Creating "like" zones based from Raster NIR Image

Discussion created by bryanarn on Jun 17, 2014
I am trying to create similar "management zones" based on the similar areas of soil properties from a color NIR image. My process has been to convert the raster to points, use IDW, reclassify, and then convert that to polygons. However, I am getting too "choppy" and irregular looking results. Does anyone have an idea of a process that may work well? I attached a screenshot of my original raster on the right, and an example of the type of result I am trying to achieve on the left. Thanks for any help!
