Hi, I have experience about spatial analysis using different interpolation methods such as IDW, Kriging, Spline, Natural Neighbour, Topo to Raster. I mostly using those methods to interpolate rainfall data from weather station, create topographic maps from elevation points data, and also interpolate household pollutant using natural neighbour to create heatmaps (pollutant concentration). What are the interpolation method that you want to use? We can discuss more on chat, or you can give me a sample of your data and then I'll make a preview for you.
