<p class="MsoNormal">I noticed a warning after converting a gtiff image to jp2 stating ‘Warning 6: Unhandled projection method Albers_Conic_Equal_Area’. The driver apparently completes the conversion and happily reports the projection correctly under gdalinfo.
But I find it weird that the format would care about the projection. Is this a serious warning?<o:p></o:p></p>
</blockquote>
<p>It is a bit strange that you get this warning (especially since this should be a projection method handled by GDAL) and get a SRS after the projection.<o:p></o:p></p>
<p>It is fully expected that the JP2OpenJPEG driver tries to get georeferencing from the metadata. There are several ways to embed georeferencing in a JPEG2000 image : GeoJP2, GMLJP2. All JPEG2000-capable drivers in GDAL share the same code to read that georeferencing
when present and expose it.<o:p></o:p></p>
<p>Any link to that JP2 image? (sometimes images have both GeoJP2 and GMLJP2, or possibly a side-car file. I'm wondering if the warning might not come from an attempt at reading with one method, and finally a fallback is used)<o:p></o:p></p>
