Hi Carla,
Please remember to use "reply to all" in order to send your message for the
mailing list as well.
I hope I understand this correctly. So your original data (the shapefile) is
in epsg:23030? Then you should have in mapfile, in corresponding LAYER section
PROJECTION
"init=epsg:23030"
END
Next, because you are willing to deliver that layer through WMS in epsg:4230,
it is good to add this to layer METADATA as
"wms_srs" "EPSG:4230"
By looking at my old mapfiles wms_srs metadata seems not to be compulsory if
WMS service will only be used in one output projection which is the same as the
main MAP projection. Anyway I believe it would be good habbit to have it.
Third, you should give the default output projection in MAP section as
PROJECTION
"init=epsg:4230"
END
And last calculate the bounding box containing your data in the mapfile
projection (epsg:4230) and feel in the values as EXTENT of the map object.
I try to read your messages once again faithfully and I feel you are giving a
bit conflicting information. In one place you say you are willing to publish
your data in ETRS89, wich I believe to mean epsg:4258. If this is the case
then insert that value to "wms_srs" and mapfile projection instead of 4230.
Why do you play at all with epsg:4230 if your data are not using it, and you
don't want to any output in that projection either? Perhaps I have just not
understood what you are aiming at, but I hope you will have luck with it.

Aihe: Re: [MAPSERVER-USERS] cs2cs problems
Thanks four your answer,
I've defined projections in my WMS before without problems. In this
case I want to change the projection of my WMS (to ETRS89) with the layers in
ED50, but if I just set the projection of the header's mapfile like ETRS89, and
I leave the layers' projections like ED50, it doesn't work :(
Do you have any idea of how can I use the cs2cs??
Thanks!!

Hi,
I you want to define projections in mapfile then there are two
alternatives:
either give the espg code:
PROJECTION
"init=epsg:2393"
END
or proj4 strings:
PROJECTION
"+proj=tmerc +lat_0=0 +lon_0=27 +k=1.000000 +x_0=3500000
+y_0=0 +ellps=intl
+towgs84=-90.7,-106.1,-119.2,4.09,0.218,-1.05,1.37
+units=m +no_defs"
END
But perhaps you are aiming at something else by using cs2cs?

Aihe: [MAPSERVER-USERS] cs2cs problems
Hi,
I'm having problems with the projection again. I've got a shape
in
epsg:23030 (ED50 UTM 30N), but I want to set my service in
epsg:4230
(ETRS89). I've changed the extent, the "wms_boundingbox" and the
"wms_latlonboundingbox" of my header's mapfile to geographic
coordinates
(epsg:4230 for ED50), and in the projection object (always in
the header, in
the layer object I leave epsg:23030) I put:
PROJECTION
'cs2cs +from +init=epsg:4230 +to +proj=4258 +no_defs
+no_defs +no_defs
+no_defs +ellps=GRS80 +datum=ETRS89 +no_defs +units=m'
END http://www.nabble.com/file/p16092875/epsg epsg
For the second reference system, I've also tried with
"+proj=longlat" and
with "+init=epsg:4258", but I get always the same error:
msProcessProjection(): Projection library error. projection not
named
The epsg file of my proj4 is attached (ms4w v. 2.2.7, MapServer
5.0.2)
Thanks in advance!!
