I am still having problem with not seeing anything. Here is my code again for the map file.
#This is Richland County Map Server

END

STATUS default
TYPE polygon
DATA "RICH_bndy"
PROJECTION "init=epsg:26914"
END
CLASS

Is my code right? Can you help me?
Thanks,

Albert,Projection in MapServer isn't handled with an external file, like in ArcMap. It is done in the map file. Take a look at the Mapfile documentation to see how to do projection.You need to define a projection block in the MAP block of the map file, this is set to the projection that you want your data output in.You would then define a projection block in each layer, this is set to the projection that the original data for that layer is in. It is easiest to use epsg codes, look at example 2 in the link above.The epsg code for UTM zone 14N nad83 is 26914 and 4326 can be used for you lat/long data.David.-----Original Message-----Hi,

I was using a projection file UTM Zone 14n Nad_83. Then I switch to an unprojective file and I saw my data show up. What would be the first best step for setting a projection file?
Thanks

If the name of your mapfile relates to the data, I am guessing that Richland County isn't in this box.Use ogrinfo or a desktop GIS app to look at the extent of your data. Also, the extent needs to be in the units of the spatial reference system that your data is in.David.-----Original Message-----Hi,
