“…The identification accuracy for maize may be very low if only the features from a single metric are used [17]. To solve this problem, many researchers have attempted to combine multiple metrics, such as vegetation indices [18,19], multi-spectral reflectance [20] and phenological metrics [21,22]. However, these metrics are always constrained by the high demand of simultaneity about high spatial and temporal resolution of remote sensing images which is difficult to be reached currently.…”

“…The phenology-based crop identification is a combination of phenology and vegetation indexes, which had been effectively applied to multi-year maize classification in the Hetao Irrigation District [11]. This method considered the differences of growth stage and growth condition to identify crops.…”

“…Survey of crop planting structure was carried out in Hetao Irrigation District during 28 to 30 August 2012 [11]. We obtained 41 sampling sites of maize and 53 sampling sites of sunflower using the Global Positioning System (GPS), which has a positioning accuracy of 2 m-5 m (Figure 1).…”
