Title: Richland County MapServer

Hi,

 This is what my map code look like
#This is Richland County Map Server
NAME "Richland"
SIZE 800 600
IMAGECOLOR 255 255 255
IMAGETYPE JPEG
SHAPEPATH "/home/mapdata/"
EXTENT -97.502192 45.947754 -96.330315 46.826661
WEB
  TEMPLATE '/var/www/htdocs/richland.html'
  IMAGEPATH '/var/www/htdocs/tmp'
  IMAGEURL '/tmp/'
END
LAYER
    NAME "Richland"
    STATUS default
    TYPE polygon
    DATA "RICH_bndy"
    PROJECTION "init=epsq:26914"
    END
END
END

I get this error now msProcessProjection(): Projection library error. no system list, errno: 2 ?  What does that mean?  How can I fix it?

Albert,

For each layer it's important to tell mapserver which projection your
data is stored in. In your case:

LAYER
...
PROJECTION
"init=epsg:26914"
END #PROJECTION
END #LAYER

The epsg code 26914 represents "NAD83 / UTM zone 14N". I think that's
what you're looking for.
