Fig.1. P40/R30, Landsat 7 ETM+ 4/8/2000, Colored T s image(left, 284K:Blue to295K:Red) and the true color image (right).The coordinates of the inquire cursor are x/y =436892/194372)First, let’s focus on the northwest region. There are many cold pixel candidate fields in thisregion. Some of the candidate fields are circled in Figure 2.Fig.2. P40/R30, Landsat 7 ETM+ 4/8/2000, Colored T s image (left, 284K:Blue to295K:Red) and the false color image (right).The coordinates are x/y = 435805/188719)One of the candidate fields is displayed (marked by the cross-hairs) at the center of thenext image (Figure 3). The temperature is quite homogeneous in the field, around 289.5 K.This is a good candidate field because the false color image indicates a high intensity ofvegetation. In addition, there are some fields in other areas having similar temperatures.Based on the local area (south-central Idaho) and time of this image, this field is probablyfull cover, well-watered, winter wheat.68
