PIMS Industrial Problem Solving Workshop in August 2018 offered a problem involving 2D phase unwrapping data acquired using distributed acoustic sensing (DAS). This report provides a summary of the work done during the week-long workshop. We begin with a description of the phase unwrapping problem. We consider the DAS dataset on which new methods were employed. We look at the results of the unwrap function found in MATLAB on the data and then provide a full description of two methods developed during the workshop. We then offer a comparison of the results from the two strategies.
