[Mapserver-users] Reprojection of shape file.

I have been assured the provided shape file is in WGS84 Lat Long. I want to keep
the original data in this and display it in NAD83 Stateplane Utah Central (US
Foot). Below are what I think the relevant map file chunks are. Basically when
displaying that layer I just get a blank image as if its way out of the
coordinates. Anyone see whats wrong?

NAME SLC
STATUS ON
SIZE 600 400
#EXTENT 1400000.0 7000000.0 1900000.0 7500000.0
EXTENT 1468185.000 7329845.000 1563785.000 7473605.000
UNITS FEET 
SHAPEPATH "data"
IMAGECOLOR 0 0 0  
IMAGETYPE PNG24

PROJECTION
 "init=epsg:2281"
END

LAYER
  NAME slc2002photos
  TYPE POLYGON
  STATUS OFF
  DATA slc2002photos
  PROJECTION
    "init=epsg:4326"
  END
  CLASS
    NAME "SLC 2002 Photos"
    SYMBOL "circle"
    SIZE 2
    COLOR 255 255 0
    TEMPLATE slc2002photos.html
  END
  HEADER header.html
  FOOTER footer.html
END


I thought perhaps Id try to convert the file manually and see what it looked
like. Im apparently doing something wrong here too.

[root at vad3rZIM data]# ogr2ogr -f "ESRI Shapefile" -s_srs epsg:4326 -t_srs
epsg:2281 trans slc2002photos.shp
ERROR 1: latitude or longitude exceeded limits
Failed to transform feature 0.
ERROR 1: Terminating translation prematurely after failed
translation of layer slc2002photos

Was I given bogus data?

Thanks, Jason.
