The original GeoTIFF specification was somewhat vague on the implications of using PixelIsPoint? and PixelIsArea? in 2.5.2.2. Some users fell into the trap of thinking that these were only a sampling technique clue and did not affect the real coordinate system. This is not the evolved industry consensus, and the specification needs to make this very clear. Some detail on this issue is captured in: http://trac.osgeo.org/gdal/wiki/rfc33_gtiff_pixelispoint
