Data Integration and Manipulation
The nine (9) factors were reclassified and weighted according to the result of AHP defined in the previous step, these forms the thematic layers (soil quality, water quality, and physical condition) that were used then in suitability analysis. Since the raster data type was used in all of the analysis in this study, overlay of themes were done using the ArcGIS raster calculator. Operations from the simple addition and multiplication to the creation of complex logical/conditional statements of raster data were performed to generate the final suitability map. Each pixel size was 10m x 10m.
