USGS Spectroscopy Lab
Yellowstone National Park
studies of Yellowstone National Parks include mapping of:
- Surficial mineralogy,
- Vegetation studies,
- Research on specific ecosystems, including
the grizzly bear habitat.
Raymond F. Kokaly measures the spectrum of a kaolinite hot spring. The kaolinite composition was identifed by AVIRIS Tricorder mapping and
verified in the field. Photo by Roger N. Clark. Click on image for larger, 173K jpeg image.
The current study and status
(Flight line map, 80k gif)
(larger Flight line map, 205k gif):
- AVIRIS data from 1996
- Specific locations in the park, includes (along with some of our results
we will be reporting on):
- Mammoth Hot Springs area (carbonates terraces mapped, vegetation species mapping)
- Norris Geyser Basin (hydrothermal systems mapped)
- Upper and Lower Geyser Basins (hydrothermal systems and biotics mapped)
- Old Faithful area (hydrothermal systems and biotics mapped, including active
systems and older partly eroded inactive systems)
- Grand Canyon of the Yellowstone (hydrothermal systems mapped--the canyon cuts a cross-seection into the hydrothermal zonation)
- Mount Washburn (Whitebark Pine mapped for grizzly bear habitat)
- Lamar Valley (vegetation species mapping)
- AVIRIS data from 1997
- Specific locations in the park, including:
- Mammoth area
- Norris Geyser
- Old Faithful
- Grand Canyon of the Yellowstone
- Lamar Velley
- Yellowstone Lake
- Low altitude AVIRIS data from 1998
- >Specific locations in the park, including:
- Old Faithful (data calibrated, mapped and used in our August field checking).
- others but sensor had problems
- Low altitude AVIRIS data from summer 1999
- >Specific locations in the park (details to be made; see JPL AVIRIS data
facility for now)
- AVIRIS calibration to surface reflectance complete (8/97).
- Initial Tricorder
- Initial field checking complete (Sept, 1997).
- Additional field checking complete (Summer 1998, Oct, 1998, Aug 1999).
- ER-2 high altitude IR photography acquired, and digital scanning (3.7-meter/pixel spatial
resolution) for all AVIRIS flight lines still to be done. Full
resolution images will be ~45 MBytes each. (See examples under our Arches N.P. page.)
- Revised Tricorder
mapping partially complete and products will continue to be produced over
the coming months.
