  Abstract: Crop species separation is essential for a wide range of agricultural applications—in
  particular, when seasonal information is needed. In general, remote sensing can provide such
  information with high accuracy, but in small structured agricultural areas, very high spatial resolution
  data (VHR) are required. We present a study involving spectral and textural features derived from
