One thing that I ended up doing when reading the metadata was to use the vsicurl driver to access the tiffs, so only the required portions were fetched. His example actually mounts the whole bucket as a file system in which case things are much easier. </div><div><br></div><div>I will note that when using vsicurl to access GeoTIFFs in S3 I found I had to set the following configuration variables to get it working.</div><div><br></div><div><div> # Various /vsicurl hackery to get it working with signed aws urls well</div><div> gdal.SetConfigOption('CPL_VSIL_CURL_ALLOWED_EXTENSIONS', 'ter')</div><div> gdal.SetConfigOption('GDAL_DISABLE_READDIR_ON_OPEN', 'YES')</div><div> gdal.SetConfigOption('CPL_VSIL_CURL_USE_HEAD', 'NO')</div></div><div><br></div><div>I do quite a bit of stuff here with MapServer from S3, but I usually fetch from S3 and store in /tmp for serving so by the time MapServer sees the file it is completely normal.</div><div><br></div><div>Best regards,</div><div>Frank</div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Nov 4, 2014 at 2:56 PM, Robert Sanson <span dir="ltr"><<a href="mailto:Robert.Sanson@asurequality.com" target="_blank">Robert.Sanson@asurequality.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Does anyone have experience with using Amazon S3 to store GeoTIffs for use as a back-end datastore accessible by Mapserver in order to create a WMS service?<br>
