Abstract

Methods and systems are described for generating assessment maps. A method includes receiving a first vector map comprising a first set of vectors each indicating a distortion of a particular location on a substrate and generating a second vector map indicating a change in direction of a magnitude of the distortion of the particular location on the substrate. The method further includes generating a third vector map comprising vectors reflecting reduced noise in distortions across the plurality of locations on the substrate and generating a fourth vector map projecting a direction component of each vector component in the third set of vectors to a radial direction. The method further includes generating a fifth vector map by grouping the vectors of the fourth set of vectors and determining a magnitude associated with each group of vectors.
