1 Tarla Bitkileri Merkez Araştırma Enstitüsü, Ankara - The study area covers, Haymana Research Farm of Central Research Institute for Field Crops and Kenan Evren Research and Practice Farm of Ankara University Faculty of Agriculture. This area is in Ankara city, at 22nd km of Haymana-Gölbaşı province road and it is total 968 hectare. The studies, which were done in project, have two steps. In these steps, the area works were the first one. In the areas by using GPS of the roads, parcels, and pond co-ordinate points were red.

To prepare detailed geological maps, lithological formation borders were determined and to analyse soil structure of working areas, at 42 different points and depths soil samples were taken. After area works, soil, geological, percolation and roads maps prepared and these parameters were linked to each other to make query.

At the end of the project, first existing land use position of area was fixed by determination of parcel areas and crop design. The total area of whole parcels was defined with crop design from past to future. The characteristic features of soil like slope, drainage, erosion, stones etc. were connected with each others and then distribution of CaCO3 , pH, Salt etc. elements in the area were determined. According to type of crop, the suitable area was fixed. In this manner, land use planning could be done.

The digital elevation model of the area prepared and the air photographs which belong to 1980 and 1999 were compared to determine the changes of the pond. Keywords : Land Use Planning, Database, Digital Elevation Model
