Hi, I guess the WMS 1.3.0 standard, page 15:
“Every Layer CRS has an identifier that is a character string. Two types of Layer CRS identifiers are permitted: “label” and “URL” identifiers: ⎯ Label: The identifier includes a namespace prefix, a colon, a numeric or string code, and in some instances a comma followed by additional parameters. This International Standard defines three namespaces: CRS, EPSG and AUTO2, as discussed below. ⎯ URL: The identifier is a fully-qualified URL that references a publicly-accessible file containing a definition of the CRS that is compliant with ISO 19111. -Jukka Rahkonen- Lähettäjä: mapserver-users [mailto:mapserver-users-boun...@lists.osgeo.org] Puolesta Luís Moreira de Sousa Lähetetty: 13. marraskuuta 2018 17:33 Vastaanottaja: Jean-Christophe Malapert <jcmalap...@gmail.com> Kopio: mapserver-users@lists.osgeo.org Aihe: Re: [mapserver-users] Using a CRS not indexed by the IOGP Hi Jean-Christophe, to which OGC standard are you refereing to, regarding the namespaces CRS, EPSG and AUTO?

I have modified the mapserver code to make it works (I have still a couple of tests to check everything is fine). However, CRS, EPSG and AUTO namespaces are defined by OGC. So, if you define a new one: - 1/ I am not sure it is compatible with OGC standards - 2/ I am not sure clients will understand this new namespace In my case, I have also written the client. If you are interested, I can share my current development about the mapserver code.

This CRS is defined within a specific PROJ namespace (e.g. init=namespace:001, just like others.extra or esri.extra) and is used correctly both by PROJ and GDAL. However, if I add this namescape to the "wms_srs" parameter in the mapfile, any request will be met with the following error message: msWMSLoadGetMapParams(): WMS server error. Unsupported SRS namespace (only EPSG and AUTO currently supported). I find this strange, is it only possible to use the CRSs indexed by the IOGP? Is there any way to convince MapServer to accept any other namespaces available in the PROJ database? I am awere I may create a fake IOGP index, but this is likely to create a good deal of confusion among users. I would rather make it clear this is a specific CRS.
