Selon Peter Hopfgartner :
I'm not sure of your exact plans, but if you want to switch to internal libtiff
4 with GDAL 1.8.1, you might get into problems with applications that link both
with GDAL and external libtiff 3.9, because of symbol conflicts. If you switch
your external libtiff to libtiff
Hi Evan
Indeed, the external libtiff is used and is version
libtiff-3.9.4-1.el6_0.3.x86_64.
In the mean time I did a quick compile of gdal-1.9.0 with internal
libtiff and the square disappeared.
Probably it would be a wise decision to switch to libtiff4 quickly, as
far as ELGIS is concerned.
Peter,
Does ELGIS GDAL uses internal libtiff (4.0beta) or external libtiff (3.8 or 3.9)
? I guess it is external libtiff, and then it could explain the issues you have
with overviews and JPEG compression. There have been fixes in libtiff 4 to
better support that situation (multiple IFDs with compr
I'm doing quite some experiments with GDAL and image compression these days
I do have an issue with geotiff 1.3/gdal 1.8.1 on CentOS 6 with packages
from ELGIS. The story goes like this:
I create tiffs with
gdal_translate -of GTiff -co COMPRESS=JPEG -co JPEG_QUALITY=90
-co "TILED=YES" -co "B
