Validating Oil Spill Dispersion Models Against Real-World Observations Using the GeoPandas Library
TimeFriday, 13 November 20205:15pm - 5:35pm EDT
DescriptionThis talk presents the results of a collaboration between the STFC Hartree Centre and Riskaware Ltd, the aim of which was to create a software validation suite to quantify the accuracy of oil spill model predictions against real-world observations of actual oil spills. The validation methodology is based on a specific set of performance metrics, involving the use of satellite imagery and coastal report data. We discuss the key features of the GeoPandas Python library that we used to read and process the geospatial datasets, including the ability to calculate areas of overlap and centroid locations, two quantities that underpin the performance metrics used to assess the model output. We present an example of how we applied our software to an historic case study, and explain how the metrics are helping to aid the clean up operation of real oil spills at sea.
