S. CONCLUSION 
U.S. government remote sensing satellite programs including 
NOAA, Landsat-7 and EOS are designed to acquire image data 
suitable for land resource mapping applications. These 
programs are long-term commitments to global monitoring 
with an emphasis on continuity with existing satellite 
programs. Over the next five years the increase in data 
acquisition will be accompanied by advances in image 
processing and mapping applications, particularly in the 
integration of remote sensing and GIS for modeling global 
change.
