A method is provided for the quantitative determination of surface properties, wherein a spatially resolved image of a surface to be analyzed, which contains a large number of measured values, is recorded. In a first method step, the measured values are analyzed in order to determine those surface areas which have a specific physical property. A result value of this physical property is then determined, wherein this result value is characteristic of the values of the physical property of all those surface areas of the image determined by analyzing the image. In addition to the result value, a further value (B) characteristic of the surface is determined and this characteristic value is displayed together with the result value (I).
