Abstract

This paper describes a framework for a visual analysis of lightning data described by 3D coordinates and the precise occurrence time. First lightning cells are detected and tracked. After that we developed a GUI (interactive graphic user interface) in order to enable the visual exploration of movement patterns and other characteristics of lightning cells. In particular we present different visual concepts for the dynamic lightning cells and tracks within a Space–Time-Cube and a 3D view. Furthermore a statistical analysis is presented. The developed GUI which aims to support decision making includes the visual and statistical representation of cell features as centroid, extension, density, size etc., within a specific temporal and spatial range of interest.
