ANALYSIS AND 3D VISUALISATION OF WILDFIRES USING EARTH OBSERVATION DATA

Master's thesis

Analysis and 3D Visualization of wildfires using Earth Observation Data.

Abstract:

This thesis aims to evaluate the possibility of integrating remote-sensing data into advanced 3D visualization and animation. The primary objective is to develop and document a comprehensive workflow for the modeling and rendering of wildfire parameters derived from remote sensing within a 3D environment, with the 2023 Maui Island Fires serving as a case study. The research encompasses an evaluation of the applicability of satellite-derived active fire points and Aerosol Optical Depth (AOD) data, which represent smoke plumes, in the retrospective modeling of wildfire spread. In addition, various satellite datasets and supplementary real-time visual media are utilized to construct an advanced 3D modeling workflow. The thesis details the entire process, from data preprocessing through modeling and animation, culminating in post-processing and video editing. The final output includes five distinct video animations, each depicting the wildfire spread from different perspectives. The effectiveness of the workflow is assessed by comparing the animations with an official fire progression report, leading to a discussion on the successes and challenges associated with the datasets and the developed workflow.
