1 2) Methodology 
IRS-1C/D and Landsat TM/ETM+ used as a basic data, and 
inflected Digital Map, stock map and Natural Environmental 
map etc. used as a reference data. Image data was chosen that 
0, have been filmed most recently confirming with photographing 
angle, image state and the photographing matter. Ground 
control point was used DGPS measurement data of 1m-error - c S ee. : 
kr, range that possess from the Ministry of Environment. Image ROS TA Her Saag d 
data was secured homogeneity of data by rational special # 
quality uses picture of similar same season. 
Considered so that seasonal clothes special quality may be 
zed classified using satellite image of multiplex time. Fusion image 
of 7 of Landsat and IRS data were applied Radiometric image 
s to fusion method that emission special quality preservation of
