[FWTools] gdal2tiles: Working Version?

[Gregory Yetman]

Hi,

I wanted to try the gdal2tiles function in FWTools but it seems to be 
broken with the latest FWTools. Is there a version where it is known to 
work? I think that the issue is because of changes in GDAL at 1.7 but 
I'm not sure how to tell which version of GDAL comes with FWTools short 
of downloading and installing them.

I've including details of the problem with gdal2tiles in FWTools 2.3.1 
(Windows) below.

Thanks,

Greg

Command issued was:

gdal2tiles --s_srs=EPSG:4326 --zoom=6 --force-kml 
--url=http://localhost:8080/ --webviewer=none Population_Density_2005.tif

gdal2tiles.py: error: This version of GDAL is not supported. Please 
upgrade to 1.6+.

gdal2tiles.py seems to be breaking here (line 537):

try:
     if (self.options.verbose and self.options.resampling == 'near'): or 
gdal.TermProgress_nocb:
                 pass
except:
     self.error("This version of GDAL is not supported. Please upgrade 
to 1.6+.")

If I remove the gdal.TermProgress condition I get an message that the 
average method is not supported:

gdal2tiles.py: error: 'average' resampling algorithm is not available.

I tried specifying the 'near' method, it fails on GetMaskBand():
