<div dir="ltr">Just answering my own question about this. It appears that the omission of a METADATA section in my raster layer mapfile was the reason that Tilecache wouldn't pick it up. After I added one to it, I had no problems anymore.<br>

<div dir="ltr">Hi,<br><br>I'm having a problem with the display of RASTER type layers from my Mapserver WMS. Basically, if I point the tilecache.cfg to a layer that is a vector type (POLYGON or LINE), Tilecache will properly read it, make a tile request, and cache it. However, if I change the layer in the .cfg to point to a RASTER layer, Tilecache doesn't seem to make the request, and no tile is generated. The only way I've found so far to display just the raster data with Tilecache is to call on both a vector and a raster layer at the same time, and set the opacity of the vector to "0".<br>

<br>Has anyone hit this problem, and is there a simple fix for it?<br><br>Thanks,<br><br>Roger<br>--<br><u><br></u>
