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;
