The Hyperion scene of WRS2 path/rows 182/42–43 were acquired three days prior to the L7/L8 scenes. This desert site is located within several hundred kilometers of the North African desert site, Libya 4, which is well known for temporal stability. The other site, WRS2 path/row 198/39 is less uniform with substantial variation of ground structure; however, the Hyperion data was acquired within 20 min of L7/L8 imaging. Table 1 shows the metadata for the scenes used. As an example, Figure 3 shows the Hyperion, ETM+ and OLI data over path 198 row 39. Since the swath of Hyperion data is much smaller than L7/L8, small common Regions Of Interest (ROI) were chosen carefully to cover all three geo-registered images. As L8 was in a lower orbit, the pixel size of OLI underfly images was less than 30 m (approximately 29.3 m)
