Hello again,
I saved this file as layer file. Try open ArcScene, select File, Add Data, Add data, then select Kriging_shp3.lyr. You might notice that there is a donut shape around center of the layer. The donut shape is a part of edge effect. You might try to measure the distance from the edge of the forest to the donut and also the area in the center. The distance from the edge may be proportion to the size of the forest, and the area in the center may have cause by wind turbulence. This is some idea that you can write in your project, ok? Read more about it and you can find more things to write. p'ray
