Riki,Please let us know whether Frank's suggestion works or not. I have been experimenting with writing GeoTIFFs using GDAL 1.6.0 and the Python bindings and have not been successful so far at using GDAL to calculate statistics that ArcGIS recognizes. It would be interesting to know whether this suggestion will work. If anyone is interested, after creating a GTiff with one band, writing values to the band, flushing the cache, I have been calling band.SetStatistics(*band.GetStatistics(False, True)) and then looking at the resulting file from ArcGIS 9.3.1 (the latest version). ArcGIS reports that there are no statistics. I can then calculate them with ArcGIS, if desired, but like Riki, it would be useful if I did not need to do this.
Jason, I notice that if I run gdalinfo -stats from trunk I get the stats written to the .aux.xml file while I don't from the 1.6 branch. I think this is something that has been fixed recently. I'd suggest working from trunk if that is at all practical. If it is important, I could backport some of the statistics retaining fixes back to 1.6 branch.
