The primary contention of this commentary is that data sharing requirements will make on-farm research increasingly difficult while also not achieving the stated purposes of opening data. De-identification of farm geospatial data is not sufficient to protect privacy, reducing likelihood of participation in research. Moreover, de-identified farm geospatial data will have greatly reduced reusability. Limited guidance is available on appropriate mechanisms for sharing of farm geospatial data.
