[Gdal-dev] How to split multi-layer geotiff images

[Clay, Bruce]

 I have had problems getting this message posted.  - the send keeps
timing out.  I apologize if multiples finally get sent out

 

 

Can GDAL be used to open multi-layer Geotiff raster files?

 

Not multi-band but more than one image in the same file. I was given
some Geotiff images that Microsoft Office Imaging tool shows 2 distinct
images in a single tiff file.

 

IDL was used to create the file using an APPEND function.

 

ArcMap does not seem to be able to find the second images so I would
like to extract the image using GDAL but I don't see any info in the
documentation.

 

Tiffsplit in the FW tool set will split the file into 2 images but it
kicks up some error messages

The resulting images have no spatial reference information in them.
