are obliged to prepare especially in EU membership process, have been created with the help of GIS technologies. In this process, proposals have been developed for resolving the problems faced by technical, institutional and legal aspects.
