Though all of the date for this frame point to 2014, this is only when a set of additional strata was added to the frame. For the survey year of 2014 the Cropland Data Layer was used to add a layer that is durum wheat. Before this, the entire state was stratified to Landsat satellite imaging and completed for the survey year 2011.

Data sources used in this process:
The sources used for digitizing strata boundaries are 1:100,000 scale Digital Raster Graphics
There are known gaps and overlaps. This data set includes the area in square miles and number of acres for each strata. Boundaries may not be coincident with strata boundaries of adjacent states.
Checks for topological consistency were performed on this data set.
