The discontinuity and roughness properties of the rocks can be used to obtain information on surface characterization. In this study, it was investigated whether the discontinuity and roughness properties of the rock structure are related to the temperature of the surface. Selected object which is located at Istanbul Technical University Ayazaga Campus has approximately dimensions of 3 m x 1 m. The discontinuity regions on the object and the areas which are rougher than their surroundings are clearly identifiable by visual interpretation. 3D model of rock surface was produced by integrating photographs and 12 control points which were homogeneously distributed on the object in order to reflect the surface realistically. The temperature of the control points marked on the surface were measured by using an infrared thermometer with non-contact measuring capability. These values were used as the basic data to show the temperature distribution over the entire surface. Temperature distribution map with 6 classes representing the temperature range was produced by using IDW interpolation method in a commercial GIS software. The temperature distribution map was overlapped on the 3D object model produced by means of RGB photographs for comparison with the 3D model produced by the thermal images of the same surface. The temperature distribution in the discontinuity regions that can be clearly seen as rough was examined and obtained results proved that there is a strong relationship between roughness and temperature of the rock surfaces.
