Hi Tyler,<br><br>I wonder if the "projection" line in your tilecache.cfg might be causing problems? From what you show below, it looks like your "vias" data is in EPSG:4326 natively, and that you then force MapServer to reproject it to a custom mercator - which you say works fine.<br>
<br>I think the "projection" and "srs" lines are conflicting with each other in your tilecache.cfg.<br>In my setup, I have my data's native projection defined in the mapfile like you do, as 'PROJECTION "init=epsg:4326" END'. But in my tilecache.cfg, I only specify what output projection I want, in this case EPSG:900913.<br>
<br>[v2_20m_global]<br>type=MapServerLayer<br>mapfile=/var/www/mapfiles/v2_20m_global/v2_20m_global.map<br>metaTile=true<br>metaSize=2,2<br>metaBuffer=0,500<br>layers=imagery<br>spherical_mercator=true<br>srs=EPSG:900913<br>
<br>My suggestion would be to remove the "projection line entirely and see if you get tiles generated in EPSG:4326 correctly. If that works, try specifying a different EPSG code. If you get reprojected tiles that way, you can try fiddling with the "projection" parameter in the tilecache.cfg, or add a new projection line to your /share/proj/epsg file with your custom parameters and point to its code in the tilecache.cfg "srs" line.<br>
<br>Best of luck,<br><br>Roger<br>--<br><br><br><div class="gmail_quote">On Wed, Nov 4, 2009 at 10:52 AM, Tyler Durden <span dir="ltr"><<a href="mailto:tylersticky@gmail.com">tylersticky@gmail.com</a>></span> wrote:<br>

I'm new to MapServer, until now I've used Mapnik to generate my tiles.<br>
But I want to try MapServer and I can't figure out what I'm doing<br>
wrong.<br>
If I run via WEB interface it renders fine, but with Tilecache the<br>
tiles appears blank.<br>
Any idea what I'm doing wrong?<br>
<br>
Thanks in advance.<br>
