Image 1:
This mosaic of 13 transects can be browsed at 6 meters/pixel resolution. (Original data was collected at 1.5 m/pixel.)

The va (visible red band) is shown in red; vb (near-IR band) is shown in green; ir4 (wide-band thermal IR) is shown in blue.

Image 3:
The va (visible red band) is shown in red; vb (near-IR band) is shown in green; NIR ( IR) is shown in blue.

This image is from the start of Pass 6, the first transect from the south.

Bare soil reflects in all bands, appearing white; bare rock is magenta.

Image 4:
The va (visible red band) is shown in red; vb (near-IR band) is shown in green; ir4 (wide-band thermal IR) is shown in blue.

This image is from the start of Pass 11, the fourth transect from the south.

Fresh ash layer from a recent fire absorbs solar energy, radiating strong thermal IR (in blue).
