<p class="MsoNormal">Hi,<u></u><u></u></p>

<p class="MsoNormal"><u></u> <u></u></p>
</div>
<div>
<p class="MsoNormal">Is it possible to configure one raster layer with a single output projection (epsg:4326) where input rasters are in different UTM zones? I'd like to avoid reprojecting the source data if possible.<u></u><u></u></p>
</div>
<div>
<p class="MsoNormal"><u></u> <u></u></p>
</div>
<div>
<p class="MsoNormal">The rasters will be determined from a Postgis-based tile index where raster extents are stored in epsg:4326. The database will also track what UTM zone the source raster is in. Is it possible to pass this projection info from the database
to the PROJECTION block?<u></u><u></u></p>

<p class="MsoNormal">When I make a WMS request for test in an area where the images overlap, it seems MapServer stops rendering rasters after the first image in the tile index is found... so in this case since zone45.tif was the first image in the tile index,
that's what I see for a request bbox in the overlap region. If I swap the order of files in the command to build the tindex, the overlapped area only shows me zone46.tif.<u></u><u></u></p>
