The latest public version of rgdal, which binds with GDAL 1.6.1, fails with the
error message in the subject line of this email. I reported this a couple of
weeks ago in <a
href="http://lists.osgeo.org/pipermail/gdal-dev/2009-July/021369.html">http://lists.osgeo.org/pipermail/gdal-dev/2009-July/021369.html</a>.<o:p></o:p></span></p>

rgdal built against the 1.6.2 release candidate issued 31 July. The problem
still exists.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Verdana","sans-serif";
color:#003399'>The problem had apparently been seen before. My original email
prompted a review of the issue, including mention of it being tracked in
tickets #2447 and #3031. Evan made some checkins on 22 July that I thought would
result in this being fixed in both the trunk and the next release of 1.6 (which
would be 1.6.2). But I guess I did not fully understand it, and I missed the
fact that neither of these issues appeared in Howard's 31 July release
candidate email.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Verdana","sans-serif";
color:#003399'>So: is there any chance the GDAL team can fix this in either
1.6.2 or, if it is now too late, 1.6.3?<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Verdana","sans-serif";
color:#003399'>It may be that this fell off the radar because the severity of the
tickets (for example, #3031 is minor), or because there was a suggested
workaround that users could simply rename the &quot;info&quot; directory to
prevent GDAL from failing. Well the issue is indeed severe if you are an ArcGIS
user. In my case, the rasters were produced by ArcGIS 9.3.1. Presumably ESRI is
generating the rasters correctly. The workaround of renaming the info directory
is not a good idea. That renders all of the rasters in a directory inaccessible
to ArcGIS. It is a major corruption of the ArcInfo binary grid format to do so.
I'm not sure why it was suggested in the first place, but it is a very bad
idea.<o:p></o:p></span></p>

color:#003399'>I'm sorry for not staying on top of this issue and somehow
missing that it was not put into 1.6.2 and that the workaround is such as bad
idea. In any case, could you please consider fixing this in 1.6 soon? I can
provide example data if needed.<o:p></o:p></span></p>
