Hi, I have 10 m resolution NRCS DEM data in ESRI grid format. I also have a shape file that contains farmer's fields as polygons. There are about 2500 farmers' fields. I want to use DEM data first to identify if fields is flat, little slope, moderate slope, and hilly. I don't have any idea to set up threshold for DEM data to make various categories. Kindly help on to it. My second assignment is to find if farmer's fields can be classified as upland or lowland based on the landscape of that region but not based on the landscape of the whole studied region. Thanks, Bhupinder

Hi All, I am dealing with farmers' reported data on corn production in Nebraska. I want to use elevation data (10 or 2 m resolution) to create some kind of index that can help me to find either land roughness or something else. For example, if in a small area there are 10 farmers and 2 of them are performing better than others. It would be hard to find climatic differences or differences in soil properties. One possibility is that they might have different agricultural management practices, I don't have that data but other possibilities is that soil/land roughness or position of their farm relative to neighboring farms. I don't have much clue into that so posting to request response of you. Thanks, Bhupinder
