In order to do a proper planning for a project, we need to have some initial information about the issue related to that project. For example, to implement a development plan, it is necessary for us to have some basic information about the project area. ARCGIS software (Geographical Information System) having the capability of zoning based on soil properties, combining different maps and extracting special data from this combination and searching for certain information from available maps, can significantly distribute to implementation of such projects. In this study, we are going to zone the soil of Bushehr city based on geotechnical properties. These properties include LL, PI, SPT, C, φ and the type of the soil. The zonings have been done by two IDW and NATURAL methods. The data have been extracted from hundreds of exploratory boreholes that have been excavated at the area of Bushehr city.
