[mapserver-users] raster creation & use

[Stephen Woodbridge]

Joe,

Can you step back from the detailed problems for a minute, I want to
make sure I haven't lost the big picture of what you are trying to do.

IIRC, you are trying to generate base map images using mapserver.  By
capturing the png? images produced by mapserver and creating .wld files
for the images, then trying to get these tiled and lined up with your
mapserver again.

Is that correct? (or more likely just confused :)

Ignore the rest if my assumption is wrong about:

What is the output projection of mapserver? 
  (ie: your PROJECTION ... END section at the top of your map file.)

How are you stepping across the extents of your data to generate these
tiles?

How are the images mis-aligned? too big, too small, skewed, offset or
shifted up, down, left, right, or some of all of these or your not sure.

Have you tried to make one tile and bookmark the location where you made
the tile, then add a layer for the one tile with its, .wld file and go
back to the book marked url and see how the align/sizing is?

You seem to have too many variables in play right now, like is the
problem with the tile generation, the wld file creation, tile index,
mapserver layer definition, etc, etc, etc. You need to simplify the
problem so that we can identify the issue at its source.
