Hi

Maybe your EPSG reference number or bbox is not valid ( I can't find it in spatialreference.org). When I set up my tilecache for use EPSG:23700 with invalid bounding box I got exactly the same error!

  Hello,

  I am trying to set up tilecache.  At this moment I can only get tilecache to build the tile in the lower left corner.  The other do not show up at all.  The tile to the right of the lower left corner has an error: “An error occurred: Current x value 483991.068836 is too far from tile corner x 400000.000000.”

  I did figure out that the value 483991.06836=(the tile size (256)* resolution (328.090113) + left boundary (400000) is the left x value for 


  Any thoughts on how this can be fixed?


  Thanks
