The <br />base is a copyrighted satellite image (used with permission) provided by Digital Globe. <br />Temperature in the thermal image is displayed as gray -scale values, with the brightest pixels <br />vindicating! the hottest areas (white shows active breakouts). During the overflight, fissure 7 <br />stands out as the first fissure to produce a small lava flow. When the thermal images were <br />collected, the flow was about 260 m (853 ft) long. The thermal map was constructed by <br />stitching many overlapping oblique thermal images collected by a handheld thermal camera <br />during a helicopter overflight of the flow field. <br />10 <br />
