Spatial relationship analyzing device for heatwave vulnerability and vulnerable class distribution area according to urban heat island and method thereof

A spatial relationship analyzing device for heatwave vulnerability and a vulnerable class distribution area according to an urban heat island, comprising:

• a data collection unit configured to collect satellite image data to calculate land surface temperature, collect vulnerable class population distribution data from a predetermined external population DB, and collect heatwave shelter facility location data from a predetermined external facility DB;
• a DB construction unit configured to store and construct land surface temperature data, vulnerable class population data and heatwave shelter facility number data outputted from the data collection unit, in a land surface temperature DB, a vulnerable class population DB and a heatwave shelter facility number DB, respectively;
• a heatwave vulnerable area and vulnerable class distribution area assessment unit configured to calculate the frequency of daily land surface temperature equal to or higher than a predetermined temperature for each predetermined grid unit, and generate a vulnerable class and heatwave shelter facility distribution for the corresponding grid unit;
• a spatial correlation analysis unit configured to analyze local spatial autocorrelation on the basis of heatwave occurrence frequency, and calculate a local spatial autocorrelation index;
• and
• a spatial relationship evaluation unit configured to assess a facilities targeting vulnerable class location index using a spatial vulnerability index for populations, a heatwave shelter facilities location index and the local spatial autocorrelation index.
