Abstract:

To enhance the role of satellite remote sensing data in the planning of aviation emergency rescue layout, this paper introduces a location selection method that integrates satellite remote sensing data with forest fire emergency rescue layout planning. The study encompasses the following key aspects: Firstly, leveraging the MODIS active fire dataset over the years, fire-prone areas are delineated as demand points. Secondly, considering the temporal constraints from fire detection to response, the factors influencing the location of aviation emergency rescue stations are analyzed based on forest fire characteristics. Utilizing ArcGIS software, relevant satellite remote sensing data of primary indicators are parameterized and weighted for superposition, yielding the areas suitable for constructing aviation emergency rescue stations. Subsequently, a set coverage mathematical optimization model is formulated to determine a rational location layout and construction priority. Lastly, through case analysis, the mode
