<p><span lang="EN-US" style="font-family:"Calibri","sans-serif"">Hi all, <br>
<br>
I hope my email finds you well<br>
<br>
I would like to report you a convention issue with our SPOT6-7 RPC model.<br>
</span><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:black">Gdal has previously updated RPC model interpretation of Pléiades so that image coordinate normalized rn,cn = -1,-1 corresponds to r,c = 0,0 by subtracting 1 pixel
to the offset value in row, column. The problem is that this interpretation was applicable to all Primary products (PHR and SPOT) while it shouldn’t done for SPOT.<br>
<br>
Regarding DIMAP and image file, there is no difference between SPOT and PHR. The pixel convention is center pixel for both<br>
<br>
However regarding RPC : <br>
For PHR, image coordinate normalized rn,cn = -1,-1 corresponds to the image coordinate r0,c0 = 1,1<br>
For SPOT, image coordinate normalized rn,cn = -1,-1 corresponds to the image coordinate r0,c0 = 0,0 (c.f. </span><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:black"><a href="http://geotiff.maptools.org/rpc_prop.html" target="_blank"><span lang="EN-US">http://geotiff.maptools.org/rpc_prop.html</span></a></span><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:black">)<br>
<br>
Could you handle this modification ? Or tell me who is the best contact to address this request ?
<br>
<br>
For information, here is the original discussion six years ago, when you implemented the fix for handling the PHR RPCs correctly:</span><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"> </span><a href="https://trac.osgeo.org/gdal/ticket/5993" target="_blank"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri","sans-serif"">https://trac.osgeo.org/gdal/ticket/5993</span></a><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:black"><br>
<br>
I’m staying at your disposal for any further information if needed<br>
<br>
Have a good day<br>
<br>
Best regards <br>
