A Spatial Decision Support System design for land reallocation: A case study in Turkey

• Land consolidation (LC) is a tool for supporting rural development.
• One of the most important steps of LC projects is land reallocation studies.
• Problems after reallocation process are main reasons for objections.
• In this study a Spatial Decision Support System software is developed for reallocation stage.

Reallocation of regular size parcels is accepted as the core of land consolidation. For fast and efficient progress in projects, usage of computer technology has been essential.In this case study, a Spatial Decision Support System (SDSS)-based land reallocation model was developed to provide reallocating newly created regular size parcels to landowners in land consolidation projects. Reallocation results of the SDSS-based land reallocation model and conventional land reallocation models are compared. Surveys were conducted with the landowners in order to obtain their opinions of the land reallocation results. The purpose of the survey study was to determine which of the two land reallocation models they preferred. 66.1% (39 people) of the interviewed landowners stated that they were pleased with their land reallocation on the basis of the conventional land reallocation model. This compares with 89.9% (53 people) of the landowners who expressed that they were pleased with the outcome of the SDSS-based model. According to the results, the SDSS-based land reallocation model was more preferred by landowners.
