<p class=MsoNormal>Hi<o:p></o:p></p>
<p class=MsoNormal>I have a question about the RPC transform implemented in gdal_rpc.cpp.<o:p></o:p></p>
<p class=MsoNormal>If a dem file is specified in the transform options
(RPC_DEM) the file is sampled to retrieve the elevation of the transformed point.<o:p></o:p></p>
<p class=MsoNormal>In the case where the dem file is a DTED file (which defines
AREA_OR_POINT to POINT), shouldn't the pixel/line values in the dem file be
offset by half a pixel to get the correct height?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks<o:p></o:p></p>
<p class=MsoNormal>Yehiyam<o:p></o:p></p>
