研究目的
Comparing two forest fire probability mapping techniques, one based primarily on freely distributed EO data from Landsat imagery, and another one based purely on GIS modeling, to evaluate their ability to map forest fire probability for a region in India.
研究成果
The EO-based technique was found to be the most suitable option for forest fire probability mapping due to its lower computational requirements. The fusion of EO and GIS-based approaches offers a robust method for identifying high fire probability zones, aiding in forest conservation and fire management strategies.
研究不足
The study is limited to the Jambughoda Wildlife Sanctuary in India, and the techniques may need adjustments for application in other regions. The GIS-based approach requires more computational time and resources compared to the EO-based technique.
1:Experimental Design and Method Selection:
The study compared two techniques for forest fire probability mapping: an EO-based technique using Landsat imagery and a GIS-based modeling approach. The EO-based technique utilized the Normalized Burn Ratio (NBR) from Landsat data, while the GIS-based approach employed a multi-criteria evaluation technique incorporating anthropogenic and natural factors.
2:Sample Selection and Data Sources:
LANDSAT TM 5 satellite images of the Jambughoda wildlife sanctuary in India were used. Two images with acquisition dates 23rd October 2009 and 01st April 2010 were analyzed.
3:List of Experimental Equipment and Materials:
ENVI (v. 5.1, ITT Visual Solutions) and ArcGIS (v. 10.1, ESRI) software platforms were used for analysis. LANDSAT TM 5 satellite images were obtained from the United States Geological Survey (USGS) archive.

Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: The EO-based technique involved calculating NBR from Landsat data to detect fire severity and probability areas. The GIS-based modeling involved multi-criteria evaluation with weighted factors. Both techniques were validated using field surveys and GPS data.
5:Data Analysis Methods:
Descriptive statistics, correlation analysis, and performance statistics were used to evaluate the effectiveness of both techniques. A data fusion approach was also explored to combine the strengths of both methods.
