Only for the most 
recent evaluations 
of the AGF- 
Working Group published here, operational radio- 
metrically corrected data sets were available. 
The Thematic Mapper data used for the comparison 
were radiometrically and geometrically corrected 
and resampled using cubic convolution interpolation 
to a 28,5 meter grid during the ground processing 
as part of theTM Image Processing System (TIPS) at 
Goddard Space Flight Center. 
The comparative analyses of digital data at 
NASA/GSFC war carried out the following way: 
- rotate MOMS dara 90 degrees counterclockwise, as 
both system's orbit inclinations are nearly 
perpendicular; 
- select common ground control points; 
- register TM bands 2, 3 and 4 to MOMS bands using 
second order polynomia coordinate transforms and 
nearest neighborhood resampling;
