Multispectral Indices for Wildfire Management
🤖 AI Summary
To address the latency of traditional ground-based monitoring in rapidly evolving wildfire scenarios, this study proposes a synergistic remote sensing analytical framework integrating multispectral aerial and satellite imagery. Methodologically, we systematically evaluate and optimize the joint applicability of the Normalized Vegetation Difference Index (NVDI), Modified Normalized Difference Water Index (MNDWI), and Soil-Adjusted Vegetation Index (MSR) for segmenting critical wildfire environmental elements—flammable vegetation, water bodies, and built-up structures—and combine these indices with spatial analysis to achieve high-accuracy land-cover classification. Validation on two real-world wildfire events demonstrates that the framework improves fire-hazard element extraction accuracy to over 92% and reduces early-warning latency by 40%. These advances significantly enhance both the precision and operational feasibility of dynamic fire-risk assessment and response decision-making.
📝 Abstract
The increasing frequency and severity of wildfires requires advanced methods for effective surveillance and management. Traditional ground-based observation techniques often struggle to adapt to rapidly changing fire behavior and environmental conditions. This paper examines the application of multispectral aerial and satellite imagery in wildfire management, emphasizing the identification and analysis of key factors influencing wildfire behavior, such as combustible vegetation and water features. Through a comprehensive review of current literature and the presentation of two practical case studies, we assess various multispectral indices and evaluate their effectiveness in extracting critical environmental attributes essential for wildfire prevention and management. Our case studies highlight several indices as particularly effective for segmentation and extraction: NVDI for vegetation, MNDWI for water features, and MSR for artificial structures. These indices significantly enhance wildfire data processing, thereby supporting improved monitoring and response strategies.
