I'm using Arcmap 10 and I have scattered points (denser in an area). Each point represents a thickness value. I want to get a raster from this points which I will transform in polygons (raster-to-polygons). Which is the best interpolation tool for this operation? I tried them and I saw the "kriging" tool is the one which gives me the best "overlapping" (i hope it's a good term, forgive my english) of the areas with a certain value of thickness with the points which have that specific value of thickness. Is this an appropriate way of establishing which tool is the one the suits better to my case?
