Again, quoting from the manual, this time for r.out.gdal...
When writing out GeoTIFF format for users of ESRI software or ImageMagick,
the band interleaving should be switched to pixel interleaving using
createopt="INTERLEAVE=PIXEL". Multiple options have to be specified as comma
separated list (createopt=TFW=YES,COMPRESS=DEFLATE).
r.out.gdal (.c) help page now updated in 6.3CVS to expand on that a little and
add a ESRI-compatible GeoTIFF example. ... now if someone who uses ArcGIS 9
could please test to see if the example works & report back? :)
Is deflate compression ok for all versions of Arc? We might add that to the
example. (I assume versions of Arc which have come out since the LZW patent
expired allow that, but we might as well keep the example compatible with)
How about r.out.gdal export to binary AAIGrid format? Is that usable+useful?
Folks,
I would add that after years of struggling against packages that don't
support pixel interleaved TIFF files, I have finally given in and changed
GDAL to produce those by default. Also, new versions of ArcGIS should support
pixel interleaved files (starting at 9.2 or 9.3?) I believe.
Best regards,
