Vegetation Mapping Using Remote Sensing and Geographic Information System Technique at Pusch Ridge,Tucson,State Arizona, USA[J]. Journal of Remote Sensing, 1995, (1). DOI: 10.11834/jrs.1995005.
The classification accuracy of vegetation mapping by satellite ima- gery in a complex terrain environment can be improved by using ancillary data andimagery spatial features extracted from the images(Richord
1992).Thls study isto test the role of GIS spatial and spectral analysis model in aiding the classifica- tion of satellite data. Three GIS programs is developed
which improve the accu- racy of unsupervised classification for SPOT data from 37.41% to 71.67%. Second objective is to test the ability of two satellite system
SPOT and LandsatThematic Mapper(TM)
in mapping of vegetation in mountain region
Both data areprocessed with supervised classification in-corporating with ancillary data. The ac- curacy with SPOT data is higher than with TM.
