MapServer + Tilecache

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

Hi Tyler,
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. I think the "projection" and "srs" lines are conflicting with each other in your tilecache.cfg. 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. [v2_20m_global] type=MapServerLayer mapfile=/var/www/mapfiles/v2_20m_global/v2_20m_global.map metaTile=true metaSize=2,2 metaBuffer=0,500 layers=imagery spherical_mercator=true srs=EPSG:900913 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.

Hi Roger,
Definitely the problem is in the MAP file. I've removed the projection parameter, still doesn't work. Some parameters that I've not yet understand, namely: MAXSIZE and SIZE. I don't understand what I'm doing wrong. In Mapnik I just define srs="+proj=latlong +datum=WGS84" and is done.

Hi Roger, again,
Actually your last email solved the issue, many thanks! Still I don't understand why I must define MAXSIZE and SIZE.
