An interactive data interpretation tool is disclosed for enabling the identification of the position of features in a multidimensional data set, the tool comprising means for displaying an image representing a 2-D slice of the data set; and user input means for causing the storage of the position of a feature in the displayed image, characterized in that the 2-D slice can be displayed as part of a projection of a 3-D image, the third dimension of which corresponds to one of the other dimensions of the data set, the tool comprising means operable in response to a predetermined user input operation to cause the co-ordinate of the currently displayed 2-D slice in the third dimension of the 3-D image to be incremented, and the positions in the 3-D image of any features identified in the previously displayed slice to be indicated. The invention finds particular application to the interpretation of seismological data sets. Other applications include oceanographic and medical imaging data sets.
