<br>
The .RPB are perfect good example of RPC and GDAL reads it pretty
well, although it is a little bit strange that gdalinfo reports
the Reference System and GeoTransform matrix completely
dissociated from the RPC but I think it does makes sense, since
most of the applications will not process the RPC geometric
transformation anyway.<br>
<br>
I didn't know that Jared was looking specifically for *internal*
RPC tags. He just said "<font face="Calibri, Verdana, Helvetica,
Arial"><span style="font-size:11pt">GeoTIFF with RPC</span></font>".
If the GTIFF driver could write the RPC he could "gdal_translate"
(a verb) the .TIF/.RPB to a GeoTiff with *internal* RPC. Would
that work? By the way, does GDAL support RPC on any other file
format as auxiliary xml?<br>
<br>

<div>Ivan / Jared,</div>

<div>I fetched the dataset and isolated the following file</div>
<div>and it did not have RPCs internally:</div>
<div><br>
</div>
<div>
05JUL04180116-P2AS-005554608080_01_P001.TIF</div>
<div><br>
</div>
<div>I see there is a parallel .RPB and .IMD file which GDAL</div>
<div>reads for metadata but this is *not* an example of the</div>
<div>RPC coefficients within the TIFF file if that is what you</div>
<div>were looking for. </div>
<div><br>
</div>
<div>I'm referring to:</div>
<div><br>
</div>
<div> <a moz-do-not-send="true"
href="http://geotiff.maptools.org/rpc_prop.html">http://geotiff.maptools.org/rpc_prop.html</a></div>
<div><br>
</div>
<div>
If that is what you need, let me know and I'll </div>
<div>try to prepare an example if there isn't one</div>
<div>already somewhere. Note that to GDAL apps</div>
<div>this should look the same as working with the</div>
<div>quickbird image. </div>
<div><br>
</div>
<div>Best regards,</div>
