Reciprocal to gdal_merge.py ?

[pierrick.brihaye@…]

Hi,

Does it make sense to have a utility reciprocal to gdal_merge ? gdal_split or
something like this.

The purpose would be to generate "tiles" from big raster files and especially
500 Mb uncompressed files for a free ECW compression ;-)

Specific arguments could be :
-of file0000.tif (0000 being a numbering pattern)
-od outputdirectory | -oa outputarchive
-ts width height
-fs 500m
-t_srs

Cheers,

p.b.

A "split into tiles" utility would indeed be useful for a number of purposes. 
I can't say when this might happen, but it is definately worth having on
the enhancement list.

Attaching code for gdalsplit.cpp written by Homme Zwaagstra
(hrz at geodata.soton.ac.uk).  I haven't reviewed and incorporated this into
CVS yet but it should apparently do the job.

Let's revisit this in light of the Summer of Code project.

I think the new gdal_retile.py script accomplishes roughly the same purpose. Closing this ticket.
