Hi All,
 
Does MapInfo support ModelTransformationTag that is included in geotiff
header if raster image requires rotation and shearing? I was trying to
open several scanned topographic maps and the raster image required
rotation. For this purpose the transformation matrix was build and
values was included in ModelTransformationTag (4,4). MapInfo 7.8 had
opened these rasters in proper geographic model in the meaning of
projection, MapInfo added proper projection but the adjacent scanned
sheets didn't match. Then resampling was made for these rasters and new
geotiffs was produced with exact affine transformation with parameters
included in ModelTiepointTag (2,3) and ModelPixelScaleTag (1,3). It was
good step because all rasters was georeferenced in the proper way. It
was right projection added and there were no shifts between adjacent
sheets. Did i make something wrong or simply MapInfo supports only set
of tiepoints and scaling parameters?
 
Thanks in advance,
