Hi There,
I am trying to expose a wms layer where the original data is in
EPSG:28992. From reading through the mailing list, there were similar
problems/posts and my understanding to fix issues regarding that is to
update the OgcWmsService.config.awd file to add "SRS.WKT.map item with
the translate corresponding to the espg code. I have done that bases on
the config.awd file posted in the list. Restarted MGServer/Apache.
Doing the getCapbilities, I get the following on the layer :
<SRS>EPSG:28992</SRS>
<LatLonBoundingBox minx="0" miny="300000" maxx="300000"
maxy="600000"/>
<BoundingBox SRS="EPSG:28992" minx="0" miny="300000" maxx="300000"
maxy="600000"/>
which seems to indicate there is a problem with the latlong bbox.
The GetMap gives an exception The coordinate system is invalid.
EPSG:28992 Could not parse the OGC WKT.
Are there other places I should look for ?
Doing these tests on WMS, I have only succeeded to have a valid
interaction if the data is natively in latlong and defined with epsg:4326.
My trasnlate definition looks like :
<translate from="EPSG:28992">PROJCS["Amersfoort / RD New",
GEOGCS["Amersfoort", DATUM["Amersfoort", SPHEROID["Bessel 1841",
6377397.155, 299.1528128, AUTHORITY["EPSG","7004"]],
AUTHORITY["EPSG","6289"]], PRIMEM["Greenwich", 0.0,
AUTHORITY["EPSG","8901"]], UNIT["degree", 0.017453292519943295],
AXIS["Lon", EAST], AXIS["Lat", NORTH], AUTHORITY["EPSG","4289"]],
PROJECTION["Oblique_Stereographic"], PARAMETER["central_meridian",
5.38763888888889], PARAMETER["latitude_of_origin", 52.15616055555555],
PARAMETER["scale_factor", 0.9999079], PARAMETER["false_easting",
155000.0], PARAMETER["false_northing", 463000.0], UNIT["m", 1.0],
AXIS["x", EAST], AXIS["y", NORTH], AUTHORITY["EPSG","28992"]]</translate>
Thanks
