[FWTools] gdaladdo bigtiff error

[jjknoops at netscape.net]

 I found the cause of the problem.
The tif's where I tried to add the overviews to where generated without bigtiff support. And then you can't add overviews to them. 

The solution is that, if you have image that are bigger or almost as big as 4 gb then you need to turn the bigtiff support on when you create them.

I preparing data to be used in mapserver. Now I have tiff files bigger 4 gb. With the bigtiff support I can create tiff from img files. But when I try to add overviews to them I get error:

" .... 

ERROR 1: TIFFWriteEncodedTile() failed.

ERROR 1: TIFFAppendToStrip:Maximum TIFF file size exceeded

ERROR 1: TIFFAppendToStrip:Maximum TIFF file size exceeded

ERROR 1: TIFFWriteEncodedTile() failed.

...

"

I am using fwtools version 1.4.1 for windows XP.



It looks like there is no bigtiff support for gdaladdo. Is my assumption wright? Or did i make an error somewhere?



Is there is no support for bigtiff in gdaladdo what image format works the fastest in combination with mapserver? 



Best regards,
