METHOD OF DETERMINING AN EDGE OF AN ANOMALY, METHOD OF DETERMINING INTERACTION, METHOD OF ALIGNING, COMPUTER PROGRAM PRODUCT, AND DATA CARRIER. Abstract Method of determining an edge of a first anomaly in a wall of a pipeline from a first set of data elements representing measurements of the wall of the pipeline. An element of the first set comprises a first coordinate, a second coordinate, and a parameter being indicative for the presence and/or severity of the first anomaly a position along the wall indicated by the first and second coordinate. The method comprises determining a data element that is associated with a maximum in the severity of the first anomaly; evaluating a value of the parameter by comparing with a predetermined threshold; determining an initial edge data element for which the parameter has reached the threshold; determining a next edge data element; determining further edge data elements; and determining the edge of the first anomaly by combining the first and second coordinates of the determined edge data elements.
