I use FME (Feature Manipulation Engine) from Safe Software, of which modular components form the Universal Translator in MapInfo. Actually, there is a Universal Translator in FME. I was just looking up the 'native MapInfo' projection info within FME, and the documentation states that MapInfo's native Lat/Long projection is in WGS84.

I think the story is that whichever comes first in the MapInfo projections file determines which "signature" you see. So, if you want to see WGS84 moves its definition up in the mapinfo.prj file. If that's wrong, or has changed in later MI Pro versions, I'd like to know.

I really question this because when I set the non-native to NAD27, the coordinates change accordingly. Does anybody know how I can generate the coordinates for WGS84 from NAD83. I m after the X,Y data most importantly. Thanks, Carlo ------------------------------------------------------------------------------ Yahoo!
