The hexagonal grids utilized here provide a standardized method for overlaying multiple hazards each with different spatial representations. Average annual lightning strike frequency (2010-2019) is calculated for each hex grid (representing 0.5 sq. miles,) by dividing total lightning strikes by number of years in record. Data is symbolized using an equal interval classification scale. Spatial analytics derived by the vulnerability mapping and analysis platform at the university of Central Florida – www.vulnerabilitymap.org
