Analysis and Interpolation of Water and Soil Parameters
Water and soil samples were sent to laboratory to analyse pH and salinity. And the results were encoded and entered into a GIS database with their corresponding coordinates. Then these parameters/data were spatially interpolated using Kriging method in Geostatistical Analyst tool of ArcGIS 9.3 to derive data over the entire area. Different Kriging models were developed and their prediction errors were checked to choose the best model.
