I want to run gdaladdo on approx. 500 images all sitting in the same directory. <br><br>I have tried the command <br><br>D:\TestGisData\>gdaladdo --config USE_RRD YES *.jpg 3 9 27 81<br><br>and I get the error: <br><br>
ERROR 6: The JPEG driver does not support update access to existing datasets.<br><br>ERROR 1: Attempt to extend field string in node past end of data,<br>not currently supported.<br>Overview building failed.<br><br>Since the command D:\TestGisData>gdaladdo --config USE_RRD YES 01.jpg 3 9 27 81<br>

0...10...20...30...40...50...60...70...80...90...100 - done.<br><br>works, I assume that there isn't a 'wildcard mode' and that I will need to write a dos shell script to do a batch run. <br><br>Can anyone point me to an example of a script like this? I did a lot of searching, but couldn't find anything. <br>
