<div>Hi guys,</div>
<div> </div>
<div>I've posted this question in the MapServer list, but I did not get any reasonable solution, I'd like to post it here again, hope somebody can give me some clues.</div>
<div> </div>
<div>I have a subfolder of GIF raster image, and each GIF file has a corresponding TAB file, which specifies the coordinate information for the GIF image, the content of the TAB is something like this:</div>
<div> </div>
<div>***<br>!table<br>!version 300<br>!charset WindowsLatin1
<p>Definition Table<br> File "m_1_1_1000.gif"<br> Type "RASTER"<br> (5.290517,48.2308475) (1392,987) Label "Pt 1",<br> (5.25001439194036,48.25) (0,0) Label "Pt 2",<br> (5.25001439194036
,48.211695) (0,1974) Label "Pt 3",<br> (5.33101960805964,48.25) (2784,0) Label "Pt 4",<br> (5.33101960805964,48.211695) (2784,1974) Label "Pt 5"<br> CoordSys Earth Projection 1, 104<br> Units "degree"
<br>***</p>
<p>but if I perform the gdaltindex command to create a tile shapefile for the images, an error occurs:</p>
<p>>>no georeferencing info available for the images file, performance will be skipped.</p>
<p>and I also get some info from the "Raster Data Access" document, "The only way to georeference GIF files is with a world file. ", is it really so?if it's true, there will be a huge project for me to change all the TAB files.
</p>
<p>hope that someone can help.</p>
<p>thanks so much for any info.</p>
