The creation of thematic maps by photointerpretation of aerial photographs of non-flat areas should rely on orthocorrected images. When the application of orthocorrection is not possible (lack of elevation data or suitable software) the question is posed as to which alternative method minimises the effect of relief in the displacement of the category boundaries. The work described here applies a method for assessing the spatial accuracy of linear features in thematic maps to assess the performances, in mountain areas, of two mapping methods which d
