[mapserver-users] Tilemode Projection Problem

[Ian Dees]

Hi everyone,

I've spent the better part of today scouring the internet for documentation
and help on the tile mode present in mapserver, but I couldn't find an
answer to my problem, so please forgive me if I'm missing some obvious
documentation some where...

I am attempting to show some GeoTIFFs (from here:
ftp://geoftp.ibge.gov.br/mapas/ortofoto/). My research says they're in
epsg:31984.

I'm trying to use MapServer's tile mode to display them on a Google Map API
instance, but can't seem to get any of the images to show up.

Also, why am I required to give a PROJECTION statement as a child to the MAP
statement (what I assume is the "viewing projection") if the tile mode is
just going to reproject to spherical mercator?

My .map file is below.

Thanks!

MAP

        END

                STATUS ON
                PROJECTION "init=epsg:31984" END
        END
END
