Forest Fire Prone Area Mapping A Case Study in GIRProtected Area

The following study had been carried out in GIR forest which is located in the Saurashtra Peninsula of Gujarat. It is the largest biologically intact contours tract of forest and the only abide of the Asiatic Lion in the world. The main objective of the study is to design, develop and demonstrate RS/GIS based approach in order to prepare region/type level fire danger rating system taking into consideration risk, hazard, meteorological parameters and human interventions and also to prepare forest fire risk area/disaster map for GIR forest Gujarat. Two types of data are used in the study i.e. spatial and non spatial. Spatial data mainly includes Remote Sensing data, forest block, compartment boundaries, road/railway network and the most important existing water bodies in that area where the non-spatial data pertains to meteorological data on temperature, relative boundary, rainfall, wind, socio-economic data.

The methodology adopted was visual, digital and hybrid method for Remote Sensing data analysis. IRS 1C/1D LISS III FCC's were used for visual interpretation for classification of vegetation in the entire GIR-PA region. To identify fire scars digital data of IRS 1C/1D WiFS had been used. WiFS data had also been used to delineate water bodies and fire scars. The parameters used for modelling the fire risk zone were -

• Fire occurrence maps for three or more seasons

• Classified vegetation map (two seasons)

• Road network (Proximity analysis)
