of EOSAT Landsat Thematic Mapper (25 meter data from a scene recorded on June 30,
1994) for the Moxa Arch area of southwestern Wyoming. USGS 7.5 minute quadrangles
covered by the vegetation map include: Church Butte, Church Butte NW, Cow Hollow
Creek, Fontenelle, Fontenelle SE, Granger, McCullen Bluff, Moxa, Sevenmile Gulch,
Shute Creek Lake,Verne, and Whisky Buttes.
Spectral band ratioing of the Landsat Thematic Mapper was used to distinguish
between the various vegetation types. In all, eleven types were distinguishable:
low density sagebrush, high density sagebrush, greasewood/mixed shrub,
saltbush/playa, playa/barren, riparian scrub/shrub, riparian forest, wet meadow,
industrial, agricultural wet meadow, and water.
V. Herren, BLM Kemmerer Resource Area Office, conducted ground truthing of
the vegetation classifications.
