WebIn ArcGIS, there are several methods available for interpolation, spanning from deterministic (e.g. Inverse Distance Weighting---IDW) method and Stochastic (e.g. all sorts of kriging) methods. WebFirst, create a polygon using the draw tool around the outline of the site you want to do IDW for. Under the draw menu bar click "convert to graphics" and save the polygon as a layer. Then go to Geoprocessing->environments. Under the "Processing Extent" tab dropdown to set as the layer of the polygon you just created.
