esri projection for wms srs value...

[John Cole]

Aaron,
  Thanks, both your projection statement and using the esri code worked:

PROJECTION
	"init=esri:102630"
END

  Now another question, how do I use that esri code or the projection
information in the wms_srs metadata section?

"wms_srs" "ESRI: 102630"

Doesn't seem to work :-)

Thanks again.

John Cole

John,

In the esri definition file with PROJ.4 (my version at least) the code
does exist (in feet).  I have never tried to use these esri codes, so
you can try to use it directly or just define your own using the same
parameters:

# NAD 1983 StatePlane Alabama West FIPS 0102 Feet
<102630> +proj=tmerc +lat_0=30 +lon_0=-87.5 +k=0.999933
+x_0=600000.0000000001 +y_0=0 +ellps=GRS80 +datum=NAD83
+to_meter=0.3048006096012192  no_defs <>

Trying to define your own in a mapfile might look like:

PROJECTION
  "proj=tmerc"
  "lat_0=30"
  "lon_0=-87.5"
  "k=0.999933"
  "x_0=600000.0000000001"
  "y_0=0"
  "ellps=GRS80"
  "datum=NAD83"
  "to_meter=0.3048006096012192"
  "no_defs"
END

Hope this helps...

Aaron

Thanks to everyone helping me to find the EPSG code, I was able to find
both the esri and epsg file in the proj directory.

Unfortunately, I had the epsg code correct (I was hoping it was wrong,
because the projection isn't working).  I'm trying to get a shapefile of
the Midwest states to work with a projected tiger county (epsg:26930).
I'm including the prj file for both the states and my county, along with
a mapfile and an image of what I'm getting.

I've been reading and searching, and I thought this should work, but my
north Alabama county is winding up in Maine.

Any help would be appreciated.

Thanks,

John Cole
