Dear David, Line 1 - x size of a pixel in metres (usually) Line 2 - rotation term Line 3 - rotation term Line 4 - y size of a pixel in metres (image starts at top left and this is downwards hence the minus sign) Line 5 - centre point of top left pixel in x. Line 6 - centre point of top left pixel in y.
Do you think the pixel size is really 0.5 of a mm? Or from looking at line 5 is the image unprojected and in decimal degrees?

Actually a Google search pulled up tfwread-48.zip in www.directionsmag.com but interestingly the Directions Mag own search engine doesn't find any file when I search on TFW - no idea what is going on there... Slight problem - tfwread-48.zip doesn't seem to work, but I'm wondering whether I have been supplied with bad TFW files? One TFW file looks like this: 0.00050000000000000001 0 0 -0.00050000000000000001 108.23932078473548 4.7244404076516631 consisting of 6 lines. tfwread-48 converts it to: !table !version 300 !charset WindowsLatin1 Definition Table File "BINTULU.tif" Type "RASTER" (108.23932078,4.72444041) (0,0) Label "Pt 1", (108.23982078,4.72444041) (1,0) Label "Pt 2", (108.23932078,4.72394041) (0,1) Label "Pt 3" CoordSys Earth Projection 1, 104 Anyone know the definition for TWF files? My TIFF is 9962x7056 pixels, so the 0,0 and 1,0 and 0,1 don't look right to me.
