Also i will be collecting filed data for these parameters from the study area so how can i point out each sample location just like you did for ticks please reply.

    Hello, the research link you provided based on AHP, Table 5 there had values like 0.156, 0.118, 0.178 and so on form DEM, Slope, and Rainfall and so on. But here in your slide, its tiny bit different, is it because assumed just these 5 values and and found average yourself, or did you referred other books or papers?
