After getting all the projection sections into my .map file without any correctly-drawn tiles, I've given up on tilemode for now and am trying out tilecache with MapServer's WMS. However, it appears that EPSG:900913 is not known in my system. On a Linux install, where is the list of projections/WKT?<br>
<br>I've tried using upper and lower-case namespace (epsg and EPSG) to no avail.<br><br>I get the following error through tilecache when it attempts to hit my WMS:<br><pre id="line1"><<span class="start-tag">ServiceExceptionReport</span><span class="attribute-name"> version</span>=<span class="attribute-value">"1.1.1"</span>><br>

<p class="MsoNormal">Hi everyone,<br>
<br>
I've spent the better part of today scouring the internet for documentation and
help on the tile mode present in mapserver, but I couldn't find an answer to my
problem, so please forgive me if I'm missing some obvious documentation some
where...<br>
<br>
I am attempting to show some GeoTIFFs (from here: <a rel="nofollow" target="_blank" href="ftp://geoftp.ibge.gov.br/mapas/ortofoto/">ftp://geoftp.ibge.gov.br/mapas/ortofoto/</a>).
My research says they're in epsg:31984.<br>
<br>
I'm trying to use MapServer's tile mode to display them on a Google Map API
instance, but can't seem to get any of the images to show up.<br>
<br>
Also, why am I required to give a PROJECTION statement as a child to the MAP
statement (what I assume is the "viewing projection") if the tile mode
is just going to reproject to spherical mercator?<br>
<br>
My .map file is below.<br>
<br>
Thanks!<br>
