Abstract
This particular research aimed to analyze spatial distribution of infectious disease patients using dasymetric method comparing with areal interpolation technique. This study used infectious disease patient statistical data between 2014 and 2016 provided by subdistrict health promoting hospital (HPH) located in Phlaichumphon, Banklong, Chomthong, Bankrang, and Watchan subdistricts. Land use was classified into 4 categories including residential, agricultural land, forest, and water resource. Furthermore, spatial infectious cases data was utilized together with classified land use data in order to investigate the infectious disease distribution using dasymetric method and areal interpolation method. The results showed that the rate of infectious patients in residential area was 25.75 per 1,000 inhabitants and the rate of non-residential area was 24.92 per 1,000 inhabitants. The highest rate of infectious disease was found in the residential area of Chomtong district. Moreover, the comparison of coefficient of variation (CV) between dasymetric and areal interpolation techniques showed significant difference. The dasymetric method had significantly lower average rate of infectious disease than the areal interpolation.
