Hi,
Have defined also the input projection inside LAYER? It is necessary to know
both the input and output or otherwise it is not possible to reproject. If
layer projection is not given Mapserver is using the output projection as
default. That's why your first layer shows because it is originally in the
output projection or at least close to it. The other dataset is clearly using
another projection. It is odd to me, but perhaps it is this one I found from
the Mapserver epsg file
# NAD83 / Georgia West (ftUS)
<2240> +proj=tmerc +lat_0=30 +lon_0=-84.16666666666667 +k=0.9999
+x_0=699999.9998983998 +y_0=0 +ellps=GRS80 +datum=NAD83
+to_meter=0.3048006096012192 +no_defs <>
If that's the case you can use "init=epsg:2240" as input projection.

I have a mapfile in which I have specified the main output projection as
PROJECTION
"proj=latlong"
"ellps=WGS84"
"datum=WGS84"
END
Below is details of one of the layers that shows perfectly
Layer name: subdiv
Geometry: Polygon
Feature Count: 7
Extent: (-84.276822, 33.752808) - (-83.799104, 34.167873)
Layer SRS WKT:
GEOGCS["GCS_North_American_1983",
DATUM["North_American_Datum_1983",
SPHEROID["GRS_1980",6378137,298.257222101]],
PRIMEM["Greenwich",0],
UNIT["Degree",0.017453292519943295]]
Here is one more layer which is projected and I was expecting it to
change projection on fly. But it does not show. Below is the details.
Geometry: Polygon
Feature Count: 703
Extent: (1905254.375111, 1140017.900055) - (2497321.299899,
1670166.374861)
Layer SRS WKT:
PROJCS["NAD_1983_StatePlane_Georgia_West_FIPS_1002_Feet",
GEOGCS["GCS_North_American_1983",
DATUM["North_American_Datum_1983",
SPHEROID["GRS_1980",6378137.0,298.257222101]],
PRIMEM["Greenwich",0.0],
UNIT["Degree",0.0174532925199433]],
PROJECTION["Transverse_Mercator"],
PARAMETER["False_Easting",2296583.333333333],
PARAMETER["False_Northing",0.0],
PARAMETER["Central_Meridian",-84.16666666666667],
PARAMETER["Scale_Factor",0.9999],
PARAMETER["Latitude_Of_Origin",30.0],
UNIT["Foot_US",0.3048006096012192]]
I must be doing some mistake, can anyone help please.
Thanks and appreciate.
