I have received some maps from OS. The CDs contain .tiff files and .tfw files. When I try to open them in ArcGIS the reference information is missing and the .tiff is located at 0,0 location. How can I link .tiff to .tfw.
in here World files for raster datasets—Help | ArcGIS for Desktop
there is a section called ... Set ArcGIS to read the world file first ....
that might do it
