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! Bryan ... View more

I have a dense set of yield data points from a harvested corn field in Iowa. I would like to interpolate the data into 60ft grid cells, and then convert the resulting raster into polygons. Each 60ft cell needs to have it's own unique ID and value. I have attached a screenshot of how it looks in the agriculture specific software (on the left) and my attempting result in ArcMap (on the right). Even though I set the height and width of the cell size to be 60ft, it still gives me the contoured look. Thanks for any advice! [ATTACH=CONFIG]30900[/ATTACH] ... View more

I have been doing some research, and I believe a weighted overlay is going to be my best approach, unless someone has other suggestions... My situation....we are a crop consulting company in Iowa, and are working on developing management zones for our growers fields based on multiple layers of data. These data layers include spatial yield, soil types/topography, aerial image of bare soil, elevation data, among others. We would like to overlay all of these to produce polygon management zones for each farm. My main question is do all rasters need to have the same cell size for the analysis to work properly? I'd also welcome any tips or suggestions on how to accomplish this. We ultimately want clean polygons of 5-6 acres each. Thanks! Bryan ... View more

I have two things I'm trying to accomplish. The first is creating a pick list or checkbox list of certain attributes I would like to query to select the features I'm interested in. For example, I have a feature class of field boundaries for all clients we work with.  Each client has a boundary for each year, so within each boundary is an attribute of clientname and year, among some other blank ones such as croptype and plantdate.  I would like a picklist to choose which client and year I would like to select to edit and populate the blank attribute fields. So, it would be nice to have it allow me to select the client name, and the next option would only show the years that the selected client has field boundaries in our system. Is this possible? Next, after the certain boundaries are selected, I would like to create pick lists to populate croptype and plantdate instead of having to manually type them all in with the chance of errors. Any advice would be greatly appreciated! Bryan ... View more
