rectify a scan chart, doesn't have any options for what math it uses when
generating the Georeferenced chart, so the edges fall off sharply if you can
not get the edges rectified close enough. Also, takes FOREVER to generate
a GeoTIFF! anywhere from an hour to 1.5 hours. I though it was may
machine, so I built a box with the latest and greatest AMD CPU I could find
($1200 ouch!), put 2GB's of fast RAM in there and a 300GB 7500RPM drive with a
dual monitor graphics card. Still takes an hour or more.. ARGH!</span></font><o:p></o:p></p>

coordinate system to each chart. Tried writing VB code using ArcObjects
