Hello Norm

I do not contest what you said. My email was only suggesting to write that down, 
since the current GeoTIFF specification said nothing about axis order and the 
GeoTIFF tables specify (lat,long)...

	Regards,

The end result after experiencing many years of agony and pain would be pretty much what we have now as technology advancement would have to take a big hit to provide the resources to achieve "axis order correctness".
