[Mapserver-users] Reprojection of shape file.

[Pericles Nacionales]

Why don't you run ogrinfo on your data and see if the extents are actually
in latlong?  Or if the shapefiles include a .PRJ extension, open it up and
see what the projection is.  If they are in latlong, run cs2cs to
reproject the extents to the stateplane cs.
