This is a Space Shuttle radar - C (SIR-C) L-band HH polarization image of Maui. It was collected in April 1994. This image replaces the low resolution one that we originally had here since we have now processed the full resolution data. In this image, the difference in erosion between West Maui (at left) and East Maui (otherwise known as Haleakala) to the right are strikingly clear. This is because West Maui is a much older volcano than East Maui.
These data provide almost complete coverage of Maui at a resolution of 25 m/pixel. To show you more of the details, but to keep the image file sizes small, we have highlighted three areas of Maui, and have provided close-up views. Area A ( [600x435 JPEG] or [300x217 GIF] ) shows West Maui volcano. We have some good ground photographs of this area on our Virtual Field Trip of Maui, but the air photographs on this tour suffer from the extensive cloud cover over the mountains. Radar, because it is unaffected by clouds (due to the long wavelength), provides much better views. Area B ( [1028x1229 JPEG] , [514x614 JPEG] or [257x307 GIF] ) shows the S.W. Rift Zone of East Maui volcano. We also get a close view of Haleakala Crater in Area C ( [576x626 JPEG] or [288x263 GIF] ). Although it is off the bottom of this image, we have also obtained a fine view of part of Kahoolawe island, which is Area D ( [326x536 JPEG] or [163x268 GIF] . This is SIR-C Data Take 122.2 from the first SIR-C mission.
The Canadian Space Agency/Agence spatiale canadienne also has a wonderful radar image of Maui acquired by RADARSAT.
