1. A method comprising:
obtaining measurement data of a substrate;
obtaining a plurality of fingerprint components from historic measurement data comprising values of a parameter measured at a plurality of positions on from previous substrates similar to the substrate;
determining a linear combination of the fingerprint components that fits the measurement data best;
reconstructing, by a hardware computer, a fingerprint of the parameter across the substrate based on the determined linear combination; and
based on the reconstructed fingerprint associated with the substrate information, outputting electronic data for configuration or modification of an industrial process or of a measurement process of substrates subjected to the industrial process.
