FIPS 5103 to Geographic reprojection is not working
Mike,
I used your shortcut (UTM Code = FIPS code) for Hawaii State Plane zone 3 - 5103, but now when I try to re-project those points using either ProjectRectangle or ProjectPoint/List, the values returned are "off" to the NW by about 300mi. I'm assuming this is because when you look at the mNativeProj I pass in to the functions, its missing those mAttrs I would have normally had to fill in myself (FALSE NORTHING, etc.).
Can you confirm this behavior? Do you need more info?
I'm going to attempt to pass in a projection with all of the 5103 attributes and not the mNativeProj I initialized from 5103 and see what happens.

Brian,
You shouldn't need to fill in the attributes, they are implied by the ZONE=5103. However, what datum are you using? The definition of that zone is different depending on whether you are using NAD27 or NAD83.
Thanks,
Mike

Mike,
I'm an idiot. I had my linear unit in feet instead of meters (while troubleshooting something else) Its all working beautifully. Thanks!
