Subject [jira] [Updated] (SIS-341) Support "crs-compound" in URLs
Date Thu, 12 Oct 2017 11:59:00 GMT

     [ https://issues.apache.org/jira/browse/SIS-341?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Martin Desruisseaux updated SIS-341:
------------------------------------
    Description: 
The {{CRS.forCode(String)}} method accepts URL in the {{crs}} space, like below:

{noformat}
http://www.opengis.net/def/crs/epsg/0/4326
{noformat}

We need to also accept URL in the {{crs-compound}} space, like below:

{noformat}
http://www.opengis.net/def/crs-compound?
1=http://http://www.opengis.net/def/crs/OGC/0/AnsiDate&amp;
2=http://www.codes.wmo.int/GRIB2/table4.5/IsobaricSurface
{noformat}

It should be possible to use this kind of CRS in GML like below (example from U.K. MetOffice):

{code:xml}
<cis:envelope srsName="http://www.opengis.net/def/crs-compound?
                       1=http://http://www.opengis.net/def/crs/OGC/0/AnsiDate&amp;
                       2=http://www.codes.wmo.int/GRIB2/table4.5/IsobaricSurface"
              axisLabels="Time pressure" srsDimension="2">
    <cis:axisExtent axisLabel="Time" uomLabel="ISO8601" lowerBound="PT0H" upperBound="PT48H"
/>
    <cis:axisExtent axisLabel="pressure" uomLabel="hPa" lowerBound="1000.0" upperBound="200.00"
/>
</cis:envelope>
{code}

If using the URN syntax, then this is rather a comma-separated value list (more description
in [Definition identifier URNs in OGC namespace|http://portal.opengeospatial.org/files/?artifact_id=24045]).
Example:

{code}
urn:ogc:def:crs,crs:EPSG:6.3:27700,crs:EPSG:6.3:5701
{code}
