INTRODUCTION



These images were processed from a raw format using 

Integrated Software for Images and Spectrometers (ISIS) to 

perform radiometric corrections and projection.  All the 

images were projected in sinusoidal using a center longitude 

of 0 degrees.  There are two versions of the mosaic, one 

unfiltered (sinusmos.tif), and one produced with all images 

processed through a box filter with an averaged pixel tone of 

7.5 (sinusmosflt.tif).  Both mosaics are ArcView-ArcInfo(2) 

ready in TIF format with associated world files (*.tfw).   



Acknowledgements:



The author would like to thank the following people for their 

help and training that made these mosaics possible: Kenneth 

Tanaka, Trent Hare, Jim Skinner and Sarah Hamiln.
