In the first part I have shown and explained how to prepare factors that influence ground water potential zones. I have prepared factors such as drainage density, lineament density, land use and land cover, geology map, soil category map, rainfall map. Also have shown how to perform reclassification for weighted overlay techniques.
In this video, I have explained how you can perform adding these factors in weighted overlay and also how to do pairwise comparison matrix automatically in a Excel sheet. I have used An AHP automatic excel sheet where you just have to put the criteria and it will automatically generate weighted score and then just input these in the ArcMap. You don’t have to calculate manually weighted score for each criterion. This technique you can use for any risk assessment study like flood risk, landslide, earthquake risk or any kind of risk assessment study.
Please remember that the Projection system and cell size for all of your maps need to be same. Otherwise, you cannot perform the process. It will not give the accurate results. You just need to check for every map that the projection system and cell size are same.
