<P><FONT face="Courier New" size=2>Hi Frank, Dave and Bern,</FONT> </P>
<P><FONT face="Courier New" size=2>You may have seen a message on this topic,
but just in case you haven't:</FONT> </P>
<P><FONT face="Courier New" size=2>I have not found this bug in ESRI Support
database, GDAL Bug or enhancement lists or via Google Search.</FONT> </P>
<P><FONT face="Courier New" size=2>I've noticed that ArcGIS Explorer 9.2 (AGX)
creates image pyramid (.rrd)</FONT> <BR><FONT face="Courier New" size=2>and
(.aux) files on image and elevation data in .tif format that</FONT> <BR><FONT
face="Courier New" size=2>ArcGIS 9.2 and GDAL 2.2.6 can not read.</FONT>
<BR><FONT face="Courier New" size=2>My recollection is that both ArcGIS and GDAL
fail catastrophically</FONT> <BR><FONT face="Courier New" size=2>when they
attempt to read these .rrd and .aux files.</FONT> </P>
<P><FONT face="Courier New" size=2>Adding a layer to ArcMap that has an .rrd
file that was created by</FONT> <BR><FONT face="Courier New" size=2>AGX causes
ArcMap to fail.</FONT> </P>
<P><FONT face="Courier New" size=2>GDAL data read .dlls and command line
utilities fail when reading a</FONT> <BR><FONT face="Courier New" size=2>.tif
file that has an .rrd file that was created by AGX.</FONT> </P>
<P><FONT face="Courier New" size=2>I think that AGX overwrites .rrd files
created by ArcGIS when AGX</FONT> <BR><FONT face="Courier New" size=2>loads data
in .tif format, but I don't recall for certain what</FONT> <BR><FONT
face="Courier New" size=2>happens in this case.</FONT> </P>
<P><FONT face="Courier New" size=2>The attached Python script will delete .aux
and .rrd files from a directory structure recursively.</FONT> </P>
<P><FONT face="Courier New" size=2>Thanks!</FONT> <BR><FONT face="Courier New"
