[mapserver-users] Reprojection from ETRS89 to ED5030

[darenas]

Hi everyone!

I have some problems to reproject WMS service from ETRS89 to ED5030 in tools
like ArcGis or gvSIG. I´ve defined all the layers with PROJECTION 25830
(ETRS89).

As majority knows there is an internal mapserver´s file called epsg
(\ms4w\proj\nad) where It´s possible to define diferents reprojections. The
definition line to define reprojection from ED5030 to ETRS89 is the
following one in my server:

<23030> +proj=utm +zone=30 +ellps=intl +towgs84=-87,-98,-121,0,0,0,0
+units=m +nadgrids=sped2et.gsb +no_defs <>

Therefore I suppose I have to change this line to inverse reprojection (from
ETRS89 to ED5030):

<25830> +proj=utm +zone=30 +ellps=GRS80 +units=m +no_defs  <>

,but I have no clue about it.

Any ideas?

Thanks in advance.

David
